The Scops Owl is fully nocturnal and mostly insectivorous. It is a bird of scrub and bush territory, and often uses ground nest sites for breeding. It is a small owl of only about 17cm and lays its 4-6 eggs in a tree cavity from April – June. Incubation about 27 days. Young fledge by about 30 days. Its call is a soft croaking, frog-like “prrrup-prrrup”.
Barn owls (Tyto alba) roost and nest in old barns, ruins and neglected buildings as well as in trees and sometimes cliffs. They have a long breeding season starting in early Spring and may rear two broods.
The size of each clutch can vary from as few as three to as many as eleven but is usually between four and seven, depending on the supply of food available. The male will feed the female while she is incubating the eggs, a period of about five weeks.
The young owls are born covered in white down and twelve days later develop a creamy coat which will eventually be shed to develop the characteristic golden upper coat mottled with grey and the white under feathers of the adult. The young owls are ready to fly at eight to ten weeks old.
