Tropical Screech Owl
Megascops choliba
The tropical screech owl is polymorphic, with much variation in color. It is overall gray-brown or (less commonly) brown or rufous, but always with a relatively distinctive blackish edge to the face and yellow irides. Its undersides are pale with a black "herringbone" pattern. The subspecies differ in the intensity of the colors and the amount of black markings on the upper- and underparts. Adults are 21 to 23 cm (8.3 to 9.1 in) long and weigh 97 to 160 g (3.4 to 5.6 oz). Voice: The tropical screech owl's primary song is "short, purring trill, followed by two accentuated clear notes". The female's song is similar to the male's but higher pitched. A secondary, courtship, song is "a bubbling bububúbubu". They also produce "a variety of cackles and longer hooting notes".
