Rain and blowing winds

It’s raining outside. The sky is a heavy grey and the flame willow’s bark is a bright reddish-orange in this light. It is gorgeous. But where are the robins who should be pulling worms from the soil around the flame tree? They are no where to be seen. And the Dark eyed Juncos have not arrived en masse either. We wait.

The branches turn green in the summer but in the winter the Flame Willow is a bright red-orange.

There is no life in the dreary damp garden except for two BlueJays flitting about. In half an hour it will fill up just when the feeders are being replenished. Sometimes I think the sparrows have an alarm clock set – they are that punctual.

The last couple of days there has been a sadness hanging over the Bald Eagle community. Indeed, it hangs heavy today just like the grey drizzly skies that surround me. Jackie and Shadow on the Big Bear Bald Eagle nest in Big Bear, California lost their first clutch this year. Their nest is about 44 metres or 145 feet up in a Jeffrey pine tree with a view of Big Bear Lake. It is incredibly beautiful. Jackie is thought to be nine years old and Shadow is around seven; neither are banded and both so want to be parents. A Raven ate their first egg and the second broke. They tried again. Sadly, the first chick died during hatch as thousands of people watched anxiously along with Jackie and Shadow on 18 March. They could hear its chirping and must have been so excited. The second egg is now 38 days old. The normal for BE hatch is 35. Last year they incubated their eggs for sixty days and when they finally stopped the ravens came – the eggs were empty.

So we hope and wait. I really hope – beyond hope – for this nest to be successful this year.

And, of course, there are the on going issues related to the Great Horned Owls and Harriet and M15 on the Pritchett Farm in Fort Myers, Florida. The GHOW nest is 274 metres or .1 of a mile away from the eagle’s nest. This has caused nothing but undue problems for the eagles this year. Last night’s attack was one of the worst. The GHOW knocked Harriet off the branch and into the nest but a then off the nes! You can hear the cries.

Lady Hawk’s video shows this from several angles. You can watch the first and get the idea.

Eagle and Great Horn Owl populations have recovered since the time of DDT. Now, there are several issues both related to human activity – the loss of habitat -meaning space – and also the lack of trees adequate for nests that impact the lives of both. There is more and more competition for resources.

E17 and E18 are both self-feeding and they really are the best of buddies. Twins born within hours of one another. E18 might be the Queen of Mantling but both still love to be fed by their parents. They are so big. One of the best ways of telling which is which is if you can see the tip of the tails. The one with a white band, on the left, is E18.

For those who worry about aggressive behaviours, it is now easy to forget that many were horrified at the bopping E17 gave 18. E17 even had to go into time out at CROW clinic! It all evened out. E18 grew and became not so intimidated. That is a good thing. They will hopefully both thrive in the wild. As Sharon Dunne (aka Lady Hawk) reminded many on one of her videos yesterday, if the birds cannot survive in the nest being fed by parents they will never be able to survive in the wild. As it stands, less than half the bald eagles that fledge live to see their first birthday.

Look close. The white band is on the eaglet on the left. That is E18 with E17 on the right.

I continue to tell people that GHOWs are fierce competitors and they are dangerous. There is nothing cuddly about them! Speaking about Great Horned Owls and Bald Eagles, the two owlets of Bonnie and Clyde are really growing. The oldest is always ready to try and hork down the mouse that Clyde delivers. In this early morning shot, you can see Clyde, Bonnie, and one of the eaglets. Everyone is doing fine on that nest. Only time will tell if the owls become permanent occupants of what was a Bald Eagle nest.

The daughters of Farmer Derek named the owlets Tiger (the eldest) and Lily (the youngest). In the image below Clyde is on the left, Bonnie is in the back and if you squint you can see one of the owlets, probably Tiger, in the nest. Sweet names. I wonder if they knew that GHOWs are sometimes called ‘Tiger’ owls?

