Genus
Members of the genus Strix are the wood owls. They are medium to large owls, having a large, rounded head and no ear-tufts. The comparatively large eyes range from yellow through to dark brown. Colouring is generally designed fro camouflage in woodland, and a number of the member of this genus have colour phases. There are 20 species scattered practically throughout the globe with the exception of Australasia, the South Pacific and Madagascar, where the genus Ninox takes its place. There being no clear generic differences between Strix and Ciccaba genera, and DNA evidence suggesting very close relationships, many authorities now merge the latter into the former.
The upperparts are mostly dark brown to blackish; the underparts and hind neck are white with thin, dark bars. The face and crown are mostly black with speckled white eyebrows and the eyes are dark. In contrast to the simply-colored plumage, the legs and bill are bright orange. Black-and -white Owl resembles the Black-banded Owl (Ciccaba huhula) but the former is largely white below with thin, dark bars; the latter is black above and below marked with narrow, white barring. It has been suggested that the two birds represent color morphs of the same species

Latin America : Central Mexico to Venezuela and Peru.It ranges from central Mexico through Central America to Western Ecuador and, northwestern Peru.
It inhabits a variety of moist tropical woodlands and forests including mangroves, rainforest, park land, and well-vegetated residential areas from sea level to approx. 2400m elevation.
Females lay 1-2 eggs in an abandoned bird or mammal nest, a tree crotch, bromeliad clump, or a tree cavity
Prey includes a large variety of insects and small mammals such as bats and mice. Certain birds have become habituated to feeding at street lights and are easily observed.

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 is very large, and hence does not 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.
