Viewers of the Port Lincoln Osprey Barge are starting to wonder if Bazza isn’t eating so much fish that he can’t get lift off the nest. He sure does love his fish.
At 08:00 Dad flies in with the first fish of the day. Falkey gets that one fighting off Bazza who would just love to have breakfast. At 8:50, Falky is full and he walks away leaving a beautiful fish tail on the nest. Ervie spied it immediately and finished that off quick.
They remain such a civil trio. There is Falkey getting to enjoy his breakfast.
Ervie turns around and probably doesn’t believe his luck – a nice fish tail just in front of him. He was there claiming it in the snap of a finger.
Ervie made quick work of the fish tail. Falky is full and Bazza really doesn’t seem interested.
At 09:36:53, Dad flies in with another fish, quite a large one this time. He puts it right at Bazza’s feet. Talk about luck. Bazza was still eating on that fish an hour and a half later. I don’t think he will be leaving too many scraps.
Just look at the size of that fish!
Bazza is still eating. My goodness. It could be true. Maybe he is too big for take off. Bazza certainly seems to be wider than the other two lads.
Do you follow the falcons at Orange? If so, then you probably know that this is the one year anniversary of last year’s chick, Izzi’s fludge. For those unfamiliar, Izzi was the only hatch of Diamond and Xavier in 2020. He dozed off on the ledge and literally fell out of the scrape box. Cilla had to find him and carry him back up the 170 steps to the box. When he did fledge, the first time, Izzi flew into a window and went into care. Cilla returned him to the scrape to do it properly the third time. Isn’t that what they say? The third time is a charm. It worked. In memory of the fludge, someone has put together a video clip of it and Izzi being returned to the scrape.
As for ‘Little’ Yurruga, Xavier delivered three prey items for his daughter before 06:45! Diamond will come in later and help Yurruga but she is doing a good job of the self-feeding. I love how she watches Diamond so intently when she is plucking and eating – memorizing / imprinting it all.
Rumours are circling that the WBSE Juvenile will be released from care into an area around the Newington Armoury by the Discovery Centre in the Sydney Olympic Park. The juvenile injured by the Curras is believed to be 27. (There are some that believe it is 28 and with no bands and no DNA who knows.)
There is really not a lot going on in Bird World. Waiting for Bazza to take the leap, waiting for some of the first Bald Eagles to lay their eggs, waiting to find out who is the Royal Cam Albatross family this year. Feels like a lot will happen at once!
Oh, I had to just go and check on the lads one more time to see if it is possible Bazza has flown. Nope. It is an hour later and Bazza is still eating!!!!!!!! Bazza has been eating for two hours. I kid you not. Did someone get Little Bob mixed up with Big Bob?
Flying uses up a lot of calories. Look at the difference in size between Falkey and Bazza. Gracious.
Thank you for joining me. Take care everyone. See you soon.
Thank you to the Port Lincoln Osprey Project and Charles Sturt Falcon Cam and Cilla Kinross for their streaming cams where I took my screen shots.
In the first chapter of her book, Field Notes from an Unintentional Birder, Julia Zarankin talks about the rather spartan apartment she had as a graduate student. She talked about the compromises with her husband’s collection of 300 stone elephants only to realize what happened when she discovered birds. She said: “Within a year, the barometric pressure in my apartment shifted. Stuffed-animal squeaky hooded warblers learned to coexist with tigers; bird-shaped vases stood next to the elephant-shaped salt shaker; sculpted owls flirted with the faux-malachite elephant’s plastic tusks…more frightening: a pile of bird-themed stationary of every persuasion and a shelf dedicated to field guides…Not to mention the nondescript felt bird, the two paintings of birds, and the stained glass owl..” Later she adds the parrot notebooks, bird-themed t-shirts and all the bird magazine subscriptions. How many of us see ourselves in those same words?
I was, despite all of the warnings by Zarankin, delighted to see Emry Evans’s book, Monty, in the post along with some pins. The Dyfi online shop is now open. All of the nature centres will ship overseas. Roy Dennis’s Wildlife Fund has his three books and shipping internationally is calculated at check out. Lots of good things at all the on line shops for Osprey fans.
Emyr Evans writing is exceptional as are the images in Monty. Written with a deep, abiding love and respect for a bird – 50 stories from the pen of Emyr Evans.
It is a horribly grey day on the Canadian prairies. Will it snow or will it rain? Do birds get arthritis? Would they like a heated area to warm their little feet? Those are the silly thoughts that have gone through my head today.
Dyson decided it was best to just be off the snow altogether and sit in the tray feeder filling his cute little face.
