8:55 - 8:58 both eaglets called, Robis on the branch and Vilnis nearby in the forest.

8:59 - 9:33 Robis called many times.
(again her calls were easy to find because she was so near. Vilnins' calls i didn't look for.)

9:38 Robis flew away.

It was so windy today;

When I looked at the forest, it seems like the top trees have some yellow. Is it logic? or it's too early.

the prey yesterday evening was certainly a (mostly) whitish bird with pale yellow feet.
Image

i can't say whether they were certainly webbed or not... in the clearest pictures they look not webbed.Image

the sea weeds turned into spruce twigs. anyway they came with the bird.
the weeds could be hornwort (coontail is another name; karvalehti in Finnish) Ceratophyllum demersum.

here's a picture of this plant:

this plant looks rigid enough to survive on the dry nest looking fresh for a day.

i made a video of Vilnis eating the bird. he was making the 'cobra' gesture many times. i think it is some sort of threatening gesture.
this is normal view.


i also made a slow-motion close-up of him starting with the bird.

14:57 the fish was gone. an eaglet flew towards the nest tree from the left. i think he landed on the tip of the nest tree. it was impossible to see the extra shaking of the tree because the wind was shaking the tree so much.
Robis screamed and looked up so i am sure that Vilnis was up there.
14:58:37 Robis jumped a little and looked suddenly to the right. then she slowly relaxed. i'm sure that Vilnis flew away then.

......

Yes, Vilnis must have been in the treetop.
I saw that scene live and it made me laugh. Robis also defended the nest against Vilnis, as he did in the early morning against her. What I laughed at was the "sentence" that Robis Vilnis gave along his way out at 15:58:39-47, as if she said, "Yes, fly away, you, go out of the tree, this time I'm at the nest" and she ended with a self-satisfied "hm" and threw her head back slightly. :rotf:
It's so cute to watch, sometimes they act just like human children. :laugh:

ED: Was it a Coot then? :puzzled:
Abigyl,
this is a coot (Fulica atra):
http://starnberg.lbv.de/fileadmin/_proc ... 76dde4.png

In German it's called a "Blesshuhn" or "Blässhuhn", but also "Wasserhuhn" (water chicken) :D

If i remember right, we saw them very often on the Sauces nest and also on Big Bear's (in the winter time, before the fish came).

Thanks, ame,
for the detective work regarding the transformed greenery into "spruce twigs" :thumbs:
Now that you found it out, it's understandable how it came to the nest. :D
Great work :2thumbsup:

a coot?? :puzzled:
the prey yesterday was certainly not a coot. it is definitely out of the question.
the adult coots are black and also the young are dark.

https://en.wikipedia.org/wiki/Eurasian_coot

also the feet of coots are special.

i have no idea what the bird yesterday was. maybe it was a chicken. :rolleyes:
any ideas? :help:

Hello. I follow this nest and chat for some time. I would like to say something about the ‘cobra-posture’.
An eagle can’t move his eyes far down. So when he wants to look at the fish between his legs, he has to turn his head to his chest and downwards to be able to focus the fish into vision.
It’s something I’ve seen often when the forrest-owl feeds her children. To see the little one between her legs, she does exactly the same.

Thanks! as I wrote the coot was a favorite during 2015, since we had other prey. I know How it looked.

hello Lucia65 and welcome!
:gathering:

what you wrote is a very good point indeed! that might explain the 'cobra'-move, at least partially. :nod:
on the other hand, adults don't do this 'cobra'-gesture when eating. there is something specific about this move which is characteristic to young eagles. they didn't do the move before they fledged, not even quite soon after they did fledge. it started a fortnight or so after fledging.

i have read somewhere that the point of sharpest vision in the eyes of eagles is below the horizontal level. it suites well with flying above ground/water and seeing sharp something that is below when the head is in level with the horizon. that is why the eaglets often twist their heads upside down to look at the sibling who is standing on the nest on the same level as they are.

it's getting dark. :offtobed:

Ame, sorry for all the work and photos. I feel guilty for discovering the :chick: :rotf:

I don't like the baby's way mantling and eating, with this special gestures of the neck.

Each time I see him doing it - I get the feeling that it's because his neck suffered and had some damage.

I didn't see any other eaglet doing it, wte or bald.

I really hope he is OK, he is a fighter!!!

It was cloudy in the evening so we won't be able to see the sky :slap:

I'm learning much about birds here but each season they bring new kinds. With Durbertina there was also a water bird, White-grey with long thin legs, we didn't see such a bird this year.

Abigyl, excuse me, if i didn't understand what you were asking for and not yet understand what you are talking about.

So, if you meant the prey from yesterday, why did you ask "Was it a Coot then?", when you know how they look?

They are black, the prey from yesterday was white or whitish.

no, Abigyl i think not. because all in all he seems ok and have a look here:
https://youtu.be/t8y9WqtW0Kk
the eagle on the prey did it also, at the 17th sec in the clip, just in that moment when he supposed the other went towards him from the right (who took a different direction :mrgreen: )
therefore it means: my prey! stay away!

August 13

good morning!

one eaglet is on the top branch and calls every now and then. the other is in the forest nearby and calls every now and then. besides that i think i hear a honey buzzard whistling... it sounds there's more than one of them.

i think we can forget the coot now since this year there have been none.

good morning Bawet!
thank you for you observations! :thumbs:
how do you find those (almost) non-visual eagles? i search for sounds with the Solveigh AVI trimmer by looking at the 'sound track' (the intensity curve) under the picture window.
here's a picture with an eaglet approaching (top left corner) and creaming starting (red ellipse on lower line)
