Early Friday in Bird World

14 October 2022

Good Morning Everyone,

Some snow fell last night and it was still here – not melting – until half an hour ago. Everyone has been in the garden this morning and Canada Geese have been flying overhead. Everyone is visiting the garden. The number of Dark-eyed Juncos has increased, and the Starlings are here waiting for me to go and get Meal Worms and Butter Bark. I plan to do that shortly. They do cause chaos, but they are such beautiful birds and they also deserve a good feed on a cold day.

Making News:

Oh, I adored Rosa and Martin’s 2022 eaglet, Orion, at the Dulles-Greenway Bald Eagle nest. What a gorgeous chick. Orion hatched on the 13th of March. Well, guess what? Orion returned to the nest! But it gets better ———— Martin and Rosa were there!!!!!!!!!!!!!! Here is the video:

Harriet and M15, the famous Fort Myers Bald Eagle couple, have made The Washington Post with their rebuilding activities! The raptors can show us all the way. Don’t grumble about what life throws at you, just get on making it better!

Abby and Blazer from Eagle Country are on their nest tree. Just look at what Hurricane Ian did to their wonderful nest. I wonder if they will rebuild in the same place?

Do you adore the Kakapo, the charming green flightless parrots of New Zealand that are so threatened? Well, I do and am always thankful for the care they are given. They were New Zealand’s Bird of the Year for two straight years but, because of that, they have been struck from the ballot this year. Some are wondering if that is fair.

New research comes from all the poo samples collected of the Kakapo. Here are the results that shows gut health is key to their survival.

Nest News:

Today, at Port Lincoln, Big is 27 days old, Middle is 26, and Little Bob is 23 days. Those four days and, perhaps, a gender difference with Big Bob certainly being a female, sure set those two apart. According to Port Lincoln’s data chart, there were 4 fish delivered with 5 feeds. That does not tell us much about what happened on this nest. I was, however, delighted to see that Little Bob had a feeding around 0100 Friday morning. That is interesting as the night before, Middle had been the recipient of those precious bites. I could not rewind to see how much fish Little Bob got but, on Friday in Australia, Big ruled the roost in frenzied attacks on all the siblings. Little Bob had some fish around 10:45 before it was attacked by Big three minutes later. That feeding was highlighted in my last blog.

There was a feeding at 12:36. Little stayed rolled up tight and did not get any. The third feeding at 16:28 Middle got some but Little did not. It was the break through very large whole fish that helped Little Bob. It arrived at 17:17:45. Little Bob moved up to eat with Middle at 17:36 getting its first bite at 17:37:58. After that Mum worked that fish tail again giving Little huge bites at the end. Little Bob went to bed full of fish. That is a good thing.

There was not a late fish delivery like there had been the night before. It sure would have benefitted Mum and Little. Big is out for the count so full after gorging all day. I remember the second hatch at Achieve Ospreys in 2020. That osplet would eat and eat and eat so that Tiny Tot could not get any food. We wondered how it could even hold another bite.

Looking at Port Lincoln and the age of the Osplets, let us remember that the beaking started on day 8. The late and only fish delivery that day came after 1500. It was also the onset of the Reptilian phase. We are now moving out of the Reptilian Phase and this nest should settle —- if it is going to. It is why the ages of the osplets are now important as the development of their juvenile feathering. Oh how I wish we could measure their hormonal levels leading up to that Reptilian Phase and then coming out of it.

The chicks at Melbourne were once again left out in the hot sun yesterday. I am mystified at the female at this scrape. I have never seen a female consistently leave her chicks for an hour and a half or longer every day. They were so hot. Hopefully in another week – when, according to the Melbourne weather reports it is to get hotter – they will be able to run to the other end of the gutter for shade. I want to say ‘should Mum leave them alone in the hot sun again’ but, it seems that a pattern has formed and that is precisely what Mum will do, sadly.

Indigo and Rubus are being well fed and taken care of. Rubus now gets lots of food and you can see that it knows precisely where Mum’s beak is. The eyes are open and they are focusing. When Rubus is an adult it will be able to see a prey item a mile away. There were six feedings yesterday at Orange.

Rubus and Indigo are just cute little buttons of things. Indigo is so calm and Rubus seems to be a live-wire. I do love watching Indigo take food out of Rubus’s mouth – but, only if, Diamond replaces it for Rubus!

There is no news about SE29 or SE30. I will be back with updates on migration later today along with the breakfast news from the nests. For those watching the Finnish Ospreys, Salli left Finland on August the 25th and she arrived at her winter home in Rwanda on the 13th of October. She is now feeding at Lake Llaema. Fantastic. The adult Royal Albatross have been arriving on Taiaroa Head. Some have been around Lillibet’s nest. Check it out.

Thank you so much for being here with me. Take care. See you soon!

Big Bob and the beaking…Port Lincoln gets its first fish of the day

13 October 2022

Good evening, Everyone.

I couldn’t end the day without checking on Little Bob. When I closed my earlier blog, the Port Lincoln trio and Mum were waiting for Dad to bring in the first fish of the day. The osplets were already antsy and had been beaking one another. Each started the morning with a crop left from the late feeding last night but, by 0900 they had all dropped that crop and were hungry.

The first fish delivery arrived at 10:41:36. It was assumed, and rightly so, that Big Bob would eat the majority of any fish that arrived if not all of it. As it happened, Little Bob was getting some nice bites for several minutes even having a tug-o-war over a piece at 10:47:24. At that point, Little Bob had a small crop.

