Choco Screech Owl

The Chocó screech owl is 20.5 to 27 cm (8.1 to 10.6 in) long; two specimens weighed 106.7 and 121.5 g (3.76 and 4.29 oz). It has gray and rufous color morphs and many individuals' plumages are intermediate between the extremes. The gray morph has a grayish white facial disc with blackish bars and a faint black edge, indistinct whitish brows above yellow to red-orange eyes, and short but distinct "ear" tufts. The upperparts are brownish gray mottled with black and buff. The folded wing shows irregular white spots along the margin. Voice: The Chocó screech owl appears to have only one song, in contrast to most other screech owls that have primary (territorial) and secondary (courtship) songs. It is described as "short...trill with a rapid pace" that starts on an even pitch and then drops. The volume varies throughout.
