4. He carefully lowers his body. (20:00:06)
5. He comes up a little to shuffle the eggs in a good position between his legs, under his belly. (20:00:07)
6. He has now neatly covered all 4 eggs. (20:00:10)
I'm quite sure Kati can do this the same way.
Then why didn't she do it?
I think it depends on how long the egg has remained uncovered. If it has been lying in the cold for hours, it may be lost.
Then perhaps the intention was to reduce the brood size.
If the egg has been "cooled" for shorter times, it may also have been the intention to delay its hatching/development.
That would only make sense if it concerns the first laid egg. (Or maybe the two first laid eggs.) Does Kati know
which egg(s) she didn't cover?
A few years ago I might have laughed with this idea, but the knowledge of birds keeps surprising me ...
Thanks, Liz.
It will be interesting to read the opinion of this BS expert.
This is the (edited Google Translate) text of what is said on Looduskalender:
"Already in the evening was noticed that the female, Kati, left one egg uncovered, and in the morning the same happened again...
The question is: why?
This is certainly not negligence, but the reason is unclear. Does the stork feel that it will be difficult to raise four offspring?"
Good Morning

I hope it is understandable what I mean. I am too tired to search for other words.
