Thursday morning in Bird World

21 April 2022

The snow that was forecast did not materialize in southern Manitoba and Winnipeg. That is wonderful! We needed a break from the last storm to melt the snow and to be outside. The birds needed a break in the weather, too. Sadly, there is another special weather advisory for the southern part of Manitoba starting tomorrow morning through Sunday. Perhaps we will only get the wintery rain. Oh, the poor Wood Ducks. They have just arrived.

IMPORTANT INFORMATION: The Q & A session on Cal Falcons is at noon in Berkeley! When you go to the YouTube site and set the alarm reminder, it will confirm your local time – hence the confusion. Thanks ‘B’ and ‘S’.

You can tell by Big Red’s demeanour that ‘something’ is happening. She does a little wiggle and then you catch her with this focused look as if she can see the eyas advancing in its pecking. Of course, she can hear it cheeping and, apparently, so can the other three. Some believe that this encourages them to hatch faster so they can join their sibling. That would be grand.

Arthur revealed the progress of the hatch when there was a shift change.

Hatching!

The White-tailed eagle nest of Tula and Borek in the Tuchola Forest had three eggs. The eaglets hatched on 8, 12, and 14th of April. There are only two surviving eaglets today. Siblicide is not as widespread in White-tail Eagle populations as it is in Golden Eagles. That said, when the third eaglet hatched the eldest at this nest began immediately to beak it. There was 6 days difference in their age and size. I believe the two surviving are hatches 1 and 2. I will refer to them as Big Bob and Middle Bob to try and keep things straight.

Today, Middle was clever and crawled up leaning half in and half way out of the nest cup so it could get some food. This is a very determined youngster. The eldest had eaten and so the youngest was not tormented. I hope that these two survive just like the two oldest hatches at the Dale Hollow Nest.

The nest is 25 metres above ground on a 140-year-old pine tree. The White-tailed eagles have been using the nest for four years. At another place in the forest, eagles had been nesting since the late 1990s on a 160-year-old pine near to one of the fish lakes. So for 25 years eagles, at some location in Tuchola Forest, WTE have been breeding. There is a year round protection area around the nests extending 200 metres in any direction.

The nest is located in this large, 46 sq kilometres, nature reserve in northern Poland. The two main types of trees are the Pine and the Oak Bartek. It is the oldest oak tree in Poland believed to be 686 years in age.

“Polek i Bartek w jednym lesie stali” by Polek is marked with CC BY-NC-SA 2.0.

The park is full of rabbits, deer, and 80 species of birds. There are also nearby rivers for fish. It is anticipated that there should be plenty of food for the adults and both of the chicks.

There are about 1200-1500 pairs of White-tailed Eagles in Poland. Their conservation status is ‘very scarce breeding bird’. Most of the eagles live in the northern areas of Poland.

Here is a link to this White-tailed Eagle nest in Poland:

Both eaglets were being fed well Thursday morning:

Idris and Telyn were watching the train go past the Dyfi Nest in Wales. Two eggs. We will be watching for the third tomorrow.

Little (or Mini) is still on the nest with Lena and has not fledged yet. Middle (Little) took off this morning about 10:05 for a flight and is perched on some greenery near the nest. He is probably going to watch for when Dad delivers a fish. This morning Lena has also had to chase away an intruder, another Osprey.

It looks like the MN-DNR nest is getting a bit of sun this morning. It will help dry out the nest of Harry and Nancy but will they get some of that snow and rain that is coming?

What is enfluffeling?

Jackie and Shadow’s 2022 eaglet, Spirit, sure loves it when the wind blows hard through the nest. She is working those wings today!

For all us worrying aunties and uncles, the cam operator did Zoom out and there are three eaglets on the West End nest. Relief. When the camera is in the normal position, you might only see two.

This is the view of the Glacier Gardens Nest this morning. Oh, it is beautiful. Liberty and Freedom should be returning soon.

It is a bright sunny day for Chase, Cholyn, and the little one at the Two Harbours nest.

Jasper and Rocket from Samson and Gabby’s NEFlorida Bald Eagle nest have both fledged. They have also returned to the nest. Yahoo. Today they were perched on a branch of the nest tree looking out. I wonder if they might do some tandem flying?

Mum flew in with a hunk of fish at 09:22 at the UFlorida Osprey nest. Look where where that one osplet is positioned for the feed! I believe this to be either Big or Middle. It is not Little Bit.

That chick got a lots of nice big fish bites while the other two were fighting at the back of Mum. It is difficult to tell who is who and the dark shadow is not helping. I first thought it was Little Bit on the rim of the nest but I believe that Little Bit is getting hammered by Big while it is Middle eating. But that is not a 100% certain ID.

The chicks are really, really hungry. Clever of that one to get up there to be fed. It walked away and fell into food coma. Smiling. Ah, is he playing possum? He looked up to see the other two eating. Wonder if he will return for some more fish?

That osplet would certainly like some more fish.

Sadly it looks like Little Bit is lodged between Big and Middle. This is not good especially with less fish coming on the nest and the hot weather dehydrating the little guys.

Little Bit cannot seem to get around the bigger sibling. He will be getting tired and dehydrated.

At 10:00 the Big sibling was laying on top of Little Bit.

I do not believe Little Bit did get any fish. The feeding was over and Mum went to brood the chicks.

I will monitor the UFlorida nest on and off today. What looked good a few days ago has now turned. Let us all hope that another big chunk of fish gets on that nest quickly so Little Bit can have some food.

