Tyto alba

Barn Owl
copyright David Pearson
Length: 16 in. (41 cm)
Active only at night, this ghostly species is most likely to be seen during the daylight hours at its roosting sites in old buildings, under palm leaf skirts, caves, or mines in open forests, grasslands, and near agricultural fields. This species also occurs around the world in a wide variety of habitats. It nests in rafters of old barns, cliff edges, mines and nest boxes when available. The number of young is apparently determined by prey abundance during the preceding winter. Its prey are mostly mice, but also reptiles, frogs and insects, all of which are located primarily by hearing at night. The four-digit banding code is BNOW.