21 March 2021. Clyde, Harriet, and one of the owlets.

The young father, Harry, is incubating the two eggs on the Bald Eagle nest at the Minnesota DNR. You can tell it is Harry and not Nancy because of the dark patch at the end of his beak. Remember – this young father has not fully changed to his adult colouring – he is only four years old! That tree is really twisting and the wind is howling and blowing. Those eagles have had all kinds of weather to contend with, too. But now we should be thinking about a pip! Their second egg was laid at 2:54 pm on 20 February with the first on the 18th. That means that egg 1 is 31 days old. If the rule of 32 days for a hatch applies this young father should be getting excited. I hope that the weather smartens up for them and they have a successful hatch!

The rain and the wind that is keeping the Minnesota nest soaked and twisting left the Bald Eagle nest in Jacksonville soaked as well. Gabby did a great job of keeping Legacy covered up and Samson even brought in provisions during the windy storm.

One of the things you will no longer see on the NE Florida eagle nest is ‘eggie’. Samson came in on the 17th of March and while Legacy was self-feeding, he aerated the nest. As he was punching holes in the base of the nest cup, Samson kept checking that Legacy was busy eating. Then he buried ‘Eggie’ in one of the holes and covered it with Spanish Moss. There seem to be no adverse effects. Some of us thought we would have to strap a backpack on Legacy so she could take Eggie and pinecone with her when she fledges. It’s hard to believe that it was not so long ago when Legacy had Avian Pox. She survived it well. In the image below Gabby has brought in a fish for Legacy. Legacy mantles and feeds herself. ‘Look, I am all grown up, Mom!’ They are all growing way too fast.

21 March 2021. Legacy is self feeding.

And the rest of Bird World seems to be in a holding pattern today. The trio at the Achieva Osprey nest have been fed. They all had good full crops last night and there was not so much commotion this morning when the first fish was brought in at 7:59.

21 March 2021 From left to right: 2, Brutus, Tiny Tot

The people on chat have named the eldest Brutus because of the way that it treats the other two. And, Brutus, was particularly nasty to both Tiny Tot and 2 last evening. Still, they got food and that was really what mattered. Brutus has not been able to stifle their will to survive. You can see all three of them standing up to be fed this morning. I did do a wee bit of a giggle. For many, Brutus is a male name and is associated with male aggression since the time when Marcus Junius Brutus was one of Julius Cesar’s assassins. In this instance, it is, however, highly likely that Brutus is a big female. Watching the Port Lincoln Osprey cam showed me that like GHOWs, you do not mess with a big female Osprey when she is upset. Best to just stay away.

Big and Li’l are doing fine on the Duke Farms Bald Eagle nest. Both of them had a nice crop this morning. There was even a tandem feeding with Mom and Dad.

21 March 2021. Both parents feeding at Duke Farms eagle nest.

Someone remarked at how big Li’l is getting – that is what happens when you get enough food, you grow!

And last but never least – the ‘Brutus’ of the Port Lincoln Osprey nest, Solly, is thriving. She is 183 days old today and she has mustered the strength and the courage to cross the entire bay at Streaky Bay. Well done, Solly!

Thanks for coming to check all the characters in Bird World today. The birds bring us so much joy – and sadness, sometimes. And, yes, uneasiness when we worry about them. Most of us sleep better when we know they have had a good meal. So today, let us send warm wishes for Jackie and Shadow – maybe a miracle will happen. It is too bad we can’t slip an orphaned baby eaglet in their nest for them. I am sure they would adore it.And let’s begin to get excited for the young father up in Minnesota. I hope it is a nice warm day tomorrow for their hatch.

And thank you to Port Lincoln Osprey and their Satellite Tracker, the streaming cams from Duke Farms, Achieva Osprey, NE Florida Eagle Cam and the AEF, SW Florida Eagle Cam and D Pritchett, Farmer Derek, the Minnesota DNR, and Big Bear Eagle cam.

Stormz

When I woke up this morning, this was the weather forecast that caught my attention. I sat and stared. Yes, the Achieva Osprey Nest in St. Petersburg, the SWFL Eagle Nest in Fort Myers, and the NEFL Eagle Nest in Jacksonville were all in the ‘possible threat’ of a Severe Threat region. What precisely does that mean? If it’s bad it is going to be really bad but, it might not be nothing at all?