This is the latest on the hatch for Big Red and Arthur. The image was shot in a change over from Arthur to Big Red. I am really hoping that is blood from a prey item.

Thank you so much for joining me today. Take care everyone. I will be back with what I hope is good news on Little Bit later today along with hatch news from Cornell. See you soon!

White-tailed Eagles in Poland

3 April 2022

One of my favourite White-tailed eagle females is Milda. I have mentioned her before in my blog. Her nest is in Durbe County in Estonia. It has been a rough year for Milda since her long-term mate was missing and presumed dead in late March of 2021. Milda heroically tried to incubate the eggs without food for 8 straight days to the point of starvation. Several males offered hope and then didn’t. As if with a miracle the two chicks hatched and we all celebrated only for them to perish because of one of the males taking the food off the nest and then not covering them. But, that was last year, and there was hope for this one but again, disappointment when the eggs laid were broken by an interloper.

The females on the nests need a good strong partner who is working with them cooperatively!

The White-tail Eagle is so rare in Eastern Europe. Latvia, Estonia, and Poland are doing what they can to encourage breeding sites.

The White tail eagles are Haliaeetus Albicilla. They are the largest raptors in Europe and are located from Greenland to Asia. The Eagle Directory describes the plumage like this, “White-Tailed Eagles are almost entirely brown. They have a yellow-gray head, neck, breast, and lesser wing coverts, and the belly, thighs, and rump are dark brown. The flight feathers are close to black and their wedge-shaped tail, as their name would indicate, is white. The tibia are feathered, though the tarsi are not, and the legs and feet are yellow. The eyes, beak, and cere are yellow.”

As you can seen from the images of the White-tailed Eagles below, the plumage can vary and of course, we have to take into account the lighting and settings on these streaming cams. These eagles grow to be from 74-92 cm long with a wingspan of 193-244 cm. The females are larger than the males as in most raptor species and weight between 3.7 and 6.9 kg. The males come in at 3.1 to 5.4 kilos. Their life expectancy can be up to 36 years. They eat mainly fish but also hunt mammals such as rabbits and birds. I have seen them also be opportunistic and bring some carrion to the nest. Indeed, it was a crane brought to the White-tailed eagle nest last year that killed two wee chicks because that crane brought with it the highly pathogenic Avian Flu, H5N1. While the birds are listed as not being under threat in some areas, they are very rare in Eastern Europe and the UK is trying to reintroduce them. While they may lay 1-3 eggs, it is most typically 2 eggs that will be incubated by both parents (as you see below) and hatch within 34-46 days. Fledging typically takes place between 77-90 days after which the fledglings are depending on the parents for 4-6 weeks while they learn to fly and hunt.

In older White-tailed eagles, the head and neck can be almost white.

The adults in the images are in a nest in the Woziwoda Forest District. It is a special project of the Eagle Conservation Committee, the Woziwoda Forest District and Polish Radio promotion both old forests and the White-tailed Eagles. The nest is highly protected. There can be no activity within a radius of 200 m. Setting up the camera were problematic and the workers who installed it had to do this cautiously when the eagles were away.

The nest you are looking at is on a 140 year old pine tree at a height of 25 metres. This nest has been occupied for four years. It is known that there was one fledge in 2021.

For transparency, I do not know any of the history of this nest so I do not know whether to give you caution or not. I am attempting to find out. The setting is simply beautiful and if some of you have been watching this nest in the past, please let me know. The chat is in Polish and I understand eggs are being incubated but it is not clear how many or when they were laid by the information provided.

Here is the link:

Just an update on 2 other nests: The adults at Dale Hollow have brought in a teaser 2 bite fish and a small sucker early in the morning. Big ate both of them. No other food has been provided to the eaglets up to 18:30 this evening. I sure wish they would bring a whopper on the nest tonight for both. That said, Little Middle ate well yesterday and is OK. Sadly, Little Middle continues to pull that monofilament line. Thank you to ‘CA’ from Belgium who sent me this 15 second video clip. I could not see him dragging the nesting material, my mistake.

Annie and the new male continue to bond in the scrape box. I have caught him incubating a few times today. I sure hope he is a good guy to our Annie! I don’t think any male will ever fill Grinnell’s shoes – he was a huge character in every aspect of a raptor’s life but any bird who will care for Annie, Grinnell’s eggs and now on of his own is gold in my books!

Karl II has spent his 4th night in the Ukraine not far from Kyiv. Anne7 posted this image of where he was hunting for food this afternoon. I am so grateful for the Looduskalender Forum and their English pages and to the tirelessness of Anne7 to inform all of us of Karl’s whereabouts. I wish him to replenish his energy and get to Estonia! Fast.

You may find yourselves spending too much time looking at the Dale Hollow nest hoping for a miracle. I had to begin to pull back today. It is mentally exhausting. We cannot make the adults bring in more food and legions of you have contacted enough people to get help. ‘L’ has had a promising conversation with Al Cerere who asked the important questions. If help can come, he is the guy to make it happen. We simply have to wait and hope. My heart breaks for both of these eaglets but, of course, most especially Little Middle.

Our weather is set to soar to a high of 8 degrees Celsius. We will all be outside in our summer clothes! Well, not quite but it will feel like that. It was a damp day, cold to the bones British type weather today. Birds are arriving and I really hope to get out to see some of them in the morning tomorrow. My post will likely arrive late in the afternoon.

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