Habits: The Crested Owl is a nocturnal bird, roosting during the day in dense vegetation, especially in thickets along rivers. Paired owls often roost together. If disturbed at roost, the owl will become very slim and erect the ear-tufts high. At dusk, singing commences from perches in the middle canopy of the forest, and may continue throughout the night.
Voice: A somewhat frog-like croak that begins with a stuttering rattle, then accelerates to a deep, purring, guttural and rough croak - k-k-kkk-krrrrrrao. At a distance, the lower first part of the call may be inaudible. The song is uttered at intervals of several seconds.
Hunting & Food: Little information available. Feeds mainly on insects, but likely also small vertebrates.
Breeding: The breeding biology of the Crested Owl is little known. Normally breeds in the dry or early wet season. Nests in natural holes in mature trees.
Habitat: Lowland rainforest with undergrowth, mainly in primary forest but also second growth. Ranges from sea-level up to about 1200m in Guatemala and up to 1950m in the cloud forest of Honduras. This owl prefers to be near water.
Distribution: Locally from south Mexico through Central America to Venezuela, Surinam, the Guianas, Amazonian Colombia, Ecuador, Peru, Brazil and Bolivia.
