Breeding and reproduction
Owl eggs typically have a white colour and an almost spherical shape, and range in number from a few to a dozen, depending on species and the particular season; for most, three or four is the more common number. In at least one species, female owls do not mate with the same male for a life time. It is common for female burrowing owls to travel and find other mates, while the male stays in its territory and mates with other females.[12]
