ID Keys: Dark overall, obvious ear tufts, dark beak, dark
upperparts, lighter underparts with dark vertical barring
The
Stygian Owl is a bird of Mexico, Central America, and the Caribbean.
While its range is well south of the United States and it is typically
non-migratory, the species has twice been found in south Texas. The
term Stygian refers to the river Styx, a term that in this case likely
refers to the species' overall dark coloration rather than any association
with "hell". The ear tufts that are obviously visible in the photo to
the right are often only visible when the owl is alert or agitated, as
relaxed Stygian Owls often show little indication of ear tufts.
Habitat
In Mexico, they are often found in open
pine and pine-oak woodlands and forests. They often occur in montane
forests, and are found much less often at lower elevations.
Diet
Stygian Owls will feed on a wide variety of
prey items, including small rodents, bats, birds, reptiles, and large
insects.
Behavior
The species is nocturnal. During
the day, it prefers to roost undisturbed in dense vegetation. At
night, foraging is often done in more open habitats, however.
Nesting
Stygian Owls have been noted for nesting
in stick nests built by other species, but they have also been found to nest
on the ground, and nest in junctions of large tree branches. The
female evidently incubates the eggs by herself, but both the male and female
will help to raise the young.
Song
Males have a strong, desending Huuuuu.
Agitated birds of both sexes have a wok-wok-wok call.
Migration
Stygian Owls are considered permanent
residents throughout their normial range.
