Mom returns to Collins Marsh and a Pip Watch in Australia

The female Osprey with a chick on the Collins Marsh Reservoir nest in Wisconsin was away from the nest for 21 hours. This is most unusual. At this time, no one is clear about what happened to her or where she was. She remained on the nest all Sunday, without leaving once and Sunday night. She returned Sunday morning around 9:40 and began feeding the chick. She has already fed the chick this morning. There remain concerns for the condition/growth of the chick’s feathers, particularly those on the wings.

Update: I have just heard from Stephen Easterly, the DNR Biologist for the area, and he feels that the chick is progressing fine. It is walking, self-feeding and we will all now look towards a successful fledge. Thanks to everyone in Collins Marsh for their concern for this chick and their quick response to viewer’s calls.

Sadly, it is going to be another scorcher in Wisconsin today.

Did you watch the Barlineck Osprey Nest in Poland? That nest is on top of a 35-meter pine tree with an artificial platform. There were four eggs laid, but only two hatched – the first on 25 May and the second on 31 May. There was a huge size difference (of course) between the two. Despite that, I received word from Michael Zygmunt of the Polish Eagle Committee in Poland this morning that both chicks fledged successfully. Their camera is out of operation. They replaced the router but discovered that the cable connecting the camera and box is damaged. They will not repair it while the nest is active. So please don’t forget about this wonderful Osprey nest next year. And so happy that both of those babies are flying.

Everyone loved Aila, Louis’s mate at Loch Arkaig, that did not, sadly, return this year from her migration. Louis has a new mate on a nest that has no camera. Today, a short video clip of the two chicks was put on YouTube when they were ringed. Both chicks are believed to be males, and their ring numbers are Blue LW3 and Blue LW4.

And, as the Osprey season dies down in the Northern Hemisphere with the chicks honing their flying skills and staying off-camera, things are about to pick up in Australia. The pip watch for the White-bellied Sea Eagles, Lady, and Dad, begins today, 27 July, in Australia.

The White-bellied or White-breasted Sea Eagle is the second largest bird of prey in Australia. They have a wingspan of 1.8-2.2 meters or 6-7 feet. There is the same reverse size-sex ratio in these birds as in other raptors meaning that the female is larger than the male. Sea-eagles, or Fish Hawks as they are called in some places, live along the coasts of Australia, Southeast Asia, and India. You can also see them in New Guinea, and there is quite a number around Singapore.

The adults have a white head and belly, underwing coverts, and tail. The upperparts are the most beautiful slate blue-grey. The juveniles change from a white fuzzy bobblehead to a bird with a light brown head and breast with underwing coverts of rust, a ginger red and dark brown mixed with white. Their tails are white with dark tips (only present in the first year). After several annual molts, the juveniles will change to adult plumage.

The breeding season is from June to January. A clutch of two off-white eggs is laid two to three days apart in a huge stick nest.

There is a nest cup in the middle. Both parents will incubate the eggs. As of 23 July, Lady has incubated the eggs for 215 hours, and Dad has incubated the eggs for 131 hours since the first egg was laid. Both parents feed the chicks, but, in general, the male brings in the prey, and the female at this nest feeds. The chicks will fledge at around 75-85 days. If all goes well, they will remain in the nest area for several months, being fed by the adults as they gain their flying skills.

Lady and Dad have their nest in an old Ironbark Tree in the forest of the Sydney Olympic Park. There is restricted access around the nest during the breeding season.

It isn’t just the Sea Eagles, though. Mom and Dad have been busy refurbishing the nest on the Port Lincoln Osprey Barge. In fact, Dad has been cleaning up the coastline, bringing several plastic bags lately to the nest. Hopefully, someone will remove them. Why do Osprey males like to bring non-bird items into the nest? I wonder if Mom likes the softness of the bags compared to the sticks?

Last year’s fledglings from this nest, Solly and DEW, made the news on Sunday in Australia. The picture is of

Solly has a satellite tracker, and it has really helped with our understanding of Osprey.

The lead researcher, Ian Falkenberg, commented: “Solly has so far traveled about 520km from Port Lincoln. We didn’t expect her to travel that distance because ospreys in Australia are non-migratory,” he said. “The second thing that surprised us was the distance flown inland. They live predominantly on fish so why she would spend time out there in those areas we’re not sure, other than taking exploratory trips.”