At the Osprey nest in St. Pete’s, it was already starting to get a little gusty. Still, Jack came in with a really nice fish around 9:09 and all had a good breakfast – all of them were fed equal – and there was no issues of the eldest trying to be dominant. Great planning, Jack! It was, however, not long until the local weather report had warnings of rip tides (dangerous currents) and by 10:30 the nest platform was swaying pretty good. The local weather said 48 kph or 30 mph winds. It is hard to understand what that means to the nest structure and the Ospreys. I have presumed that the structure was built to withstand a hurricane but that might not be true at all. But what kind of a gust does it take to blow an Osprey or a little one off the nest? My mind quickly went back to the wind gusts that sent the Red Tail Hawk at Ithaca, New York, Big Red, flying off the nest bowl taking one of the eyases with her last year in the spring. That was really scary to watch. They both clamoured back onto the nest. Still, I sat and hoped that Tiny Tot would hold on good and tight. How much does the little thing weigh?

The image below does not capture the swaying of the nest. The rains had not started but, the gusts were strong. See how the little ones are all tucked in. It reminds me of ‘the duck and cover’ exercises when I was in grade school. If a nuclear bomb exploded, we were told to get under our desks and cover our heads – we would be safe. Don’t even get me started about that. However, those three little Ospreys are doing a great job of tucking in. They would have gotten an A from my first grade teacher, Mrs McReynolds.

In a couple of hours there was a break in the weather and the little ones were able to relax. You are looking at Tiny Tot on the left and the eldest on the right. Both are getting juvenile plumage – all the fluffy down is now gone. They have a grey matte down covering and the beautiful copper coloured feathers are coming on their heads. They have a white stripe from their heads down their backs. The dark lines from the back of their eyes to their neck are becoming prominent. They sure resemble dinosaurs when they are all tangled up together! Their crops have dropped so both are ready for a good meal. Let’s hope Jack has some success fishing. I am going to imagine that fishing could be difficult with the rain, winds, and rip tides.

Within an hour, the weather changed again. The winds picked up giving Diane a brand new hair do and the little ones are holding on under her wings. Good thing. The skies open and heavy rain comes down soaking everyone and the nest.

It has been a difficult week for food on this nest. The high temperatures, reaching as much as 30 degrees C, have meant that the fishing was only good in the early mornings and around sun down. Despite the rain and the rip tides today, Jack did manage to bring in another fish -quite small – after the weather had settled for a bit, around 7:26pm.

The oldest dominated the feeding and treated both number 2 and Tiny Tot (some call him Tumbleweed) rather aggressively. The kids are wet and cold and miserable – and I imagine Diane is, too. These are experienced parents who have fledged three off a nest. They know what they are doing but they cannot control the weather – the storms or the high heat. Let’s just hope that tomorrow is a cool calm day with a couple of big fish on the nest!

The issues with the eldest on the Achieva Osprey Nest happen over and over again on Osprey and Bald Eagle nests around the world (as well as with other species). And the situation -the sibling rivalry -can turn on a dime. For the past few days there have been concerns about the aggressive behaviour of the eldest to the youngest at the Duke Farm nest in Hillsborough, New Jersey. The actions of the eldest got so bad that a message was posted by Duke Farms acknowledging that the behaviour being displayed was abnormally aggressive – ‘abnormally.’ The farm had obviously received e-mails and phone calls wanting an intervention to happen. Duke Farms had to remind watchers that the birds are protected and that their staff are not allowed within 305 metres or 1000 feet of the nest.

I have great sympathy for anyone watching the bashing that is given to the smaller ones. My whole body has gone rigid seeing a little one in submission unable to get any food – their heads pecked and their necks twisted by the eldest – when all they want is a few morsels of fish. And like many of you, I have watched these little ones perish, frustrated that no one took them off the nest and fed them so they got strong and could go back.

This morning the rain was coming down really hard. There was no food on the nest. The fish from yesterday was gone and the mother had picked every piece of meat off of the black feathered bird brought into the nest. At 12:59 the male flew to the nest and looked at the empty pantry. At 14:57:21 he returns with a trout from the stocked pond on the farm. Yes, like the nest for the SW Florida eagles on the Pritchett Farm, this one also has a fully stocked pond for the eagles.

