The most familiar species is the bam owl (Tyto alba). The bam owl is one of the most widely distributed species of bird, occurring on aU continents but Antarctica, and with about 30 races described, many of which are endemic to particular oceanic islands. The bam owl is the only representative of this family in the Americas, occurring uncommonly through most of the United States and in much of Central and Sonth America. The bam owl roosts in cavities in trees and in bams and abandoned buildings, and it hunts at dusk and at night over marshes, prairies, fields, and farmyards.