Solly has spent most of her time around Streaky Bay and Eba Anchorage. A few days ago, she moved to Smoky Bay, where the fishing is supposed to be very good.

The last check on Tiny Little at the Foulshaw Moss Nest revealed no one is on the nest in the late afternoon in Cumbria! Apparently, Tiny Little no only held off its big sibling from getting its fish yesterday but got upset with Blue 464 and pecked at its head rather hard! Now that is a first, too.

Thanks, everyone, for joining me on a partly cloudy morning on the Canadian prairies. See you soon! Take care.

Bird World – late Monday and early Tuesday ramblings

It has been a day for extreme weather. 44 degrees C in the Pacific Northwest and a snow storm on Taiaroa Head, New Zealand, home to the Northern Royal Albatross colony and their chicks. It is 38 degrees C – and ‘boiling’ my friend living at the base of the Purcell Mountains in British Columbia said. It is 24 degrees C in St Petersburg, Florida where Tiny Tot lives and 27 degrees C in Ithaca, NY where the Ks live. It is 27 degrees where I am on the Canadian prairies with the temperature climbing to 36 degrees C in a couple of days. We will fill extra bowls of water and try and find a sprinkler for the birds as well as keeping their feeders topped up.

Our local crow colony displayed some interesting behaviours in the late afternoon. First, two were on sentry duty on the telephone poles nearby. Each was making a different alarm. Then four other crows flew in and over our house. They were quickly joined by another five or six until 19 crows were in our front tree. We did not see the Great Horned Owl that lives over on the golf course coming to check if there are any nests it could raid. So we are still left wondering what was going on.

Crows defend their territory by summoning friends and relatives to help them annoy the intruder enough so it leaves in our neighbourhood. As things settled down, Mr Blue Jay flew out of the trees to come for his 5pm bath and food but, something alerted him and he decided he would wait. I don’t blame him. Those crows were really in a dither! The intruder remains a mystery.

All of this got me to thinking about Electra. Electra, if you do not know, is the mate of Wattsworth at the Cowlitz PUD Osprey Nest in Longview, Washington. Electra hatched two chicks this year. The nest is notorious for not having sufficient food and the chicks dying. This year there was one siblicide and yesterday, a chick with promise -if enough food came in- died of heat stroke. It was the first known Osprey death due to the extreme heat in the region but it is very possible that it will not be the last. Electra was out fishing since Wattsworth seems incapable. Believe me I have a lot I could say about him! But, right now I want to pull my human heart out of the equation and look at Electra’s behaviour in light of Aran’s present to Mrs G today. So, I want to rewind and I needed to go for a walk to think this through.

Electra leaves the nest to go and fish for her and the remaining chick. When she returns, that chick has died due to the extreme heat on the nest. Electra has a fish that was for her and the chick. Wattsworth arrives at the nest. Electra refuses to give Wattsworth any fish. Then Electra stays on the nest, fish in her talon. There is no need to brood a little one. It is dark and is unsafe for her to fly. Some Ospreys are known to fish in the night – certainly Louis at Loch Arkaig would fish 24 hours a day, 7 days a week to feed Aila and the three chicks last year. But Electra is going to hold tight on the nest until dawn breaks. She then leaves the nest taking the fish with her. Electra’s motherly duties are over. It is unclear what the nest actually signifies to Electra now that the chicks are dead. We know that Aran brings Mrs G a fish today as a means of bonding. Iris returns to her nest to renovate. But what, if anything, this place is to Electra right now is not known.

Electra returns to the nest with what I want to call a ‘fish tail’ later. It certainly wasn’t the big hunk of fish she had with her last night. It could be what remains of it. There is no one to feed on the nest. So why is she up there with a fish? She could eat it on a tree branch in the cool shade of the river, right? That would have been the smart thing to do to do in this heat. She is horrifically hot, panting hard to try and cool herself.

I know of two male Ospreys who like to steal the fish from their mates – you possibly know many more! But I am thinking of Louis and Iris and now Wattsworth and Electra. I am also beginning to consider the need to bond after a tragedy. We see that with Aran and Mrs G. The need for Aran to be able to provide for Mrs G and for her to accept the fish from him.

Electra is looking and calling while she is on the nest with the fish. I now believe that she was calling for Wattsworth. I also believe that she was going to give the small fish piece to him. It doesn’t matter what I think of Wattsworth. Electra needs to bond with her mate after the death of her last chick. It is precisely what is happening on the Glaslyn Nest. Aran and Mrs G are bonding, too. This is just another way to look at the behaviour of Electra. The reality is we will never really know. We all wish her well.