Nest watchers were anticipating that the behaviour of the eldest was going to be very bad once prey arrived since there had been no food for twenty-four hours. That is, however, simply not what happened. The youngest stepped up to the front of the nest bowl and ate – and I mean ate! Not nibble – gorged on large chunks of fresh fish. It had so much confidence that it actually stole a bite of fish out of the eldest’s beak. This little one is smart. If it gets a chance it keeps its head down and then gets fed. Yesterday everything worked in its favour, too. The eldest ate first – as usual. Mom fed it from the black feathered bird picking anything off that she could find til it was full. Then she moved over to the fish. At first the little one was hesitant but, sensing that the eldest was not going to attack, it took a few bites and then climbed around and went up where its mother could more easily feed it. She filled that little eaglet with fresh fish. So, again, the little one is smart – in fact, they have to be to survive. And that is what all of this is about – survival.

Samson and Gabby watched the skies from the branches for a long time. If you look off in the distance the report for Jacksonville showed the worst of the storm coming in late, around 11pm nest time. Still the dark skies must have worried these experienced parents. It is always good to remember that the birds can sense the changes in the weather coming as good as any satellite system.

Gabby is sleeping close to Legacy. It is nearly 11pm. You can hear the winds on the camera’s microphone but the local weather says it is clear. Excellent news.

The weather forecast for these three nests calls for slightly cooler temperatures with sun or partly cloudy skies for Friday the 19th. Let us hope that lots of fish are on the menu! I should also add, since some of you might be wondering – the nest in Fort Myers is also fine. No weather issues!

Thank you so much for joining me today. Before I go, let’s close with a scap of Bonnie the Great Horned Owl. She is all fluffed up. What amazing plumage! She, once again, survived the snow and rain in Kansas. Her little ones still have their eyes closed but they were restless and one stuck its head up. They are doing fine. Clyde is a fantastic provider and the mice were coming to the nest despite the inclement weather!

Thank you to the Achieva Credit Union in St Petersburg, Florida; Duke Farms in Hillsborough, New Jersey; Derek the Farmer, and the AEF and NEFL Eagle Cam for their streaming cameras. That is where I took my scraps.

Owls, Eaglets, and Ospreys

Farmer Derek lives on the Klingenberg Farm near Newton, Kansas with his wife and daughters. His father and his three brothers are also working at the farm – it is a wonderful family endeavour. It is on this farm where the now famous hijacking of a Bald Eagle nest by a pair of Great Horned owls took place on 1 February. This family loved the eagles that lived on their land and were disappointed when the owls ousted them from their tree but now the entire family has embraced Bonnie and Clyde and their owlets. Farmer Derek’s father is going to build Great Horned Owls boxes for them this summer and we will see what happens. It is called Value Added Agriculture and Farmer Derek just gave an interview on a PBS Nova show called Market to Market. The interview begins with some chat about other things but most of it is focused on the owls. You can move the time forward or listen to it all, here:

Lots of the birds have been growing beyond belief and it is time to check in on some old friends. First off, Harriet and M15’s little ones (did I really say little?), E17 and E18. You might remember this image of little 18 in the striped donut towel and 17 having to have time out because she was so aggressive towards her sibling especially during feeding times.

E17 and E18 getting treated for AC at CROW, Fort Myers, Florida. @CROW FB

The image above shows the two little eagles at CROW. Aren’t they precious? Their eyes have been cleaned. They were crusty and covered over and permission was given by the USFWS to remove them for treatment. That was the first week in February. Their test results came back today and confirmed they had Avian Chlamydophilia psittaci or AC, for short. That is what CROW suspected based on their symptoms. It is a disease caused by a bacteria, Chlamydia psittacia. Birds catch it from other infected birds – dust, feather, droppings. The symptoms range from a cough, to the crusty eyes, or to sudden death. So glad that a system known to be so slow worked fast for these eaglets and that E17 and E18 were treated! The pair were at the clinic for five days, returned to the nest only when the bacterial infection was gone.

This is E17 and E18 being fed this morning, 16 March, some five weeks later. They now have juvenile plumage. The only way you can tell the two apart is that E18 has a white strip of feathers at the base of the tail. In the image below, E18 is in the middle and E17 is the farthest away.