At 10:48:19, Big moves Middle out of the way so that he can brutally attack Little Bob. —The one saving grace this morning was that Little Bob did get up opposite Big and ate with his siblings. That is a big step from cowering yesterday and not even making a motion to eat. At 10:50:49, Big attacks Middle.

The long-awaited fish arrives. Even the osplets are fish crying to Dad.

Big is to the far left with Middle in the middle and Little Bob to the right.

At one-point Little Bob stands up to Middle and looks him in the eye. I just held my breath.

Little Bob has gotten some nice bites. Of course, not nearly as many as Big but, he is eating and he is up at the table and there is a small crop coming.

All is good and then it isn’t. Was the tug-o-war with Big and Big decided she had had enough of Little? I say ‘she’. Big is enormous. Not just from all the food she is consuming compared to the others but also because she has to be a female. It is also well known that the females are much more aggressive siblings especially if they are the first hatch. Their bodies will be at least 1/3 larger than the males and they have all those feathers to produce. They are often the last to fledge because of the time it takes them to fully develop compared to the smaller males.

Big is viscious. Just mean. She has had a lot of fish and yet, she is determined to terrorize the other two.

Then Big takes exception to Middle. Perhaps Big thought Middle had some food while it was dealing with Little. I want you to look at the size of Big’s wings and then look over at Little. Big is huge.

I have included this image. Big had a ps over the back of Little. I just want you to look again at the size. Little might have a peck at Big – which it shouldn’t – but Big is simply too big and could kill Little if she set her mind to it.

The fish is finished and both Middle and Little are fish calling at Mum. Let us all hope that much fish – great big fish – arrive on this nest today. Still, Little has eaten up at the table and that is a big step. Let’s watch and see what it does next time.

I wish I knew what it is that causes certain osprey nests to be more prone to siblicide and food competition. Is it toxins in the water? is it genetics? Is it just the psychological makeup of the osplets? is it gender? is it a mixture of all of these factors?

Thank you for joining me as I checked on Little Bob at Port Lincoln. Take care all. See you tomorrow.

Thank you Port Lincoln Ospreys for your streaming cam where I took my screen captures.

Wednesday in Bird World

12 October 2022

Good Morning Everyone,

I hope that all of you had a good start to the week. It is cooler on the Canadian Prairies today with really cloudy skies and reports of possible showers starting at noon. The animals have really been busy in the garden gathering nuts and eating. I wonder if we will have another cold snap? The European Starlings have come to the tree in the back lane but, for some reason they have not come to the garden. Is it because I have no Butter Bark or Meal Worms out for them? I plan to go and get some later today. We will see if that is what they are looking for.

Of the four nests in Australia, the real concern is at Port Lincoln and I will be monitoring that nest closely.

The gold star for the week goes to the male at Melbourne who really kept the nest together when Mum was away for over 3 hours and the hot sun was beating down on the youngsters.

To tell the difference between Dad (below) and Mum, look at the breast area. Dad has hardly any lateral barring – with a full crop, his chest area looks like fluffy Victorian handmade lace. Isn’t he adorable? I have come to love this tiercel so much. He has really saved the lives of these four eyases, now known affectionately in my house as The Melbourne Four.

Making News:

The causeway to Captiva and Sanibel Islands is now restored and vehicles are going in to restore communication systems, power, etc. This is incredible news. Who would have imagined this would be completed in October! (Not sure what was done or if private vehicles can travel but the causeway is functioning). Connie and Clive have been seen and photographed and Lena has been heard. Everyone is just waiting to get the cameras back up and running.

There are lots of boots on the ground checking for SE30. She was found on the ground being harassed by Currawongs and Magpies yesterday. She flew and seemed to be fine and was seen near the River Roost with a parent. That should put a smile on all our faces!

The text and images come from the Eagle Cam FB page.

I have seen no further reports on SE29 who was found in a residential area and taken by WIRES to a vet where it was receiving fluids and pain killers.

Sharon Dunne (aka Lady Hawk) has completed her tribute video to Lillibet, the Royal Cam Albatross chick, daughter of OGK and YRK, for 2022. As always, get the tissues out. OGK was last seen the middle of May on camera. It has saddened everyone to think that this fabulous mate and father has perished. We will wait to see if he returns for breeding season in October 2023. He was injured in 2020 and was away from the nest for 40 days. What a joy it was when he returned. Miss Pippa Atawhai was so happy. They had a very close bond.

Sadly, the Albatross continue to be killed at an alarming rate by the long-line fishing trawlers. As anyone knows reading my blog, there are quite a number of easy fixes to stop these endangered seabirds from being slaughtered. They include setting the lines at night – how easy is that?

Nest News:

The Melbourne Four continue to be well fed. At least three persons noted that there were 9 separate feedings yesterday. They were a mixture of stashed prey (as at breakfast) followed by fresh kills when there was not enough meat on the pantry item. Raptors eat everything unlike us humans who are said to waste 40% of all food we purchase. All of those pigeons are turning into beautiful falcons! Mum had her lunch time break (from 11:19:45-13:01:37). Thanks ‘H’.

Nine feedings. If they can keep the intruders away from their penthouse scrape and maintain their territory in the non-breeding season, we will have years of watching this incredible couple raise their families. The male has really stepped up and has actively engaged with the eyases and from his protective mode the other day has a strong bond with the little ones.

Port Lincoln Ospreys keeps a running timestamp of happenings on the barge. Its listing yesterday pretty much sums up what is happening. The nest has gone off the rails. Little Bob had a few bites of prey yesterday. It is so hungry that it is trying to take food off Middle’s beak. Big Bob is unrelenting in her (it has to be a female) rampage. The osplets are 25, 24, and 21 days today. In general, nests like this ‘settle’ at 28 days just like they start on day ‘8’. We have a week to go. Even then, nothing is guaranteed. The oldest sibling on this nest has pushed its younger off the nest at 65 days and killed it. It is going to be a long week.