Dyson doesn’t share. He is like Ervie, the Port Lincoln super star fledgling who grabbed the first fish of the morning from dad at 6:50:24. Oh, I love this image of Ervie in front of Dad grabbing that fish with his leg just like Mum does. Ervie watched and learned. Sorry, Bazza.
Falky just loves to fly and he was much more interested in checking out the area than the first fish. He flew in just a little too late.
Falky’s landings are actually really good. Ervie did a few spins yesterday and wound up landing on Bazza – Ervie needs landing training. That is great form that Falky has on this landing. Ah, the lads will all improve. This flying thing is just new. What fun it must be to whip around the bay!
Now Bazza – it is your turn!
Diamond brought prey in for Yurruga at 07:09. Yurruga was ready!
I thought Diamond would drop the prey and leave like Xavier but she had a different idea.
Diamond who incubated the two eggs during the night decided she was also going to feed her nestling.
Look carefully. Yurruga is changing. The white down is really coming off those wings and the head. She looks like a bird, not a fluffy column with a sort of bird head. Even, the fur boa is disappearing.
You can see the pin stripes on Yurruga’s chest and her head now looks like that of a falcon. Amazing. Equally impressive is the length of Yurruga’s tail. What a gorgeous Peregrine Falcon she is going to be.
Ah, and if you are watching the dates, Izzi fludged a year ago today. Izzi is the 2020 hatch of Diamond and Xavier and quite the character.
Oh, such delight. There is no news – at least not yet today – on Grinnell. I hope he is ready to be released shortly. And no news on WBSE 27 but there was a gorgeous Galah in the nest this morning poking about.
One of the Aussie chatters always said that if someone called you a ‘galah’ it meant that you were rather ‘slow, dim witted’. Ah, terrible. They are such incredibly beautiful pink and grey cockatoos. A few minutes of a cute bird that loves to have ‘tickle tickle’.
Bazza still has plenty of time to fly today but I don’t. Thank you for joining me — and if you loved Monty, you seriously need to get to the Dyfi store and get a signed copy of Emry’s book. I promise you will not be sorry but you will need a box of tissues. Take care. See you soon.

It was really difficult to keep up with the number of fish coming on the Port Lincoln Osprey nest yesterday but, everyone got something to eat. It does not appear that any of the brothers were left out and some, if not all, had two fish.
The winds picked up and the lads were all hunkered down at 18:57:22. It is often hard to tell what the weather is like just looking at the screen but it sure appears to be windy and later on the boys have some rain drops on their wings.
Dad is still out fishing for them. Ervie got the next fish delivery after being hunkered down. He was eating it at 19:49:37. Falky is hungry! Bazza is just watching.
Dad flew in with another fish at 20:22 and Falky got that one. So all the lads went to bed with some fish in their tummies. Dad, you are really amazing.
Bazza had a really nice fish at 14:03:54. He sure had to defend it. Ervie came flying in and the pair had a very short brotherly tussle but, Bazza maintained control. Good for you, Bazza!
It might have looked horrible watching it, these three have been so polite to one another. They may never have the competition for food some regions have but it is good to be able to protect your ‘fish’ and Bazza did a great job handling Ervie.
Bazza enjoying his fish in peace.
Today might just be the day that Bazza joins the skies with his brothers. I wish there were cameras all around the barge to watch them flying and having fun with one another!
The Audubon Society posted an interesting picture of an Osprey named Smedley. Some of you might know the story of Smedley. I didn’t and it is quite heart warming. Smedley fell out of his nest in 1998 and injured himself to the point that he would never be able to be released into the wild. He could not fly. He has remained at the Audubon Centre for Birds and Prey – count it – 23 years! His wing injury began to bother him and a sling was constructed so that he could move about comfortably.
There he is with his sling. What a wonderful story. Just heart warming. If you travel to the Audubon Centre for Birds of Prey in Maitland, Florida you might see Smedley. It is near Orlando.
One of the reasons this is such a heart-warming story is that many Osprey do not do well in care. Smedley is certainly the exception and maybe a look back at what – in particular – the rehabbers did when he arrived could help improve the success rate of Ospreys going into care now.
The Bald Eagles continue to work on their nests. Harriet was hit very hard by the GHOW that has a nest near to hers and M15s’ in Fort Myers. This was a growing problem last year with both the adults and the eaglets. Yurruga continues to grow and develop her self-feeding. She is adorable. There is no news on WBSE 27’s release. One of my eagle friends tells me that the GHOWs have been to visit the nest in Farmer Derek’s field but there is a problem – the raccoons have dug a hole in thee nest. She suggests that he get a raccoon baffle – great idea! Funny thing. We all loved watching those owls hatch and grow but my goodness they can kill everything in sight – and do.
Take care everyone. If I see Bazza fledge I will let you know. If I miss it – let me know. Thank you for joining me today.
