Common Barn owl (Tyto alba)

The common barn owl, or just 'barn owl', is one of the most widespread birds of prey, living everywhere except desert and snowy regions, Asia north of the Himalayas, most of Indonesia, and some Pacific islands. They have a distinctive heart-shaped face and their underparts vary from white to brown, sometimes speckled with dark spots. 

They are monogamous, which means they mate for life, unless one individual dies. Then, a new pair can be formed. They nest in hollow trees and fissures in cliff faces with an egg average around four speckled white eggs.