Mum was up having a snack and she tried to reach down and give Little Bob a bite of fish while Big was asleep. The time is 01:27:54. Little Bob is awake but Big Bob moves. Oh, if Little Bob would just slide up and open its beak, he would get a good feeding.

Middle Bob did eat some fish along with Mum. Sadly, Little Bob never woke up. Both Middle and Little will be hungry but Little really needs to have a good feed.

You can see Middle Bob’s crop. I just wanted to shake Little and get it awake so it could it. That feeding would have made all the difference. Mum has fish leftover for morning but will there be enough for Little to eat or only Big?

At the scrape box of Xavier and Diamond in Orange, Australia there were six feedings starting at 07:46:35 and ending at 18:48:40. Rubus is getting some bigger bites. Both of the eyases, Indigo and Rubus, are adorable.

Little Rubus had a nice big crop before bed!

From the Bookshelf:

Do you love Hen Harriers as much as I do? Those beautiful owl-faced low flying raptors that can be seen over the heather? There is a new book out by Ian Carter that looks very promising, The Hen Harrier’s Year. Here is the review:

Book review: The Hen Harrier’s Year by Ian Carter & Dan Powell

So many factors play into a successful nest – lots of prey, healthy parents, no intruders…the list can be fairly long including Avian Flu. Despite all that has happened at Melbourne, that Peregrine Falcon nest is doing really well right now. That lovely tiercel is delivering fresh prey to Mum, the chicks are growing, and Dad has been able to help shield them from the sun during Mum’s noon day absences. Rubus is doing better at Orange. That wee one had a nice crop before bed last night. SE29 is in care and SE30 is being closely monitored. Thank you to all the boots on the ground near the Discovery Centre. The problem nest is Port Lincoln and this will not dissipate soon. We can only hope that Little gets one decent meal today.

Thank you for being with me. Take care everyone. I will be sending out breakfast news at the nests in the early evening. See you then!

Big Bob terrorizes nest

11 October 2022

I had not planned another blog today but events at Port Lincoln changed that.

The last fish delivery at Port Lincoln until today was at 12:48:22 yesterday, the 11th of October in Australia. Anyone observing this nest has noticed that it has become increasingly unstable since the day an only fish was delivered at 1500. Big Bob sensed that there was not enough food to feed all of the chicks and Mum and has been on a tear that has become brutal since that day. Much of the fury has been directed against Middle Bob and, indeed, today, Middle Bob got the majority of the wrath.

There was approximately 20 hours between the last delivery yesterday and the first one this morning. That was approximately 09:05. The camera was zoomed it and it was difficult to see the size of the fish nor how much fish each of the chicks received (I noted small crops on all of varying sizes later).

Big goes on a tear. Little Bob and Middle have been eating. He is the last up to the table and in the eldest sibling’s mind, no one is to eat before him. He starts beaking Little Bob at 09:06:50.

Once Little Bob is tightly tucked, protecting its head, in the submissive post, Big starts beaking Middle Bob. You just have to look at Big’s wings towering over Middle to understand how large Big is. Middle goes into submission. Big goes back to check on the fish. Of course, while all of this is going on, it appears that Mum is eating the breakfish fish.

At 09:08:38, Middle raises up and moves to try and get to the feeding by going around Little who is not moving. Big notices.

At 09:09:08, Big goes after Middle Bob. The attack was brutal and at one point it appeared that Big could push Middle off the rim of the nest. I was simply holding my breath. Big stops and moves up to eat.

At 09:13:44, Little Bob gets up and moves to the right of Big Bob to get some fish. (It is still impossible to see if any fish is being fed). Then Big goes back after Little.

At 09:17:32, Mum is picking up pieces of fish off the nest. Big continues to attack the siblings if they dare move.

It is going to take a lot of fish in quick succession to get any resemblance of stability at this nest. Even then, the brutal beakings may not stop. What was once about dominance is now about a fear for survival.

Thank you to Port Lincoln Ospreys for their streaming cam where I took my screen captures.

SE29 fledges and the Dust Ups continue at Port Lincoln

2 October 2022

It has been a really exciting day (and it is only mid-afternoon in Australia) with the first fledge at the Sydney Sea Eagles nest in the Sydney Olympic Park. One of the parents was on a branch of the natal nest when SE29 flew. Another parent was with SE30 later. And then SE29 returned to the nest tree. I am still trembling with excitement. While we don’t know where SE29 flew to – perhaps just the camera tree – what we do know is that the Pied Currawong did not chase this amazing eaglet out of the forest to the Salt Marshes. So happy.

I will not have an early blog tomorrow. I am going to post this right away. Look for news from all the nests later on Monday.

In my last blog, Big and Middle continued their battle for dominance of the Port Lincoln nest. The two are pretty much evenly balanced and each gives as good as it gets. Both cause the trouble. Sadly, wee Little Bob often gets caught up in the misery.

Interestingly, they are quite civil at meal times! There was a nice big feed around 10:20ish. Little Bob had no problem stepping right up by Middle Bob and opening its mouth for fish!

Then Big and Middle started scraping again.

Then a big fish arrived and everyone lined up nice to eat. Perhaps Mum should just sit on them between feedings until the pair of them calm down.

After Big and Middle had their feed, Mum gave Little Bob a private feeding. Give her a round of applause. Mum is working hard to make sure that each of her children is fed. Little Bob sure can consume fish but, he needs a fewer more feedings in between. He is entering the big growth spurt now. So far he has demonstrated no real fear of the two big siblings. He even took a fish flake from Big Bob’s beak earlier.

