Monotypic species
Genus
The genus Megascops comprises 22 living species are known at present, but new ones are frequently recognized and unknown ones are still being discovered on a regular basis, especially in the Andes. For most of the 20th century, this genus was merged with the Old World scops-owls in Otus, but nowadays it is again considered separate based on a range of behavioral, biogeographical, morphological and DNA sequence data. Screech-owls are restricted to the Americas. Some species formerly placed with them are nowadays considered more distinct.
As usual for owls, female screech-owls are usually larger and fatter than the males of their species, with owls of both sexes being compact in size, shape, and height. The Eastern Screech-owl Megascops asio is one of the smallest species of owls in North America. All of the birds in this genus are small and agile. Screech-owls are generally colored in various brownish hues with usually a whitish, patterned underside, which helps to camouflage them against the bark of trees. Some are polymorphic, occurring in a grayish- and a reddish-brown morph.
Occurs in two morphs, brown and rufous. It iis large and on first sight uniformly colored. Facial disc buffy-brown with vague rings and an unclear rim. Pale eyebrows. Upperparts tawny-olive with light grey-brown or sandy rufous. Underparts buffy-white with fine bars white-brownish and some dark brown streaks. Iris brown. Wings edges seem to be whitith spotted.

South America : Venezuela to Bolivia
Dense, humid cloud forest and scrub on the Andes slopes at 1200m to 2250m elevation
No data.
Nocturnal hunter, probably mostly insects. Forages in midstorey and canopy.
This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
