The stygian owl (Asio stygius) is a species of owl of the family Strigidae, and found throughout much of Latin America. Despite the name, the stygian owl was named for its "gloomy and dark" color,[2] and not in reference to the River Styx of Greek mythology.

Description

Stygian owls are medium to relatively large in size, with a length of 14.9 to 18.1 inches. Females are larger than males. Like many other owls, it has striking ear tufts; instead of being on the corners of the face, the tufts are rather close together between the eyes. The upper portion of the plumage is a sooty-brown with individual pale patches; the underside is speckled dark brown on the breast, with the belly bearing dark longitudinal and transverse striping. The wings are relatively long, the tail is short. The eyes are yellowish.

Stygian owls are active at night and into the dawn. At rest it seeks seclusion within the dense foliage of trees. Diet includes small animals, generally rodents, bats, birds, as well as lizards. Reproduction is largely unknown; what is know is that these owls lay no more than two eggs, with incubation by the female only.
