Already in early morning light, at 05.19, Klaara left the nest for a moment and we could see that there were five eggs in the nest hollow

Tawny owl      Kodukakk        Strix aluco

Accordingly the dates of the egg-layings have been: March 16th, 19th, 22nd, 24th and 28th.

The tawny owls are cavity nesters and their eggs are white. The eggs of birds with open nests need protective colouring.

Ornithologists have measured tawny owl eggs: the average dimensions of the round-looking eggs are about 47 x 40 mm.