There is enough fish for everyone.

At the Sydney Sea Eagles nest, the time for fledging draws nearer and nearer. On Monday morning (Australia time), SE29 flew to one of the lower branches of the nest tree. S/he waited there for a bit and then…did not fly off but rather, returned to SE30 in the nest. Bravo!

At 13:44:30 SE29 fledged. S/he had watched one of the parents on the branch and was looking over the edge of the nest and just flew. It was beautiful. Congratulations to everyone at Birdlife Australia and all connected with the Sydney Sea Eagles.

A parent waits with SE30. The siblings were so close to one another and what a fantastic year it has been with them and Lady and Dad. I wonder if SE30 will leave today or if SE29 will return later? We wait to see.

At 14:46:58 SE29 returned to the nest to join SE30 and the parent. Tears are just rolling down my cheeks. This is incredible. Normally the Curras chase them out of the park – it didn’t happen today.

Tears of joy.

Thank you for being with me for this great event. SE29 flew!!!!!!!!!! And SE29 returns safely to the nest.

See you soon — and take care of yourselves.

Port Lincoln Osplets – another dust up this morning!

2 October 2022

Thank you to everyone for their notes and concerns about what is happening at Port Lincoln.

Yesterday there was a prolonged period of beaking between Big Bob and Middle Bob that lasted in excess of six minutes. Little Bob literally was in the middle of the fight and sometimes because an object of abuse but, only a few times.

Big Bob woke up on the wrong side of the bed this morning. S/he has been beaking Middle all over the nest when Mum was not present. Big has also had Little Bob between her legs beaking him. It is not a nice situation.

It all seems to have stated, as often happens, on day 8 so the strife has been going on for a week. It is not clear how it will end. The beaking became worse after a single fish delivery at 1500 in the afternoon caused Big and Middle to immediately switch into rivalry mode for dominance. The osplet that dominates the nest gets to eat more than the others, etc. Big and Middle, at times, seem to be evenly matched. Little is too small and just needs to try and get out of the way. This morning, however, Big had Little between its legs pecking at Little’s head.

Mum came in and sat on the three of them. It is often the only way to stop it and Ospreys and Eagles are notorious for not interfering.

Let us hope that lots of fish arrives and that the rest of the day is civil. Little is very vulnerable right now.

Oh, I wish we could brag about what a lovely bunch of osplets there are this year – like last with the three boys, Bazza, Falky, and Ervie. I think we have at least one large female this year, if not two.

Thank you to Port Lincoln Ospreys for their streaming cam where I took my screen captures.

Thank you for being with me. Let us all send the most positive energy we can muster to this nest.

Late Sunday in Bird World

3 October 2011

Hi Everyone,

I cannot describe what a beautiful fall day it was out in the forest. The wind was only blowing at 2kmh. Leaves – the most gorgeous yellow, red, and orange were falling gently. Seven Black-capped chickadees, a few American Goldfinches, a sole White-breasted Nuthatch, and that lovely Red Squirrel kept me company at the hide. Oh, they must be so happy it is not raining and it is not too hot or cold – just right at 21 degrees C. It could not have been more perfect for humans or wildlife.

It seems that everyone was after the peanuts. They are so good at getting them out of the shells!

This beautiful White-breasted Nuthatch spent about 10 minutes at the feeders before flying off.

The little squirrel was enjoying all of the nuts on the forest floor. These squirrels are very lucky. There are Oak trees and acorns everywhere!

There were more geese on the ponds today than when I went to view them at dusk. There were only a few up in the grassy areas resting on a warm day.

The colours are changing. Autumn is my favourite time of year…it would just be nice if it would last longer! You can sit on the bench, close your eyes, and open your senses up to the smell of the leaves and the geese honking in the distance. Magical. Just try to be grumpy after sitting there for a half hour!!!!!

This Mallard was having a great time splashing about. What a bath.

And then…there was no mistaking the ‘Little Duck’. It remains the tiniest duck in the entire pond BUT — look, all of the back feathers are now in place. This duck cannot be more than 45 cm (8-9 inches) from the tip of its tail to the end of its beak. It looks larger in the photo but, it isn’t – and that is how I knew it was the wee one. (I did come home to compare with the former images just to make certain that the head line and beak were the same before I made a complete idiot out of myself). This tiny gaffer is a Blue winged Teal. It is positively adorable. I sure hope it gets a good wind to carry it south with those itsy-bitsy wings.

Besides finding the little duck, one of the great moments of this afternoon was seeing ten Cormorants in a tree sunning themselves on a beautiful day. Sometimes the Bald Eagle couple are up there in that tree. It is on a peninsula jutting out and there is no way for humans to disturb them. What a beautiful site. When I was standing admiring them, a couple walked up and told me that twenty years ago you would not have seen a Cormorant here. I felt blessed.

Whenever I am outside and getting tired, it is simply nice to remember that I am so lucky to be able to walk in the woods and be outside with nature. I know that many of you cannot – so I am taking it all in for you, too.

In the Mailbox:

So many of you have written to ask me if I think that any more eggs will hatch at either the Collins Street scrape in Melbourne or Xavier and Diamond’s scrape in Orange.

I do not expect the fourth egg at Melbourne to hatch. Falcons and hatch practice delayed incubation. This means that they will not incubate the eggs 24/7 until most of them are laid. This is so the chicks will hatch close together and not have issues of siblicide and food competition like exists in eagles and ospreys.

If a second egg is to hatch at Orange, I would really expect this to happen today or tomorrow. That said, I am not completely hopeful of another hatch there. Xavier and Diamond tend to have one hatch per 3 eggs.