Thank you to Port Lincoln Osprey Project for their streaming cam where I took my screen captures and to the FB page of the Audubon Centre for Birds of Prey where I grabbed that image of Smedley.
It is difficult to try and describe the weather we have been having to someone who might never have experienced it. Someone took a video of the blowing snow on the highway, a huge buck, and some of the issues people face trying to drive on the road in a storm. When you cannot see the road for the blowing snow, we call it a ‘white out’. This is the time of year we also call ‘the rut’. The bucks dig and spray marking their territory. We are seeing many in the fields around the city and in larger treed forests within the City.
Ah, but I am not here to talk about the horrible winter weather we are having.
My last blog focused on Ervie, the third hatch at the Port Lincoln Osprey barge in South Australia. Ervie managed to get the first fish of the day. He only left the tail for Falky. To show how congenial these three are, Ervie did not even try to get the 10:48:28 delivery from Dad. Instead, Bazza (Big Bob) snatched it.
There he is enjoying his fish.
The camera is zoomed out in case one of the lads decides to fledge. Oh, I do hope they stay a little longer – another week, maybe.
Little Yurruga at the Charles Sturt University falcon scrape had 5 prey items for breakfast today. Yesterday was not a good day for feedings but, Diamond and Xavier have made up for it today. I am thinking that the parents might be teaching Yurruga that there are days with little food and some days with a lot.
Yurruga was really hungry when Xavier came with breakfast! Really hungry.
Yurruga has just finished that breakfast. Another prey item sits on the scrape, a Starling, and Xavier has brought more food. Notice that Yurruga is not running up and tackling Xavier to get the prey. Yurruga is probably wondering why there is so much food today.
Diamond came in to help Yurruga finish up that delivery. The Starling is still where it has been all morning. Diamond really dislikes Starlings!
Yurruga has an enormous crop. It isn’t her crop that interests me, however, but, the change in her plumage. Much of the fluff has disappeared. Peregrine Falcon juveniles have beautiful banded chests. Their bars are vertical. When Yurruga is an adult, the bars will be horizontal. Notice also the beautiful dark head and the tip of the wing. Oh, she is morphing right before our eyes into a very beautiful juvie.
She does not seem to be interested in the Starling that she pulled over to the rocks earlier. Oh, wait…maybe she is!
The feathers are almost off the left side of Yurruga’s head. Notice her beak. We get a chance to see how it has developed in this profile image. Yurruga is becoming very ‘falcon like’. Those chest feathers – that coppery brown – are just lovely. She looks like she has a feather boa around her neck – something she might need where I live today.
Oh, Yurruga means business. She is going to do something with that Starling.
She is showing us how strong she is! There are still some soft pantaloons but the down is coming off with every flap of those wings. Is there anything cuter than a little peregrine falcon at this stage in their development?
She is dragging that old bird back into the centre of the scrape.
There is our Peregrine Falcon with her large beak standing victorious on her prey. This pose really reveals how much Yurruga has grown. All of the feathers necessary for flight are growing in. Amazing.
Awww. Yurruga gave up on that old bird. No one seems to really want it. Wonder if Starlings have ‘Best Before’ dates on them?
WBSE 27 @Chris Bruce
If you missed it, here is the latest update on White Bellied Sea Eagle Fledgling 27, three days ago:
I wanted to bring you an update and some good news. The Port Lincoln Osplets are doing fine and I am certain that Falky will have a fish before the end of the day. Yurruga has already eaten enough to last her well into tomorrow. It also appears that WBSE27 is doing extremely well in care. The last update on Grinnell was on 10 November. He was getting to go into foster care for a few days before being released. All of the Kakapo are alive and the NZ DOC Rangers at Taiaroa Head will not decide which Royal Albatross couple will be on the Royal Cam until all eggs are laid.
Thank you. It is really nice that you are joining me. Take care wherever you are. Stay safe.
Thank you to the following for their streaming cams or FB news where I took my screen captures: the Port Lincoln Osprey Project, Sea Eagle Cam, Charles Sturt University Falcon Cam and Cilla Kinross.
The last update that we had on White-Belled Sea Eagle fledgling 27 was on 5 November. That was a week ago and despite the fact that it was not that many days, it was easy to get restless waiting for some news. I am delighted to bring you some really good news.
Here is the posting:
“An update on the progress of SE27 in care “The Sea Eagle is doing very well under veterinary care and will soon be released back into the wild in Newington Nature Reserve. It has been identified as a male. He is eating well and strengthening his wings in a flight aviary. “
Oh, we just needed some good news. This is fantastic. Others were out and about today and there is still no sighting of WBSE 28.
