Carnivorous, feeding principally on small rodents and shrews.
Approximately 8 years in the wild and up to 18 years in captivity.
The female can lay 4 to 13 eggs twice a year (in the spring and summer) but usually only once in temperate zones. Incubation lasts 30 32 days. Meanwhile, the male hunts for food for the female. Barn owls nest in holes in trees, barns, rock walls, sandy cliffs, etc. At night, both parents are hunting to feed their young. The chicks leave the nest when they are about 2 months old.
The main predators of eggs and young are opossum, raccoon and other birds of prey. The barn owl can also be preyed upon by stoat, cat and fox.