I just received 3 letters with questions about siblicide. I presume that this subject has been brought up on chat or FB somewhere today.

The answer to your questions depends on the species and the circumstances. There are species of eagles where siblicide is almost always 100% (Black, Golden, Imperial). The eldest hatch always kills the youngest. Always. No wishing or hoping. Always. Siblicide is rare in hawks and falcons with most studies showing less than 1%. The stats come from watched nests. The average siblicide from studies at the University of Oklahoma is 3.8-4% in Bald Eagles. It is presumed to be the same or nearly the same in Ospreys. Some nests are more prone to siblicide than others. A good example of a nest where siblicide regularly occurred until last year is the Port Lincoln Ospreys. There is a history below the streaming cam that you can examine. The % at this nest would be much higher.

‘H’ wrote about the torrential rain and high winds blowing along the NE of the US because of Hurricane Ian. She has sent an image of a bird that has landed on the nest. It is banded. I believe it to be a juvenile Peregrine Falcon but I could be wrong. It is ahrd to identify birds when they are wet. So I am posting it here if anyone has any other ideas. This is the shores of Delaware at Mispillion Harbour. Birds are being blown off course. This one has two fresh new bands. Does anyone recognize them? If so, please send me a comment.

Nest News:

So it is time to check and see what is going on in Australia- when we left everyone yesterday afternoon, the Port Lincoln kiddos all had crops, the three at 367 Collins Street had been fed, the Sea Eagles were looking magnificent with SE29 basking in being up on the parent branch, and Xavier and Diamond had one beautiful eyas. Has anything changed today?

Diamond and Xavier have already fed their wee eyas twice this morning (it is 16:44 on the Canadian Prairies). The first was around 0533 and the second

The three eyases at 367 Collins Street have also had a good morning feed. I think that we can all relax and enjoy this new family learning how to parent in Melbourne. The male has brooded, shaded the chicks, fed them, and is bringing prey for Mum and them. It is time simply to sit back and watch these marvelous falcons grow! In less than 40 days they will be full grow and flying! So hold on – it is a fast ride!

The osplets at Port Lincoln were waiting on a breakfast fish to be delivered.

The two eaglets on the Sydney Sea Eagle nest are still home this morning! They are also waiting for breakfast!

Thank you so much for joining me today. Please take care. See you soon!

Remembering Lindsay…and more. It’s Friday in Bird World

26 August 2022

Amidst the joy of Peregrine Falcon eggs in Australia at both Orange and Melbourne, the loss of dear Lindsay, the eldest of the two siblings hatched at The Campanile on the grounds of the University of California-Berkeley, remains heavy – a real heartbreaker. From the news it is apparent that Lindsay died several weeks ago; her body just being found today. She was last seen on the Campanile on 5 August precisely three months after she hatched on 5 May. A life cut way too short.

Lindsay was one of a two-part miracle. Lindsay’s Mum, Annie lost her mate Grinnell when he was killed after chasing an intruder away from The Campanile. There was worry that there would be no chicks this season. Alden arrived in 5 or 6 hours hours (already a friend of Annie and Grinnell’s) and offered to help Annie incubate the eggs and take care of the chicks. We rejoiced at the love the two siblings had for one another, when they played, and when they chased moths. They grew strong and they flew. It is with such deep sadness that we say goodbye to Lindsay today. Fly high, Sweet Girl. Soar to new heights you never imagined.

Here is the full announcement from Cal Falcons. It appears that Lindsay’s death, from the evidence found from her body, was killed by another raptor.

It is heartbreaking. Lindsay had such potential and, of course, it is very possible that she was the last chick our beloved Grinnell fathered. She brought us such joy! I would like to share a few images of this remarkable falcon moving back in time from the last sighting of her on The Campanile on 5 August to the day she hatched.

Lindsay and Grinnell, Jr adopted many of the quirks of Alden including loafing. Annie has perfected it!

Annie and Grinnell, Jr playing together at The Campanile. The two siblings seemed to really enjoy playing with one another, something that I have not seen for a long, long time. It was refreshing.

Lindsay on the roof of the library on 18 June after fledging. Just look at this exceptionally beautiful juvenile. Stunning.

Do you remember banding day 27 May (on the right)? Lindsay was frightened but quiet. Alden would not stop being loud! Lindsay was still sit ting with a not so scared look on her face in early June.

Lindsay was also sitting in that same pose on 22 May.

Hatch day for Lindsay, 5 May. Grinnell wants to come and help. Annie is not sharing – yet – but she will and each of us will rejoice watching this wonderful family.

‘H’ just sent this press release on Lindsay. Thank you, ‘H’. Just made it before I hit send! Grateful.

From the Mailbox:

‘M’ writes: What do you think about this from Dyfi project? I am not sure I would pass off some of that behaviour as just “playing”, at least not based on how the smaller chick reacts. Wondered about your view, based on your study of third hatches.”

For transparency, I posted the information from Dyfi in one of my blogs. Emyr Evans has a long history with the Dyfi Nest in Wales. I have great respect for him but, in this instance, I choose to disagree.

In the UK Osplet deaths are generally attributed to either very poor weather in the early days after hatching or lack of prey, starvation not siblicide. There is little history of siblicide; there are so few breeding pairs and chicks compared to North America. This year, however, we did see it at the Loch of the Lowes Nest. It was rather horrific treatment of the third hatch that was killed by the eldest during a period of low prey delivery.

