Burrowing Owl has been declining for many years, owing to prairie dog and ground squirrel control programs, also habitat loss, accidental mortality (many are killed by cars). Now considered endangered or threatened in some areas
Habitat, open grassland, prairies, farmland, airfields. Favors areas of flat open ground with very short grass or bare soil. Prairie-dog towns once furnished much ideal habitat in west, but these are now scarce, and the owls are found on airports, golf courses, vacant lots, industrial parks, other open areas.
Hunts mostly at dusk and at night, but does much hunting by day during breeding season. Hunts by a variety of methods, including swooping down from a perch, hovering over fields, or running along ground, then clutching prey in its talons. May catch flying insects in the air.
Diet, mostly insects and small mammals. Diet varies with season and location. In summer in many areas, eats mostly large insects, including grasshoppers, beetles, crickets, moths, caterpillars; also scorpions, centipedes, other arthropods. For much of year, may feed mostly on small mammals (such as voles, mice, ground squirrels), some small birds. May eat many frogs, toads, lizards, and snakes, perhaps especially in Florida