Oh, there was such excitement yesterday. The Port Lincoln chicks were banded and, in addition, there were rumours that 3 or 4 of the Melbourne eyases had fledged. Let’s put that rumour to bed. Mum is sleeping on the weather protector above the four. So everyone is still home. That is fantastic. Maybe they will all fledge from this end so we can see!!! Ironically, Victor Hurley said they would turn the camera around to face the other direction after his Q & A session so there was a better chance to see them fledge. With two ends and one camera, it is very difficult to predict which end will prove to be ‘the one’.
Port Lincoln wanted to band a male chick because they wanted to compare his dispersal to that of the female, Solly, who fledged last year from the PL nest and has a tracker. Solly has taught osprey researchers much including the distances that female osprey will disperse. In Solly’s case, she traveled 311 km to Eba Anchorage. There were rumours that osplet 2, Middle Bob, was to get the tracker because it was thought he was the only male. In the end, Port Lincoln had three males to choose from and they went with the one who weighed the most – Little Bob – who turns out to be the ‘biggest’ Bob.
Here are the names and weights:
Big Bob, first hatch, has a red band, weighed the least at 1280 grams and is named Bazza. The name celebrates Take 2 Photography’s husband, Barry Hockaday, who did so much to bring the Osprey Barge to a reality.
Middle Bob, second hatch, has a yellow band, weighed 1330 grams and is named Falky after Ian Falkenberg, the bander.
Little Bob, third hatch, has a dark green almost black band, weighed 1380 grams and is named Ervie. It is the name of the Scottish town where Australia’s current Minister of the Environment grew up. This choice focused on the fact that the growth in the Eastern Osprey population and this project would not be possible without the Minister’s support.
And that is how ‘never miss a meal Little Bob’ became the biggest Bob! And got the sat-pak! Well done, Ervie.
The chicks behaved as expected. When the boat came close they pancaked so much you could not see them above the nest. Each was removed and put in a small sack. There was no stress at all. A gift of fish was put in the nest. The parents returned within minutes of the chicks being put back in the nest. It was a beautiful process and so much will be learned through the monitoring of Ervie’s travels including dispersal and threats. I will not deny that I am a huge supporter of banding and tracking. It is the only way to learn where the birds go, where they breed, what dangers there are in the environment, what happens to them, etc.
I admit to being very tired this morning. I could not stay awake long enough to find out the names last night or, should I say I stopped waiting at 2 am in Canada. It was so nice to run to the computer and see all the information this morning.
Many wondered how they could donate to keep the cam running at Port Lincoln. It is complicated and it is my understanding that they cannot accept donations. That said, if you or someone you know is going to the area why not take one of Calypso Star’s nature tours? Go out to see the sea lions or get in a cage and watch sharks. That would be a great way to thank them.
Update on WBSE 27 on 5 November (in case you missed it): “SE27 is doing well, gaining in strength and is feeding by itself. It has moved to a larger raptor cage to allow it to exercise and recover. The treating vets have advised that SE27 will be in care for a few weeks while it recovers and will be released back into the wild as soon as it’s well enough. Healing takes time so please be patient. Updates will follow when possible.”
It is another gorgeous day on the Canadian prairies. 13 degrees C. The sun is bright and I can see the squirrels already hoping that their breakfast will be taken out to the deck. They are a little early.
Take care everyone. Thank you so much for joining me today. See you soon.

Annie only knows Grinnell is not there and it appears she might be taking up with the interloper that caused Grinnell’s injuries. My goodness!
The birds are stirring at Port Lincoln this morning. Before 6am there was calling from the nest. There were only 3 birds but it was Mum calling Dad with the breakfast order. No. It was the chicks calling Dad wanting their fish! They are so big. Ready to begin flying.
Just look at those three birds. I sure hope they stay in the nest and pancake when they are to be ringed today but I am worried the sound of the motor boat is going to make them bolt off the nest early. I so want to be proven wrong, for the sake of the birds, and foolish for even thinking such a thing.
Janet Forster says they will come in a boat and dingy when the boat gets back from the Sea Lion Tour. Fingers crossed. We will not be able to see this live but I am hoping either pictures or a video will be shared later. The trio were fed six times yesterday. It should have been seven but dad lost a fish and he found it and decided he would eat the entire thing!
Is this to be the day that at least one of the 367 Collins Street Four fledges? They slept on the ledge last night. Will they fly off together?
Yurruga had a lot of prey items yesterday. She sported a nice crop and is doing really well with her self-feeding. What a lovely independent eyas. In one instance, Xavier came in with a Rosella. Even with a crop Yurruga seemed to want to have some of it – they must be very tasty. Someone told me they are the equivalent to the pigeons in the city – parrots everywhere – but I have no idea if that is true. In the end, watch and see what happens. Oh, and before I forget. Diamond’s limp is still there but it is improving every day.