As you are aware, my research is on siblicide and, in particular, the success of any third hatch osplets vs the other two siblings. Because I track the juveniles long term this is limited to those that are ‘ringed’ and/or ringed with SAT tracking. My findings also rely on the good fortune of someone seeing the juveniles in the future and providing that information to various data bases! In my experience, the aggression shown by older siblings ranges from mild displays of dominance to more serious concerns that seem to taper off around the age of 26-28 days. Serious aggression often ends in the death of the smaller weaker sibling. There is much research to support the fact that it is not always about food. Sometimes it is just dominance.

‘M’ this, in my opinion, is not play. It is establishing the dominant bird on the nest. The dominant bird will eat first and if there is little food it will be the only chick that eats. Had food been scarce the treatment might have escalated but, thankfully, it didn’t. Gender may play significant roles also with the females requiring more food to grow 1/3 larger and feather a larger body. Thus, the females, especially if they are the first hatch, tend to be more aggressive.

Multiple times this year we have seen the third hatch killed by the eldest sibling and sometimes in conjunction with the middle one. As mentioned, this happened at the Loch of the Lowes this year when food was scarce. It also happened at the UFlorida-Gainesville Osprey nest amongst others. It also happens on eagle nests and other species. However, there appears to be a higher rate of siblicide among North American Ospreys than those in the UK. It is likely that these numbers reflect the higher population of Ospreys in North America. In addition, the lochs are full of fish and there are restrictions on many of them to prevent human intrusion during the breeding season.

In the News:

We are going to start with some fantastic news. When I lived in the UK, I studied in Leicester but lived in Lincolnshire and Belvoir (pronounced Beaver) Castle was a regular haunt for me – so close to where I resided. For the first time in 200 years, we have Ospreys breeding on top of Belvoir Castle! Oh, my goodness. I am delighted. Here is the BBC News report.

Bird Flu is also killing Black Vultures. Deaths from migration, Avian Flu, human disturbance and killings, fires, habitat loss, lack of food…how many of our raptor friends will be left?

There is a lovely documentary on YouTube on the return of the Black Storks to Germany in the 1980s. The cinematography is excellent as is the narration. So much to learn – 53 minutes. Find a nice quiet time to watch!

Nest News:

The 367 Collins Street Falcon Cam in Melbourne is up and running. So far there are 2 eggs!

Here is the link to the camera:

As you will be aware, the first egg of the season for Xavier and Diamond at their scrape in Orange was laid at 0713:48.

Diamond resting in the scrape after her labour and the delivery of the first precious egg for these two.

Diamond incubating the egg. How beautiful.

Xavier comes to the scrape to relieve Diamond. A short bonding ritual takes place before Diamond flies off.

Xavier scraping and trying to turn the egg as he settles down.

Xavier carefully rolls the egg.

Everything is alright with the world. Oh, what a joy to finally see the first egg for Diamond and Xavier. Let us all hope that their year is as successful as it was in 2020 with the hatch of the ever adorable Izzi.

Here is the link to one of three cameras for Xavier and Diamond:

I am so used to the Ospreys in the UK and the Dads bringing in a fish right before or when the sun is rising in the morning. That first fish delivery for SE29 and 30 at the WBSE nest in the Sydney Olympic Forest did not come until 12:31 today. Thankfully the chicks were civil and it was not huge but was a good size.

Images from early morning to feeding.

Early morning preening of those itchy feathers.

Beautiful Lady listening and waiting for Dad to bring food to the nest.

SE29 and 30 watching Mum aerate the nest. Just look at how carefully they are looking at her every move. This will imprint in their mind’s and they will know to aerate their own nests.

Finally, a fish has arrived!

Things appear to be going good at the Port Lincoln barge except for Mum making cries for fish. On occasion Dad has flown in eaten more than his fair share while Mum is fish calling. He then delivers the remainder to her. Come on Dad! Dad is taking his turns incubating.

Oh, it seems so long until 19th of September – may the time pass quickly! There is nothing cuter than nestlings a couple of days old.

Checking on Kaia’s transmission. She remains in Belarus. On the 25th of August she flew 123 km. She is now near the village of Liaskavicy. It is in an area that is part of the wetlands of the Pripjat River. There is a national park and the area is considered to be quite safe for Kaia.

Karl II is looking a little tired. Thanks to Urmas the supply of fish continues so that he can feed the four Black Stork fledglings. Soon they will fly and hopefully Karl II will have some days to recover and gain some weight before he leaves. Of course, when they do depart we shall all be worried for them. I wonder if by some means Karl II and the children will meet with Kaia and decide another route to their winter home???

It appears that all of the White Storks from the nest in Mlade Buky, The Czech Republic have left for their migration. It is raining heavily and both of the nests of Bukacek and Betty appear so lonely. Safe travels dear family.

Suzanne Arnold Horning has caught L2 on the Cornell Campus! So happy she is here with us. In the history of the nest, it seems that the 28th of August is the last day to see fledglings in the past. Enjoy these moments then with our first fledge of the year. Gosh, she is beautiful. We know that she is catching her own food – she was the second of the fledglings to do so more than a month ago. So all is well with L2.

It is Friday. A friend sent this to me to cheer me up because of Lindsay. I did giggle…love those sour worms. Thank you ‘S’.

Thank you so much for joining me today. If you have any questions, you can send them through the comments page or through e-mail. My address is maryannsteggles@icloud.com Have a fabulous Friday! Take care of yourselves. See you soon.

Early Wednesday in Bird World

27 July 2022

I am starting to write tomorrow’s blog on the evening of the 26th because there is good news at Osoyoos. It is a lovely evening on the Canadian Prairies. It is nearly 2100 and the garden animals have departed to their sleeping quarters. I would love to know where they go. It is cooler here, we have had lots of rain and the hot weather seems to have passed – for now. The clouds, however, are coming and looking strange and you can hear thunder in the distance.

