Mottled Owl - Ciccaba (Strix) virgata

[画像:Mottled Owl Range Map] The Mottled Owl can be found from Northern Mexico well down into Brazil and Argentina in South America. Its habitat is very extensive and diverse. It ranges from dry thorn forests to humid evergreen jungles. It inhabits elevations between sea level and 7500 feet and is often quite abundant within it's range.
The Mottled Owl is midsize, 13 - 15 inches in length (about the size of a Sharp-shinned Hawk), and strictly nocturnal. It has a varied diet consisting of large insects and beetles, small mammals and birds, snakes, lizards, salamanders and frogs. It may be attracted to artificial lights and is considered an opportunistic feeder. It mostly hunts from a perch, often along a forest edge.
Recent changes to taxonomic classification for both Black-and-White and Mottled Owls put these two in a separate classification in the Ciccaba genius separating them from the Strix genius where similiar owls like the Spotted, Barred, and Fulvous Owls are still classified. These are all larger than the Mottled Owl (if you happen to see them sitting together). The Barred and Fulvous owls have distinguishing horizontal bars on their throats and the Spotted Owl has horizontal bars on its throat and chest. The Mottled Owl has vertical chest and throat streaks and its white backside markings are much less extensive than these others. All of these owls have brown eyes (iris). They also all have distinctive calls.
The Mottled Owl usually lays 1 to 2 eggs between February and May. It generally nests in a hole in a tree or in the top of a broken off palm and sometimes even in vacant nests of other birds. It is resident (other than juvenile dispersals) and not believed to make any migratory movements.
