Choco Screech Owl

The Choco Screech-Owl (Megascops centralis) is a small, cryptically patterned owl in the family Strigidae, found in the humid lowland and foothill forests of the Chocó region of northwestern Colombia and extending into adjacent areas of Central America. Screech-owls of the genus Megascops are characterised by their small to medium size, prominent ear tufts, complex camouflage plumage imitating tree bark, and vocalisations consisting of mellow trilling or whinnying calls quite different from the piercing screech suggested by their common name. The Choco Screech-Owl inhabits the forest interior and edge from sea level to around 1,500 metres elevation, where it hunts nocturnally for large insects, small lizards, frogs, and occasionally small birds. During the day it roosts upright against a tree trunk or in dense foliage, where its mottled grey, brown, and black plumage renders it nearly invisible. Nesting occurs in natural tree cavities. The IUCN classifies this species as Least Concern, with a sufficient range across the Colombian Chocó and Central America. However, the ongoing loss of lowland tropical forest in this region — one of the wettest on Earth — remains a background threat to this and the many other Chocó endemics that depend on intact forest.