Breakfast for E17 (left) and E18 (middle). 16 March 2021. @D Pritchett Eagle Cam

For a long time, E18 was the underdog but she quickly became the ‘Queen’ (or King) of the snatch and grab and grew big. When food is brought on the nest for self feeding, the majority of the time E18 mantles it and eats! Very capable and no longer intimidated. As is so often the case, if the little one survives they figure out ingenious ways to eat and they thrive. Lady Hawk (Sharon Dunne) did a video of a squirrel arriving three days ago and E18 mantling it and feeding. Here it is:

They have turned into such beautiful birds. Here they are looking out at the big world that will be theirs. They are now more than halfway to fledging.

Little Legacy isn’t so little anymore either. She has overcome, on her own, Avian Pox which is fantastic. She will be immune for the rest of her life. The image below is from a week ago. Legacy still had soft down on her head but her feet were getting large and she had quite the full crop. There were jokes about her on the Internet as being a big ‘pudgy’. Oh, the benefits of being the only eaglet in the nest!

This is Legacy this morning on the nest with her mother, Gabby, waiting for a food delivery. The fluffy dandelions on the top of her head are almost all gone and now instead of grey down she is almost 3/4 covered with her juvenile plumage. They grow sooooooo fast and she is very beautiful. She copies her mother working on the nest, incubating and rolling ‘Eggie’ and will, one day add to the legacy of her grandparents, Romeo and Juliet.

16 March 2021. Legacy (left) and her mother Gabby. NEFL Eagle Nest, Jacksonville, FL. @AEF and NEFL Eagle Cam

You might remember the female Bald Eagle encrusted in snow for most of the incubation period – that was the mom over at Duke Farms. Two of the three eggs hatched and those two are growing and growing. These kids have some very different meals than Legacy who eats mostly fish (a few mammals) and many times people are left guessing what the two had for dinner. Despite a lot of prey available, there is some concern for the second eaglet who is consistently pecked down by the older at feeding time. It is the reason that I cringe when I see three eggs. Sometimes two is more than enough – and there are definite advantages to being an ‘only’ eaglet or Osprey. Fingers crossed for this little one.

It is unclear to me what precipitates the feeling of food insecurity that results in siblicide. I have printed and read all of the academic material – it is sitting in front of me – and I am still baffled by which nests experience siblicide and which do not. Are there real predictors?

The little one at Duke Farms wanted to eat and the older one kept blocking it this morning.

So, the little one waited til the older one’s crop was ready to pop and finally got around to eat. Smart. Let us hope that this keeps up.

Yippee. Older going into a food coma. Little one eating. Well done. @Duke Farms Eagle Cam

Yesterday I gave the dad, Jack, a ‘beef’. He is the mate to Diane at the Achieva Osprey nest in St Petersburg. Those osplets hatched on the 7 and 9 of March. I fully expected when the fish did arrive that there could have been mayhem because it was so late in the day and it had been so hot but – it didn’t happen. And hats off to Jack (did he hear me screaming at him), he brought in another fish later. It is entirely understandable that it was so hot that the fish went deep in the water and Jack had to wait til it cooled off to fish. Everyone was full heading to sleep and this morning at 9:35 he brought in an early morning fish. Those Osplets lined up nicely for the meals and did not bother one another at all. They ate. So maybe I will take that beef back, Jack! These are the most well behaved siblings to one another.

16 March 2021. Breakfast for the trio. @Achieva Osprey Nest

I have included the image below because you now see the beautiful reddish-brown feathers coming in on the head of the osplet closest to the front.

And he isn’t an Owl, an eaglet, or an Osprey but Izzi, the juvenile Peregrine Falcon is the cutest thing on the planet. He is inside the scrape box of his parents, Diamond and Xavier (talk about beautiful parents) and many are wondering if Izzi will ever leave. Last fall, Izzi went to sleep on the ledge of the scrape box and fludged. He was returned to the box on top of a water town on the campus of Sturt University Orange Campus, Australia. The second fledge and he hit a window and was rescued by Cilla Kinross, the researcher, and taken for care. Five days later Cilla Kinross climbed the 170 stairs to return him to the scrape box where he successfully fledged for a third time some days later. Maybe he thinks this box is his? I guess we wait to find out. Izzi loves to look at himself in the camera!

