Klaara on evening flight out of nest
Tawny owl Kodukakk Strix aluco
By today all owl chicks have hatched.
A brief survey: on March 30 we could see the first egg in the nest. The next eggs Klaara laid on April 2 and 5.
When exactly one month had passed, or on April
We can see that the age difference between the first and last chick to hatch is three days.
