Life CycleBreeding occurs between March and July. The Northern Saw-whet Owl often builds a nest in an old woodpecker hole. Females lay 5 or 6 eggs. While the female is incubating the eggs, the male brings her food and protects the nest. Eggs hatch after about 27 days, but the chick's eyes don't open for another week. Chicks first fly when they are about one month old. After 8 weeks, the chicks leave the nest for good. BehaviorThe Northern Saw-whet Owl hunts at night. Its excellent hearing allows the owl to detect prey using only their ears. To hunt, the owl drops out of a perch and grabs prey with its talons. |