There is an updating on WBSE 27 by Judy Harrington. This is what she posted: “SE27 is doing well, gaining strength and is feeding by itself. It has moved to a larger raptor cage to allow it to exercise and recover. The treating vets have advised that SE27 will be in care for a few weeks while it recovers and will be released back into the wild as soon as it’s well enough. Healing takes time so please be patient. Updates will follow when possible. BTW, we hear fish and mice have been on the menu! It is unlikely any photos will be issued while in captivity. There are no reported sightings of SE28.” That is good news for this beautiful sea eaglet, WBSE 27.
It is really windy down in Ft Myers, Florida. M15 has been bringing his mate, Harriet, some nice treats in the last few days. The other day it was a Cattle Egret. She was delighted. The pair continue to work on their nest. Wonder when the first egg will appear?
Harriet being blown a bit by the wind. 6 November 2021
It is stormy over in Jacksonville, Florida. Still Samson and Gabby were both on the nest in the wind and rain preparing it for this season. Oh, goodness, this couple just warms my heart! (Yes, we all have our favourites. I admit it).
The weather out in Colorado is perfect and the Bald Eagle couple on the Fort St. Vrain Bald Eagle Nest are busy working, too. Last year they raised one chick. Wonder if they will make it two this year?
There is one eagle, at this very moment, working on the nest in the Kisatchie National Forest. I do not know if it is Anna or Louis. This is their second season together. So glad to see the couple returned. Last year was the first since 2013 that an eaglet had hatched and fledged in this nest. Nice to see the young family here. That is a great image on the two cameras and the sound is excellent this year. Cody and Steve have really been working on the set up. (Thank you!)
I am afraid that I could go on checking Bald Eagle nests and we would see the same image – one or both adults working on the nest. The eagles have really come back from nearly being wiped out. I hope there are enough big trees for them for nests!
It is going to be awhile til the PLO chicks are ringed and, believe it or not, it is 14 degrees C on the Canadian Prairies. Summer weather. Well, this is what our summers used to be like: 14-17 degrees C. Now you can double that. The sun is shining, the sky is blue, and so far, Dyson is leaving Mr Blue Jay’s corn cob alone. It is a great day for a walk. See you later. Take care everyone.

There is an update on WBSE 27 but, first, some background for those that do not know what happened. White-Bellied Sea Eaglet 27 had a forced fledge. The Pied Currawong were attacking 27 who was alone in the nest after WBSE 28’s fludge. 27 flew to the camera tree and then was, more or less, escorted out of the forest by the Currawong. A few days later, 27 was spotted. It was on some pavement. When it flew up, the Currawong began to attack its head. 27 fell to the ground. Thankfully help was at hand! WBSE 27 was taken into care and checked. Luckily there was nothing broken. The latest news is promising. I do really hope they will keep 27 til it is a very strong flyer. Maybe we will also find out if 27 is a male or a female.
This is the latest update this morning from Judy Harrington: “SE27 is doing well, gaining in strength and is feeding by itself. It has moved to a larger raptor cage to allow it exercise and recover. The treating vets have advised that SE27 will be in care for a few weeks while it recovers and will be released back into the wild as soon as it’s well enough.

Oh, it is so good to hear that 27 is improving.

There is a lot of discussion and concern for Grinnell, the mate of Annie, at the Campanile on the grounds of UC-Berkeley in San Francisco. An undergraduate student wrote a great article on the falcon family for The Bay News. I was excited when I read it because it mentions Holly Parsons, who runs the FB group for Xavier and Diamond on the Charles Sturt Campus, and the Manitoba Peregrine Recovery Project in the city where I live and the City’s 19 year old female falcon, Princess. The article is really informative. What a good writer this undergraduate is. Have a read:
I was hoping to have an image of the Spotted Eagle Owlet in Joburg back in the nest but it isn’t there.
In fact, the Mum has just noticed that one of the babies is out of the nest box. You can see its fluffy head under the Mum’s left leg. Poor little thing. It must be scared and hungry. I understood that someone was to place it back in the nest box. Hopefully this will happen soon.
Xavier flew in with a Starling to the Peregrine Falcon scrape on the campus of Charles Sturt University in Orange. Yurruga had been waiting and watching!
Yurruga spends a lot of time looking at the world outside the scrape. She is 28 days old today.
Here comes Xavier with a freshly caught Starling. Yurruga is so excited!
Dad can hardly get the bird into the scrape.
Yurruga is tugging and pulling.
Xavier looks like he really wants Diamond to fly in and feed Yurruga.
