Information

Description: The facial disc is dark brown, bordered by long white eyebrows, white lores and white malar (cheek) streaks. Eyes are bright orange-yellow. The cere and bill are yellowish-horn with a greenish tint towards the tip. The throat is white, forming a semi-collar, while the chin is black. The rest of the head and neck are uniform blackish-brown.
Upperparts are uniform dark brown, merging into a more blackish colouration in the hindneck. Remiges and rectrices are barred with paler grey-brown. The chest has a broad dark brown band at the top, while the breast and belly are uniform pale yellow to yellowish-buff.
Tarsi and toes are almost fully feathered creamy-buff. The unfeathered parts of the toes are whitish or pale grey, and the claws are dark.
Juveniles are feathered mainly white, with a contrasting blackish heart-shaped face and brown on the wings and tail.

Habits: An unsociable bird. Generally nocturnal, with activity normally beginning after dusk and continuing to dawn. Roosts singly by day in trees with dense foliage. Most vocal on calm, moonlit nights.

Size: Length 43-52cm. Wing length 305-360mm. Tail length 164-215mm. Weight 453-906g. Females are larger and heavier than males.

Voice: A series of knocking or tapping sounds with a popping effect "PUP-pup-pup-pup-po", each successive note being lower and weaker, and the rhythm quicker as the series progresses.
The Female also has a hawk-like scream "ker-WHEEER", which has been likened to a steam whistle.

Hunting & Food: Spectacled Owls eat small mammals including mice and the occasional possum or skunk, insects, spiders, many Caterpillars, bats, birds up to the size of Jays, crabs and frogs.
They use a branch to perch on and scan the surrounding area. When prey is located, they drop with a swift pounce. Insects are snatched from foliage.

Breeding: In Costa Rica, eggs are laid in the dry season (mid-November to April), or at the start of the wet season. Spectacled Owls nest in tree hollows and lay 1-2 eggs, which are incubated by the female for about 5 weeks. Chicks leave the nest for surrounding branches at about 5-6 weeks, well before they can fly, but depend on their parents for up to a year once fledged. Often, only one chick will survive.

Habitat: Occurs more frequently in dense tropical rainforest with mature, large trees, including forest edges. Also found in dry forest, treed savannah habitat, plantations and open areas with scattered trees.

Distribution: From southern Mexico, through Central America to most of northern South America. Absent from the slopes of the Andes.