Look at those eyes. Besides their stealth speed at aerial hunting, these little falcons are adorable. Seriously I could take him home!

So glad you could join me as we check in with some of our bird friends who have been a little ignored lately. Take care of yourself. See you soon!

Thank you to Derek the Farmer, SWFL, NEFL, Achieva, Duke Farms, and Cilla Kinross and Sturt University Orange Campus Australia for their streaming cams where I grabbed my scaps.

Everyone loves Richmond

There is a lot of chattering going on around the ‘bird’ world and the one common word that binds people in the United Kingdom with those in San Francisco and Australia is: Osprey. Every continent has Osprey – some more than others. Many of my friends adore them above any of the other feathered friends because they ‘eat fish’. They are sometimes called ‘sea eagles’ but do not confuse them with White-Bellied Sea Eagles. Totally different.

Note the beautiful yellow eye, the dark line from that eye to the neck and the hooked beak. Wikimedia Commons.

You will find Ospreys on every continent in the world except for Antarctica. And there is no missing them. They have very distinctive plumage that helps them with the glare off of the water when they are hunting. See that black line going from the beak over the eyes and to the back of the head? That will stop the glare from the water so that their great vision, three times that of a human, can help them spot the fish swimming below the surface. If you watch American football you might recall that the players put a black line under their eyes to stop glare – something learned from the Osprey! The soles of their feet are different than other raptors. They are very rough with tiny little barbs. If they were a person you might recommend they go to get a pedicure – that is how rough those soles are. That rough surface helps them to hang on to wet slippery fish that do not want to be an Osprey’s dinner. They have four toes like all other raptors but the Ospreys can do something that others can’t – they can swivel one of those front toes to the back to help hold on to those wiggly fish. Brilliant.

Ospreys are smaller than a Bald Eagle but bigger than the large hawks. They weight 1500-2000 grams (3-4 pounds). They are about 54-58 cm long (21.3-22.8 inches) with a wingspan of 150-180 cm (59 to 79 inches). Their head, throat, and body along with their legs are mostly white. They have black and white banded tail feathers and distinctive black and white wings that bend at the joint. Their beak is black and shaped like a very sharp hook. Their eyes are a beautiful, beautiful yellow.

Female Osprey are about 20-30% larger than the males. The females have a ‘necklace’ of feathers that is darker and more distinctive than the male.

Female in back, male in front. Note feathers at top of chest. Scap from Loch Arkaig FB Page.

Osprey’s have a distinctive dive and I do not have an image of it. Once they have spotted their prey, they bring their feet forward so they are even with their beak and then catch their prey feet first. They then latch on to the fish with those sharp talons. It is quite spectacular.

How large are the fish that the Osprey catch? The Osprey normally catches fish that are 15-30 cm in length (6-12 inches) and that weight less than 454 grams or a pound. The largest observed catch was 1250 grams or 2.5 pounds. Some researchers believe that they can easily carry up to half their weight.

Do Ospreys eat anything other than fish? The answer is actually yes. While the majority of their diet is fish, Osprey have been observed, on rare occasions, to eat other birds, voles, squirrels, muskrats, eels, and salamanders. Droughts really impact Osprey and their ability to thrive.

Note: Ospreys carry their fish with those amazing feet and talons. Wikimedia Commons.

The territory of an Osprey will be near a body of water – a lake, a river with lots of fish, along the shores of the oceans and seas. They build their nests off the ground to avoid predators. Originally, Ospreys made their nests in tall trees but, as you know, there is a shortage of structurally sound tall trees.

Those migrating to Canada have been known to make their nests on utility poles. Sadly, this is a huge problem because of electrocutions. So many died that petitions were sent to Manitoba Hydro, a public utility company. Near to Lake Winnipeg, that company began erecting nest platforms for the Osprey. Ospreys actually like human-made nests. It is said that if you provide a nest, the sea hawks will come. And many in Scotland will tell you that is true! Ospreys are loyal and generally return to the same nest year after year.

