The Barn Owl’s eggs

It is there, on a mattress of more or less thick ball forms, sometimes also in the straw, that the female deposits between mid-April and the beginning of June, around 4 to 7 white eggs, laid 2 or 3 days apart. Medium size of the egg: 31 x 40 mm (1.20-1.60 inches); weight 20 g. the barn owl can have up to 16 eggs during the fertile years, on the contrary, not laying even one egg during the lean years.

Likewise, the second spawning which is not regular can be observed from July to October. Supplied by the male, the female alone provides the 32 to 34 days of incubation which begins as soon as the first egg is laid. Males and females participate in the feeding of the newly born birds. The young birds are feathered at the age of 2 months and be able to fly between 65 and 86 days.


If the young are content with a dispersal of 50 to 60 km, climatic conditions and especially the abundance of rodents can cause much larger movements; famine sometimes forces the adults themselves to abandon their local lands. The cold and the snow can cause heavy losses; many die of starvation, especially in January and February. Large variations in the populations and fecundity of these birds follow.
