Lesser Spotted Eagles in Poland - 2016/17

[Jujani]

Everything ok, Marfo

Your picture is very nice. Often one can not see the eagle so clearly, because the nest has a similar color.

[Marfo]

Yes, it is remarkable that both eagles and tree have the same colours, dark brown and white.
The picture however looked much better on my screen than on the forum. But that's the result of reducing to 800px.

Thank you, Jujani

I have neglected this camera a bit this year. The chick has become such a pretty eagle.

Sometimes I think the single children (only one egg in the nest) are girls. If 2 eggs are there and the younger one has been killed, the survivor is a boy. But this is only my theory, by no means science. I do not know any statistics. Probably stupid of me.

Just examples from cam nests: Kalev(2012) is a boy from the single egg. Spot(the survivor from 2009) is a girl.

The second LSE chicks are killed even when there is plenty of food. They survive only in two cases: a)if the first egg is not hatched(Tormi, 2011) and b)if the chick is taken away and then returned(like the ones on my avatar).

This is not true!

Just the incidence of such nests is very low. Not every second chick is killed but only very few of them have that goodluck to survive.
The aggression in such nests is lower than usual for LSE nests and it is difficult for the scientists to find generalized answer why.

I have never seen such nests. Every year when we watched LSE cams with two chicks hatched the result was the same: sooner or later the second chick was killed.

Well, I believe that there are much more nests than only those with cams installed. So it s not relevant to claim anything based on those very few what we can see.

Fratricide in Lesser Spotted Eagles is not obligate
as these numbers show:

In Poland, from almost 300 nests, only in 9 did 2 eagles fledged
In Hungary, 2 eagles left the nest in 2 out of 52 nests.
In Belarus one pair out of 48 raised two chicks.
In Estonia Ülo Väli studied 118 broods, only one of them was a brood 2 fledglings. But he published that 2 young eaglets fledge in 1,8 % of broods.

These are only numbers from some studies.

Just some pictures I made a few days ago.
The parent (mum or dad?) sat very close to the cam so I couldn't resist. I didn't have the opportunity to post them earlier.

very nice pictures! Mainly the second one with the eaglet peeking out from the nest

It s Mom. She comes to check a thing that worried her so much during hours following people s visit in the nest (banding and installing camera).

How smart she is! And suspicious.
Do you remember those first 2 (or home many) nights after installing the cam the she left the chick alone for a whole night? I felt very bad to see the little one alone because we all know that this Mom ALWAYS comes for the night to preen and to be with her kid. That strange thing partly caused that she was derailed her from her typical behavior.

[Lubaska]

Very good afternoon

In one hour Dad has brought 3 voles and Mom has brought one big frog.
Eaglet is eating and resting and eating and I would say it must be full... but it is not

[Lubaska]

Now it seems to be saturated totally. Nice big crop can be seen

[Marfo]

Really? Did I miss something last Friday?

[Lubaska]

Food deliveries continue

The little one is full

It cant eat anymore. Nice fat vole is left on the side. What a day

[Lubaska]

No, you did not. Banding and installing happened weeks ago. But she is still curious about that unknown thing as we can see on your pic.

[Marfo]

Ok, I understand.
I have some pictures where she looks right into the camera but only for a second or two. She went to the branch because the chick 'pushed' her away, he wanted to stand where she stood

[Biker]

i also watched at friday afternoon. the weather changed from sunny at noon

to rainy in the afternoon hours. Mom arrived and the chick wanted to be protected by mom

more or less successful.

then mum climbed to the branch in the foreground (where Marfo took pictures round half an hour later).

Biker
I also took pictures half an hour earlier, I have almost the same pictures as you. I made them on the seconds you missed



And a double portrait even earlier. Hope nobody minds going back in time...

[Mamicja]

Food delivery. Dad sat on the branch behind the nest first, then brought a frog to the nest. It was eaten immediately

Great video! Pity that not all 20 minutes of fighting/eating

[Lubaska]

Have you seen Dad in the nest today?

Edit:
I have seen him at 18:14 when he brought a frog
18:21 Mom with another frog