Yurruga reaches up and bites Dad’s beak. Look at how big ‘she’ is! Notice also that the down is coming off from around Yurruga’s eyes. She will look like she is wearing goggles tomorrow. Yurruga is right on track in the transitioning from the down to her juvenile feathers.
Xavier cannot prepare the Starling with Yurruga wanting to eat ‘now’.
He opens up the bird and feeds Yurruga some of the nice meat.
Then he flies out of the scrape with the remainder of the bird. He will either put it in storage for later or eat it himself or give it to Diamond. Clearly Yurruga is very healthy and doing quite well. It is nice to see Xavier feeding the little one. Maybe Diamond needs to rest her leg. No doubt Yurruga will have a couple more feedings today. Fingers crossed. She needs all the lunch she can hold.
At the Port Lincoln Osprey barge, Dad brought in a fish tail. Little Bob got it and Big Bob tried to take it. No real tussle and it looked like Little Bob was able to keep it. Just look at the strong mantling (putting wings over prey to protect it from being stolen). These three are going to be a handful to band on Monday!
Despite the mantling, the chicks definitely were remaining civil. This was not a real tussle for food.
Good practice for the future. Dad is so cute. He acts like he isn’t paying attention but he is. These parents are watching everything the three of them do. Everything is about being able to survive in the real world. They have done an amazing job.
Friday has started out pretty good. I hope it continues that way. Diamond is healing but still a bruise on her foot. 27 is improving and so is Grinnell. Yarruga is growing like a bad weed and soon will be bigger than Xavier. There are still four falcons at 367 Collins Street and it is hoped that someone will put the owl back in the box – again.
Thank you for joining me. Take care everyone and have a great day.
Thank you to the following for their streaming cams where I took my screenshots: Port Lincoln Osprey Project, Charles Sturt University Falcon Cam and Cilla Kinross, EcoSolutions JoBurg Owl Cam, and the Sea Eagles FB Page for the image of 27.
I know that some of you have watched birds fall out of nests including Silo Chick at Patuxent River Park last summer. Remember that feeling when you saw that little osplet fall into the water, heard the splash, and saw the others looking down? Felt helpless? Of course. Thankfully that story ended well. I have no idea how many called but the osprey was located and literally tossed back into the nest. It was an enormous relief. Others are not so lucky.
I posted a new owl box streaming cam in Joburg, South Africa just the other day. An orphaned Spotted Eagle owl was put in the box with two other owlets. The mother accepted it! Fantastic. The adopted owl is 5 days older than the other two and it got curious about the outside world today and fell out of the nest box!
What no one knew, at the time, was that the owl landed on a huge platform under the box. If it doesn’t get back into the box on its own, it will be placed back inside the box. Relief.
Yarruga was starving this morning. There were two prey deliveries at the scrape box and there was not a scrap left of either meal.
Yarruga was so excited when the second meal appeared that she could not stand still to eat. She literally ran around the scrape box as in the images below.
Xavier was certainly glad when that feeding was over! There is not a drop left for either of the adults. Yarruga was soooooo hungry after having only 2 feedings yesterday. She does love her food! And she is certainly growing. Look how big she is next to Xavier!
In fact, Yarruga should have had a nice tasty little duckling yesterday but Diamond saw it and quickly took it from Zavier and flew out of the scrape! One has to imagine that this is quite the delicacy (as opposed to the dreaded Starling!). After her injury, I am actually glad that she got it.
Port Lincoln did a nice close up of the juvenile feathering of the three osplets this morning. Just look at the variations in the depth of the white juvenile feather banding. Little bob is in the middle.
As the dominant bird, Little Bob often gets the first bite. She is full and letting the other two have their turns as she looks out to the water in the image below. Of course, I am saying ‘she’ because of her thick legs. Wait til Monday when the banders declare she is a he. How funny! Whatever gender, that bird is gorgeous and I will continue to celebrate the times that she put Big Bob in his place.
There she is below.
Victor Hurley, the main researcher for the Peregrine Falcons in Victoria has been posting information on the 367 Collins Street FB Page. The last posting was on ‘Dispersal’ because, as we know, the falcons will be fledging shortly. I imagine that there are many things in this column that would be of interest to many of you. This is what he wrote:
First Flight Normally, this is not such a serious undertaking as that from an inner city high rise ledge. Normally pre-fledgling Peregrine Falcons will scramble around across their natal cliff for quite some time before taking their first flight. Mostly this is successful and they land high on another ledge or small perch. In a city location they will land on the roof top of another building nearby. If the winds are tricky then things can go south pretty quickly. Once they have mastered their first flight then they will spend increasing time “on the wing” and following and learning from the parents how to hunt. As soon as each youngster achieves their first kill the adults (parents) will stop providing any more food and that youngster is on their own to find food. Once all young are successfully hunting then depending upon the experience and ruthlessness of the adults they will all be chased with serious determination out of the territory altogether. In some cases this may occur in December or even early the nest year. Either way the young tend not to return again to the nest ledge that we have been observing. Maybe occasionally, but then only briefly.
