White-tailed Eagles in Hungary

[Solo]

... 13:40 I'm worried. The eagle has not changed his position. http://up.picr.de/31886546fj.jpg

don't worry - the zoologist wrote (HU chat), it is very important behavior - save energy (12:19:15 it was change)

Btw. I like your very nice country - my cousin living in Labin - Croatia

OK .... thanks, Solo. I'm a bit calmer

OK .... thanks, Solo. I'm a bit calmer

he also wrote: They need to eat a lot - to make up for lost heat. If fishing is freezing, this can be a problem.

I hope, this one is O.K.

Maybe the question is stupid! Can eggs break through the cold? The eggshell is not so elastic anymore.
It is such a pity

sova,
I know about eagles not much - on HU chat wrote that one zoologist.
The body temperature they have 40°C - I think eggs can break only when they are not covered in bad/cold wheater.

Good Morning Sova and Solo

By the WTE- If it is too cold for a very long time, the brood can be lost.

Oh, I found it in my book: Quote:
In severe and prolonged frost, the clutches can freeze.

There will be enough time for another clutch!

BTW:The egg can break in the cold. It happened on an owl nest. You know the owl in the plant pot?

[sova]

Good Morning
Thank you Liz. That's exactly what I thought. Yes, I * know * the owl, the story.
Hope the eagles do not need a second clutch.

Whether the third egg survives?
Solo, how cold is it? do you know that ?

Sova,
I observed all previous days this nest, I have much photos (changes and eggs rollings), but I saw nothing unusual on that 2 eggs (probably it was only dirt, not hole)

- from FB page DINPI: minim. -20°C , I know not exactly where the nest is (this national park is very large), they wrote only: inundation forest area
(the chicks hatching time is the second week in March)

[sova]

Thank you dear solo.
I also just saw the change of guard and the two eggs are looking good. We hope....
The temperatures make me a little worried.

[Solo]

Sova,
