When female eagle  Suvi rose for a moment from the nest in the morning a little before half past seven the eagle chick had hatched….

Body

 

White-tailed eagle       Merikotkas      Haliaeëtus albicilla   

 

Thirtyseven days of incubation in the cold spring, sometimes even in a snowdrift.

The chick was hatched from the first egg laid on March 18. From the incubation period we can deduce that the egg that was crushed on April 5 was laid on March 21.

Yesterday we saw holes in the egg shell and sounds from the eaglet were audible. For large birds the hatching from the egg takes more than 24 hours because the chick must get used to breathing oxygen..

The adults don’t help the chick at the hatching. Chicks must prove their vitality by an unassisted hatching.

At the hatching all chicks are aided by a sharp “egg tooth” that helps to produce a crack into the shell in the limited moving space and to hatch. An attentive observer may notice on the upper beak half of a just hatched chick the whitish egg tooth before the tool after some time drops off.