Plumage differencesLeading up to this first flight the adults restrict the level of food resources they bring to the nest. This explains the weight loss of the nestlings. The wings of the nestlings are still growing but they are also losing weight. This makes them lighter with larger wings which provides for a “lower wing loading” which makes their first flight easier. Neat, huh! The other point I thought I would raise here is that of the plumage differences. Peregrine Falcons as with most raptors and many other bird species have a juvenile plumage phase and an adult plumage phase. The juveniles are in essence a brownish colour with vertical splotchy stripes over a “dark milk tea” fawn base colour on the front and dark brown wing, back and head. Whereas the adults have a near black hood for the head, slatey grey wings and back with a soft cream bib and base colour overlayed with fine dark grey-black horizontal stripes. The tail and main wing flight feathers are also longer in the juveniles and they moult shorter feathers with each year as they get older.
Natal dispersal This is the ultimate question. Where and how far do Peregrines disperse to find a place of their own in which to breed. Natal dispersal is the distance (and direction for those interested) in how far fledgling Peregrine Falcons ultimately move to find and establish (read take over for the most part) their own breeding site. Amongst Peregrine Falcons in Victoria, as with most bird species the world over, the females disperse further from their fledging site to breeding site then do males. Based on observing 127 breeding adults with leg bands (placed on them as nestlings) the females dispersed on average 64km (range 6-280km) and males average 25km (rang 1.6-90km). This differing dispersal distance minimises the likelihood of siblings interbreeding. The average age at first breeding is as follows: females 2.6 years (average) and for males 3.3 years (average). Another way of presenting this same data includes presenting the direction as well as the distance males and females disperse. No bias in dispersal direction was recorded.Victoria is a relatively flat area of the planet, its highest point above sea level is Mt Bogong (1,979m) and~80% of Victoria is <200m ASL. So for a predatory species like the Peregrine Falcon that doesn’t migrate annually due to milder winters and having the highest wing loading of any Peregrine sub-species globally, in a state (Victoria) with limited high altitude cliff faces with an abundance of low lying wetlands and associated birdlife and a very diverse range of parrot species what is a cliff nesting raptor to do? A look at all (256) of the Peregrine Falcon nests ever described in Victoria provides the answer to this question. The Peregrine Falcon in Victoria has overcome these obstacles by adopting a range of novel nesting situations (by nesting in stick nests of other birds, tree hollows and of course buildings (a growing trend globally). So this leads to another interesting question. Do those birds raised in one type of nest only adopt others of the same “nest type”? or will they readily disperse to a different type? That is to say, do they become behaviourally “imprinted” on the nest type they are raised on? Again thanks to the long term banding of nestlings and resighting of adults (with telescopes) by volunteers with the Victorian Peregrine Project the natal dispersal patterns of 127 Peregrine Falcons have been identified so far showing that 30.2% have adopted a different (novel) nest type from the one they were hatched and raised in. Between the sexes dispersal patterns are similar with 26% of females and 23% of males adopting different or “novel” nests in which to breed. Combined 30.2% of Peregrines undertake novel natal dispersals to find a place to breed. So the myth of nest type imprinting has been pretty thoroughly exploded with these bird banding results.Further to this, slightly counter-intuitively, novel dispersal events (dispersing from one nest ‘type’ to another) were less dispersive with no sex bias. That is those individuals who adopted a ‘novel’ nest type did so by dispersing a shorter distance on average than those undertaking a typical natal dispersal. Presumably they are doing this in order to exploit a familiar (geographically closer) food/prey resource by adopting a novel nest type in order to remain close by to that prey resource.So back in 1991 when Peregrine Falcons were first identified breeding at 367 Collins Street, Melbourne it was one of only two or three nest sites on built structures that were known. Since then over 20 new sites have been discovered and the number continues to grow. Nest site selection is driven by its proximity to food resources as well as the security (from predators and human disturbance) and how protected the nest is from rainfall and water runoff.Surviving the first two years…The third question (although not chronologically) is what is the survivorship of young Peregrine Falcons in their first two years prior to breeding. Generally, it is accepted that there is a ~a 66% die-off of Peregrine Falcons within their first year. Given the youngest breeding is at two years post hatching I have trawled the VPP database again to investigate causes of mortality of ~240 banded Peregrine Falcons in their first two years post banding. Most banding occurred at or around 24 days post hatching. When considering the various incidents there was no sex bias. That is neither sex is more prone to any cause of death compared to the other. Rock falls, cliff collapses or storms bringing down trees or stick nests have been a surprisingly regular threat to young of this species. The constant and ever present shooting of Peregrine Falcons continues to this day. The first ever band recovery of a Peregrine Falcon in Australia was in 1958 in Victoria. Disease of course is Trichomoniasis and predators varies from Red Foxes, Brown Falcons and even Peregrine Falcons in limited circumstances. Secondary poisoning has generally been a result of pigeon control campaigns.”
