If startled or threatened, it disappears into the hollow. Possessing a fierce disposition when nesting and protecting young, the screech owl launches diving attacks upon the intruder. If out and visible by day, this owl can be a victim of mobbing by smaller birds. Night vision, excellent hearing and silent flight help this bird of prey hunt. This successful species adapts to many environments as long as there are tree hollows for nesting.
Limited migration exists.
Reproduction Owls do not build nests. Late May and June are the brood departure dates. Diet Mostly mice and insects, occasionally other small mammals and birds. Owl's digestive powers are more limited than diurnal birds of prey, therefore, owl castings consist of more bones as well as hairs and feathers. Predators Man, diurnal hawks, Great Horned Owl.
