- Megascops cooperi
Otus cooperi
Includes Oaxaca Screech-Owl
Identification
Medium-large owl upto 23cm or 9 inches. It brown with dark streaks on the chest and longish ear tufts.
Distribution
The Pacific coast of south-central Mexico and Central America, to Central Costa Rica.
Taxonomy
Three subspecies are recognized[1]: lambi, chiapensis, and cooperi. Some authorities[2] include chiapensis within cooperi but split the remaining two taxa into separate species: Pacific Screech-Owl M. cooperi and Oaxaca Screech-owl M. lambi. The subspecies lambi has in the past been included in Eastern Screech-Owl but differs among other things in having bristled toes (not feathered).
This and almost all Screech Owls in the Americas have previously been considered to belong in the same genus (Otus) as the European and Asian Scops-Owls, but a reassignment to Megascops have been accepted by among other authorities, the American Ornithologists' Union.
Habitat
It is found in wooded areas as well as semi open sites such as forest edges and trees along waterways.
Behaviour
They are nocturnal but also sometimes seen at twilight, preying mostly on large insects (such as moths, beetles, scorpiones) along with the occasional small rodent.
Voice of the Oaxaca S.-O. form differs from the voice of birds from the rest of this taxon[2].