During the winter, Ospreys head to warmer climates returning to their breeding grounds in spring. Ospreys from the United Kingdom migrate to The Gambia or Senegal with some juveniles known to stay around the coastal areas of Spain. Ospreys from North America migrate to the southern parts of the United States along the Gulf of Mexico, Southern California, the coasts of Mexico and countries of Central America. Some Ospreys do not migrate. They include those living in warmer climates year round such as Australia, Singapore, other parts of Asia, and parts of the southern United States including Florida.

Solly was born on a nest sitting on a barge at Port Lincoln, Australia. She is an Eastern Osprey and they are critically endangered. Look carefully and you can see the satellite transmitter on her back. She has a bright orange band on her left leg and a metal one on the right. Solly is easy to spot and many are taking her photograph as she travels the Eyre Peninsula of Australia moving north from her barge nest. I often report on her movements and from those the researchers are changing their minds about how far Ospreys travel from their natal nest.

One of the most famous Osprey couples has their nest on a 75 foot high World War II Whirley crane in Richmond.

They are Rosie and Richmond and Richmond – well, everyone loves Richmond! Richmond is quite the character. He loves bringing blankets and stuffed toys up to the nest.

One of my most favourite Ospreys is Iris. She is not named after the flower but because she has some very distinctive spots on the iris of her left eye. Iris is the female at the Hellsgate Nest in Montana. For many, many years Iris and her mate, Stanley, nested at the site and raised many chicks. Stanley did not return in 2016. Iris’s new mate, Louis, has proven to be unreliable and the breeding seasons have been unproductive. While most Osprey are thought to live up to twenty-five years, Iris is believed to now be twenty-nine years old.

Iris with her distinctive left eye. Cornell Bird Cam, Hellsgate Osprey scap.

During the 2020 breeding season, Iris had simply ‘had it’. Louis, her mate, actually had another family. Iris laid her egg on the nest but Louis did not bring her food or come to relieve her. She had to leave the egg to eat – and, of course, the Ravens were watching and they came and ate it. Iris was not pleased. Then a squirrel climbed up the platform and was trying to get on the nest. Take the time to watch this video to the end. It is only four minutes long. I seriously would not mess with a female Osprey when they are having a bad day. I want to add that Iris was seen fishing and she sometimes returns to the nest. Everyone is hoping that she will come back for the 2021 season with a new partner.

Iris may help avian researchers understand how long wild Osprey can lay fertile eggs. We know that with Wandering Albatross, Wisdom, who is 69 years old is still raising chicks.

Iris is having a very bad day.

Ospreys raise only a single brood of chicks a year. There will be anywhere from one to four eggs. Both parents will incubate the eggs although many note that the female is there more than the male. The eggs are hard incubated from the time the first one is laid. This means that the last chick might hatch six days later than the first. This often results in siblicide where there are three or more chicks. The smallest is just that much smaller and seen as a threat to food resources. That said, I have seen Osprey parents do dual feedings, such as Loch Arkaig in Scotland, with three chicks growing up to fledge with no dominance issues. First pips are normally around thirty-six days. First flight dates really vary from 50 to sometimes as much as 60 days with 55 being the average. The chicks will use their natal nest as a home base. Parents will teach the juveniles to fish and will supplement them with fish they have caught for several months after fledging.

Ospreys were severely impacted by the use of DDT and their numbers declined rapidly. Many countries are working hard to reintroduce them to the wild. I highly recommend:

You can find Richmond and Rosie at: http://sfbayospreys.org/

If you are interested in following Solly, the Eastern Osprey from Port Lincoln, go to: https://www.facebook.com/portlincolnosprey

You can reach the Kielder Osprey Nests through the following URL: https://www.visitkielder.com/play/discover/kielder-ospreys

If you have a favourite Osprey nest, please let me know. I would love to hear about it.

Update on Solly before I leave. Solly is now 157 days old. She spent yesterday back at Eba Anchorage. Locals say she is staying in a small marshy area near the town.

Thank you so much for joining me today. Hope to see you again soon!