The big winner in the fish category today had to be Tiny Tot over on the Achieva Credit Union’s Osprey Nest. My goodness, gracious. Jack came in with a fish for Tiny Tot at 6:41:16 and it was a whopper. I wish we could have seen Tiny’s eyes – they were probably popping out! But never fear. Tiny Tot learned its lesson months ago – you sit there and eat that fish as fast as you can because someone might come along and want to steal it. And you never ever leave anything on your plate!

Tiny Tot must have thought she had won the lottery. Jack has certainly been very good to make sure that Tiny gets fed. I would like to think that he is making up for when Tiny Tot was starving to death but, that would be putting another human spin on things. Obviously, Jack likes Tiny around. She protects the nest and he isn’t in any hurry for her to move on or he would stop bringing fish. It is a sweet deal for both of them. Jack doesn’t have to worry about getting injured fighting off an intruder. He can spend his time down by the water fishing and bringing Tiny Tot a few fish each day. Tiny is getting heaps of real life experience. Personally I am glad that he is feeding Tiny Tot. If she is to be the survivor of the chicks on this nest (the average is only one out of three), then the longer she is fed and the longer she stays on this nest, the better equipped she will be if she ever leaves the nest. Tiny is a bit like Izzi, the Peregrine Falcon juvenile, of Xavier and Diamond. Izzy is still around the scrape box and she should have left for his own territory long ago. But that is another story for another day. There should be no worries about Tiny being able to fish. It is embedded in them. Jack doesn’t have to teach her. That is ingrained into her and every other Osprey and has been for 65 million years. Now she might not be as good a fisher as an osprey more experienced but she knows the moves and just has to find fish. I loved the stories of Bellie in Belle’s Journey, the way she honed her fishing skills. Tiny will do that, too.

Look at those legs and that little bottom. I think that the chicks on Cowlitz really got to me because of what Tiny Tot went through early on. But, as those who watched the Achieva nest, things turned one day. Diane brought in fish and I quit calling Jack a ‘dead beat dad’. They began to be a team and they succeeded in fledging three chicks. Amazing.

When I think of those super male Ospreys that get wall murals or the ones people talk about decades after they have passed, it is always the praise for providing for their family. Yes, people talk about Blue 33 and Idris’s fishing abilities and the whoppers – but it is always tied to them bringing those to their family and how healthy their chicks are and the pride in counting the children and the grandchildren in the family lineage.

So we go back to the survival of the fittest, perhaps. Wattsworth’s DNA is not being passed along but Monty’s, Blue 33s, and Idris’s is. And I hope Tiny Tot’s!

It was raining in the Sydney Olympic Park today. The beautiful canopy of leaves on the old Ironbark tree where the nest of Lady and Dad, the resident White-Bellied Sea Eagles, is located kept Lady from getting soaked. Lady is incubating two eggs. It is awhile until we will be on hatch alert. I will let you know when that happens so you can join the fun.

The rain finally stopped in Ithaca and the Ks were quite happy. K3 is eating again! It is nice to see the sun come out so they can dry off. It is even nicer to see the pair together on the nest safe and sound.

And, last I am showing you an image of the nest at Loch of the Lowes. I will also try and find the short videos that someone took of NC0 fishing in the loch. She is good! In this image the nest is getting a little crowded with the wingersizing of these two big osprey chicks. Safer for NC0 to get out of the way and sit on the perch, for sure! I was fascinated in the camera set up. That is why I am including this image. It is rather amazing. There is also a microphone in the nest so that you can hear the chicks when they are peeping in the egg right before hatch.

Here is NC0 fishing:

A snow storm and high winds have put out the cameras on Taiaroa Head in New Zealand where the Northern Albatross and their chicks are. They will love it. These birds like the cold. The staff of the NZ DOC (Dept of Conservation) have sprinklers to cool off the chicks. That camera should be back on line along with the weighing of the chicks. The chicks are weighed weekly, unless there is an issue and they might be weighed more. Supplemental feedings by the staff are given if the weight of the chick is not where it should be. That could come from parents not returning, being injured and delayed in their return, etc. NZ looks after their wildlife and accepts that humans have impacted it. There are not the complications with intervention like there are in the US.