This information would, in general, apply to all falcon populations. And if you read all that – it is a ‘Double Whew’ for today. I have been reminded that Victoria Hurley is doing a Q & A tomorrow. I cannot find the link to it. If I do I will send it out later.
Thank you for joining me. Everyone has been fed at least once if not twice already. Diamond is looking much better. No news on WBSE 27 yet and nothing on Grinnell. Take care!
Thank you to the following for their streaming cams where I took my screen captures: Port Lincoln Osprey Project and Charles Sturt University Falcon Cam and Cilla Kinross.
Diamond is the female at the Charles Sturt University Peregrine Falcon scrape box on the University’s water tower. Her mate is Xavier and their only chick this season is Yarruga. Yarruga is 27 days old today. Its name means ‘Sunny’ in Maori.
Several days ago Diamond injured herself, probably in a hunting incident. Her right wing was a bit droopy and she continues to have difficulty putting all of her weight on her right foot. Her mate, Xavier, has often taken over the feeding duties of Yarruga because feeding requires putting pressure on the feet to hold the prey and pull up to get the bites off for the chick.
Yarruga was particularly hungry this afternoon. Diamond was on the ledge of the scrape watching over her baby, trying to get some sleep, and also attempting to keep the weight off the right leg.
Instead of writing how Diamond is doing, I thought it was just best to take a few video clips so you can see for yourself. They do say a picture is worth a 1000 words.
Here is the first one. Diamond has been resting on the ledge of the scrape. She has kept her right leg slightly elevated and has been able to sleep some. Yarruga is hungry and, since this is the big growth spurt for Yarruga, she sees a parent and thinks it is dinner time. Poor Diamond. Yarruga is prey begging.
Xavier brings in the Starling that was left over from an earlier feeding. The falcons have a place where they stash food. It is a great idea. They never waste a single bit of the prey they kill for food. (We could all take a lesson from them!). Diamond wants to feed Yarruga. The following two clips are from later in the feeding.
The feeding went on for some time. This is the last bit of where Diamond finishes feeding Yarruga and then flies off with the rest of the Starling. Despite the fact that she doesn’t like Starling (prefers pigeons and parrots), it would not be easy for her to hunt now while she is healing so she will happily eat the Starling leftovers.
It still appears that Diamond is in a lot of pain. She is really limping but her wing appears to be better. It must be difficult because she wants to take care of her baby. I think that is why I actually believe she is improving. She could have flown out and let Xavier feed Yarruga but she chose to do it herself. It is going to take some time for her to heal and we need to continue to send her our best and most positive wishes.
A quick glance at other nest news:
The 367 Collins Street ‘Four’ decided to run along the gutter and let us have some really good glimpses of how they are growing and changing today. Remember when you look at them that they are precisely one week older than Yarruga. It is hard to imagine that they were mostly covered with white down a week ago! Here they are wanting to fly – and way too soon, they will.
The down is really coming off. They are so curious about the world outside of the scrape. Mum and Dad have been doing aerial demonstrations for them. This is something that the adults do to try and entice the eyases to fledge.
The Port Lincoln Osplets will be banded, named, and at least one will get a sat-pak on Monday 8 November, Australian time. Remember! It is possible that we will only get to see the event on tape. It is exciting. I cannot wait to see if Little Bob is a female with those thick stubby legs!
Just look at the size of Dad’s wing. Together they would be wider than the nest! He is bringing in the second fish of the day. Now when Mum begins calling the chicks join in. It is really sweet.
Mum is so quick to pull that fish off Dad’s talons. I often wonder if the males ever get injured when this happens.
Today, Little Bob is more interested in watching Dad go down to his man cave on the deck of the barge than being first in line to eat. That is almost shocking.
The trio are pancaked. They have eaten so much. Mum brought another fish in at 13:50 – their third of the day. On average, the osplets have 7 feedings a day so far. Fantastic parents. Can’t say enough good things about how well they have worked together this season.
There has been no new updates on WBSE 27 since 1 November, Australian time. When I hear anything, I will let you know.
Thank you for joining me and checking in to see how Diamond is progressing. We just have to be patient – and that is hard when we see her in pain. Take care everyone. See you soon.