It was certainly a relief to go onto the Osoyoos Osprey cam and see the time stamps that ‘A-M’ had listed for the fish deliveries by Olsen. Fish at 0510, 0524, o554, 0616, 0943, 1103 and 1633. Apparently all of the fish were a good size but the first one. This is fantastic. It just seems unthinkable that anything could cause these two beautiful osplets not to fledge.

It was also a good evening because Ferris Akel was on the Cornell campus in Ithaca looking for Big Red and her family.

Big Red looks as if she is beginning to moult. L2 has a much whiter than L4 but in these images it is truly hard to tell which juvenile is which. What is important is that all are safe and sound.

One of our readers, ‘J’ has written about the Sydney Sea Eagles SE30 and its attacks on SE29 when the two are alone on the nest. Yes, it is true that is happening and yes, 30 does, at some feedings, become submissive to the older sibling which is larger.

I remember when I began watching the Sea eagles. One of the moderators at the time told me that typically the second egg is the ‘insurance ‘ egg. It is only there if something should happen to the first hatch. Of course, I was horrified. At the time I had not had any experience with some of the other eagle species where the eldest hatch always kills the youngest. In some instances, the age difference impacts this even though there is lots of food on the nest. In other instances, it is simply ‘standard practice’ for the eldest to kill the youngest. This is known as obligate siblicide. I want to be clear. I am not saying this is what is happening at the Sydney Sea Eagle nest in 2022.

At the Sydney Sea Eagle nest there has been plenty of fish so far this year. The chicks hatched relatively close together and, observations over the past five years show that there has always been some initial competition on this nest;; once this resulted in siblicide. In fact, sibling rivalry with SE23 began on day 5 in 2019. The rivalry ended in week 6. In 2018, there was also sibling rivalry with SE21 becoming dominant often pecking 22 who would retreat in submission. That rivalry period lessened after 3 weeks. Sadly, there was a period of 6 days when the male did not bring any food to the nest. The female hunted but the prey was so much less and SE22 was constantly attacked, becoming weaker and finally dying on day 33. In 2019, 2020 and in 2021 both eggs hatched each year and both chicks fledged. So the last time there was siblicide on this nest was 2018 and that was the result of 6 days when the male did not bring food.

For those constantly watching the Sea Eagles nest, just take a deep breath. Hope for continued good prey deliveries and wait. There is a strict no intervention policy at the nest (or there has been in the past) and I have no reason to believe that this has changed. Wishing it to be so will only cause personal angst and frustration. If things get bad, this is what I suggest – take a three day break. Then go in and check on the nest and see how the younger one is doing.

Whenever individuals – and we all have – worried about dominance competition, I like to go back and look at one of the videos from the SW Florida Bald Eagle nest. In particular, one of E19 and E20 who, at the end, were the best of friends. The year prior, many will remember E17 having to go to ‘time out’ at the CROW clinic when it was so aggressive to E18. They were inseparable twins when they fledged.

Here is the announcement for the discussion with Christian Sasse and those wonderful folks from GROWLS. Please note the time in the posting below. This will take place on YouTube.

For those of you that love those UK Osprey nests, take note. I was reminded by my calendar and friends in Wales that the countdown to migration has started…by 4 weeks from today, the females should have or be departing, followed by the fledglings and finally the males. So enjoy them while you can!

Just a few images from the UK nests this morning.

Of course, migration begins in North America also. If you want to keep track of North American migration in the east, there is no better place to go to see the numbers than Hawk Mountain in Pennsylvania. What is Hawk Mountain? Founded in 1934 by Rosalie Edge, Hawk Mountain became a sanctuary for migrating birds – not a killing club. Edge initially purchased 1400 acres of land which has now been extended to 2600. The thermals over the mountains are perfect for the migrating birds to soar. You can visit the centre and even take part in the great migration count or you can watch the numbers increase from August to mid-December. Here is the link to the chart for the Hawk Mountain fall migration count.

If you are wondering about the drama playing out at the Whirley Crane in SF Bay home to Rosie and Richmond, here is the latest news. Please not that Brooks has come to the nest at least once but was chased away by the visitor.

The day has started early in Osoyoos with Soo feeding a small fish to the two chicks and herself. Hoping for lots and lots of early fish today as those temperatures are set to soar in the afternoon.

Those two are growing and they are so cute….wish for fish everyone!

There is sad news coming out of Estonia. The camera at the nest of Eedie had gone down. One of Jan and Janika’s chicks had been fostered there. Urmas has just announced that all four of the Black Storklets have been predated. This is a terrible loss. Of the three nests, Eedie, Jan and Janika, and Karl II and Kaia – only 4 storklets survive. The four in the images below will now have to fledge and then survive flying through the Ukrainian War zone and other dangerous places to reach Africa during the fall migration.

At the Karula National Forest nest of Karl II and Kaia, there is good news. Karl II did find the second fish basket that Urmas set up for him. This is wonderful as the feedings had been getting quite lean. Here is Karl arriving with a feeding for the four. Now, Bonus, the foster chick on this nest is the only surviving storklet of Jan and Janika.

One of the chicks at the Janakkalan Osprey nest in Finland is really getting some height to their hovering. Expect a fledge soon! It is so exciting. So much has happened on this nest – illness and presumed death of the Mum and starvation death of a sibling, an intruder – that we shall really celebrate when these two surviving youngsters fledge.

One last check this morning and that is at the Boathouse. The dancing diamonds from the sunrise make it nearly impossible to see what is happening on the nest but…it looks as if one of the chicks of Dory and Skiff is trying self-feeding! Oh, fantastic.

