Physical charateristics
Spectacled Owls are dark brown with a whitish to yellow-ochre belly, a white patch on the front of the neck and a dark brown belt across the breast. White “spectacles” around their yellow eyes give them their name.
A juvenile has the adult markings in reverse – a white head with black mask, and may take several years from hatching to attain full adult plumage.

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.
Reproduction
In Costa Rica, eggs are laid in the dry season, 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.
Feeding habits
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.

Conservation
This species is considered Critically Endangered because it is confined to two sites containing extremely small and fragmented patches of severely threatened forest. Unless there is urgent conservation action, it could become extinct very shortly.
Pulsatrix perspicillata can be found from Southern Mexico through Argentina. It can also be found on Carribean islands such as Trinidad.
