A nocturnal species, Fraser’s eagle-owl commences activity at dusk, emerging from its daytime roost to hunt. Camouflaged amongst the trees, this species sits motionless on its perch scanning the forest for prey, before swooping down and snatching its victim in its talons. Fraser’s eagle-owl feeds on a variety of animals including insects, frogs, small birds and mammals such as mice, squirrels, and fruit bats (2). Because Fraser’s eagle owl swallows its food whole or in large pieces, it ingests a great deal of indigestible matter such as fur, feathers and bones. Like other owl species, this is transformed within the owl’s digestive system into a compact pellet that is regurgitated a number of hours after eating (4).
Little is known about the reproductive biology of Fraser’s eagle-owl. The few field records indicate that egg-laying occurs throughout the year and that the young probably do not become independent until around a year or more after hatching. Nests are likely to be constructed on the ground or in tree hollows (2).