Sad news coming out of Canada and the Osoyoos Osprey Nest. It appears that two of the three chicks have died to the incredible heat in the area in the same way that the chick on Cowlitz did. The other chick will require lots of fish but it is not looking very well this morning. A former student and close friend of mine now lived on the edge of the water at Osoyoos and really enjoyed seeing the Osprey family fish. They were forced to move because of the smoke from the wildfires that hits the area every summer. Prayers for all the birds. The heat wave is spreading across North America.

Thank you for joining me today. There will be a big nest catch up later today.

Rings and an Egg

The weather at Rutland Water calmed down enough that the two chicks of Maya and Blue 33 (11) could be ringed. Some people call this ‘banding’ but in the UK the common term is ‘ringed or ringing’.

What are Darvic Rings? The Darvic rings are a plastic ring that is fitted to the Osprey’s leg. Normally you can see them from a distance with binoculars or a spotting scope. Different countries use different colours. In the United Kingdom, the bands are blue with white lettering. Scotland places the Darvic ring on the left leg while England and Wales put it on the right. In Spain the Darvic rings are yellow, in Germany they are Black, and in France they are orange. Over time the amount of numbers or letters has changed but there are registries of every bird that is ringed.

The birds are also fitted with a metal ring. It has a unique number and address and is more durable than the plastic ones which can, after several years, break.

Birds are ringed before they are 45 days old. The reason for this is so the specially trained banders do not frighten the birds and cause them to fledge prematurely. Also, the leg will have grown to its adult size. This prevents the ring from getting too tight and injuring the bird. Ringing often takes place when the Osprey chicks are in the 30s – such as 36 days old, etc. At the time of banding the chicks are weighed and measured. Indeed, everything about them is measured!

The two chicks at Rutland Water’s Manton Bay Nest were ringed this morning. The oldest, chick 1, has the number Blue 096. Chick 1 is a male weighing 1540 grams and having a tarsus thickness of 13.6mm. Chick 2 is a female and is Blue 095. She weighs 1650 grams and has a tarsus thickness of 15.6 mm.

Just try getting a good image of the two birds showing both of their bands at the same time! It seems like it has been impossible. Here you can see one of the bands of the chicks – look carefully you will see 095 – chick 2, the female.

Other exciting news is that Lady at the White-Bellied Sea Eagle nest in the Ironbark Tree in the Sydney Olympic Park laid her first egg on the evening of the 19th of June. Hundreds of people cheered watching.

She seemed very uncomfortable and then after the reveal she joined Dad on the branches of the tree.

The White-Bellied Sea Eagle is the second largest raptor in all of Australia. Their wingspan is from 1.8 to 2.2 metres. Females are bigger than the males – reverse sex size diamorphism. She will weight from 2.8-4.2 kg while the male will weight from 2.5 to 3.7 kg. The adults have a white head and belly which you can see in the image above with the most beautiful blue grey wings and beak.

You can see the nest. It is extremely large with an egg cup in the centre. It is made out of twigs which are carefully restored by the eagles every year. Lady and Dad have been working on getting the nest ready for several months now. This nest in the old Ironbark Tree is close to the Parramatta River where the sea eagles fish.

Lady will lay one more egg – what old timers call the ‘insurance’ egg in case something happens to the oldest chick. That will be in 2 or 3 days. She will do all of the incubating at night and Dad will help her during the day. Hopefully, both eggs will be viable and there will be two healthy chicks. Last year both chicks fledged. The oldest, WBSE 25 fledged first and did not ever return to the nest. WBSE 26 fledged, returned to the nest to rest, and then was found on the balcony of a 22nd floor condo after she left the nest for the second time. Right after hatch 26 had its leg broken and it did not heal properly. At the time no one thought she would be able to stand but encouraged by its older sibling, 26 did everything and fledged. Sadly, it was too injured to live in the wild and the veterinary surgeons thought any measures to ‘fix’ 26 would only result in endless pain for the bird. Sadly, 26 was euthanized but not after this gorgeous bird touched thousands of lives.

You can watch the action of the White-Bellied Sea Eagles here:

Ah, quite exciting. Hatch will come in about 40 days.

The White-Bellied Sea Eagle Cam in Sydney, Australia is the only streaming cam following these beautiful birds in the world. They live along the coast of Australia and can even be found in the Singapore harbour.

They are such beautiful birds.