Thank you so very much for joining me this morning. Keep sending your best wishes to Osoyoos for fish deliveries today as those temperatures climb to 41 C or 102.5 F. Take care everyone. See you soon!

Little Bit ND17 is still the ‘King of the Snatch and Grab’ and other news in Bird World

15 June 2022

We needed some good news in Bird World after Big Bob plummeted Little Bob at the Loch of the Lowes to death earlier this morning. That nest, by the way, is not any happier. Laddie brought in what looked like a minnow. Blue NC0 and both chicks will be quite hungry. I wonder what is up?

But, never mind! At the ND-LEEF nest there were two fish brought in before 10:00. The first was a Sucker delivered by Mum and the second was a Blue Gill brought in by Dad.

At 05:53:51, the sucker arrives. Little Bit 17 gets it first. What did I tell you. Then he loses it. Then he steals it again — twice!

At 09:45:53 Dad brings in the Blue Gill. ND15 gets it. At 10:01:03, Little Bit 17 steals it. Boy is this kid good. He grabs it, does the most amazing turn around and runs to the porch to eat it!!!!!! Wow. Is happiness spelled fish???????? It is cooler – 78F. Yesterday it was 96 F at the nest. Let us hope more fish arrive if it is to be ultra hot later.

The sucker arrives at 05:53:51. Little Bit will get it first, lose it and steal it again twice!

Little Bit 17 is very clever. He has had to be to survive on this nest with two much larger siblings and often, little prey. His head shows that he has also paid for trying to steal food to live. So, he sits and watches 15. 15 is not hostile to Little Bit like 16 is.

Little Bit watches and listens and plans its attack.

When he sees the right opportunity – meaning he can see that he can grab the prey and get out – he goes for it. He grabs. Turns back to the right like a ballet dancer doing a pirouette. Then he moves quickly to his safe spot – the porch.

ND15 raises its wing. Little Bit 17 has the rest of the fish and is getting to the porch. What is really incredible is we are talking about an event that only took seconds.

This is thought to be ND16’s first branching – at 10:06. We don’t know what happened when the camera was off. This is good. 15 has already branched and maybe 16 will be more concerned with flying than with Little Bit.

The temperature has now jumped and it is hot. Thankfully – due to his great stealing skills – Little Bit 17 has had some food and hydration.

It is week 4 at the Osprey nest of Richmond and Rosie on the Whirley Crane. San Francisco Ospreys posted their weekly update video of the family. Do we have names for these? Not yet, in a few days. Should I mention that there is no problem with fish delivery at this nest?

Congratulations to Pittsburgh Hayes 18 who fledged this morning at around 11:17. (or is it a fludge?). Upper left branch – lots of leaves and flies off from there! Well done.

We are into day 2 of fledge watch at Cal Falcons. It is hard to believe that Grinnell Jr and Lindsay are really ready to fly!

They can look through the openings to see the world outside that will soon be theirs.

L4 was on the nest with L3 this morning. Beautiful little hawks of Big Red and Arthur. There is a storm coming in on Thursday so fingers crossed that L4 decides not to fledge! What a cutie pie.

The storklets of Jan and Janika had a good feed not that long ago. They are doing extremely well. The staff and all those involved must be terribly happy so far.

We now know that Betty at the Mlade Buky White Stork nest eliminated the youngest chick, the 5th, a couple of days ago. Now Kaia, the mate of Karl II, has tried to eliminate one of the storklets. They are all big! Everything is currently normal on this nest. Kaia might perceive that there is not enough food. She does not know that Karl II has been bringing in lots and lots of food. Let us hope that all stays normal with all the chicks! Send positive wishes.

Today there will be an on line presentation and Q & A about the Bald Eagles on Gabriola Island in British Columbia that have adopted the Red tail hawklet. It was brought in as prey on 4 June and is currently being fed and cared for by the eagles as if it is their own.

Go to this YouTube site to set the reminder if you wish to be part of this discussion. I cannot tell you the time in your zone as YT automatically sets the time remaining to my specific zone which is 15:00 CDT.

There is super news coming from the Glaslyn nest of Aran and Mrs G. Aran fed his three chicks of 2022 for the first time today.

It was pitching down rain at Loch Arkaig. Poor Dorcha and the two surviving chicks. Louis was able to bring in a fish as things began to clear. Please keep this nest in your thoughts.

Seren and Dylan on the perch together with the three Bobs in the nest below. What a gorgeous family portrait and what a beautiful site in Wales for an Osprey nest. All is well here.

Telyn and Idris have been keeping intruders away from the nest. Gosh these returning two year olds can be a nuisance that can also cause harm to a nest. Reminds me of the juveniles returning to Taiaroa Head when the chicks are on the nests alone and they dance and sky call and pick on the little ones.

There has been the osprey in the image below briefly visiting the Cape Henlopen Osprey nest. I cannot identify it other than it does not appear to be the Mum because her necklace was very faint. I could not see the feathering to tell if it was the intruder female that removed all of the osplets.

Spirit spent the night with Jackie at the Big Bear Valley nest in California. How reassuring is it to see these beautiful fledglings return home – safe and sound?

I really wanted to give you the good news about ND17 so I am posting much earlier than planned. While 17 didn’t get a whole fish – and it is getting hot – he did get food and he is definitely not lethargic like the Loch of the Lowes osplet.

It is the first sunny day we have had and rain is to come again at 1800. My plan is to be outside in the garden listening to the birds! Thank you so much for being with me today. I will be posting again on Thursday morning. Take care all.
