The white-browed hawk owl (Ninox superciliaris) is a species of owl found on the island of Madagascar.

Description

The white-browed hawk owl is medium-sized, with a body length of 9.8 to 12 inches, a wingspan of 28 inches, and a weight of up to 8.1 ounces. The top is brown and only with some small white spots on the apex and the wing coverts. A broad white stripe is noticeable. The underside is white with brown horizontal streaks. Beak, legs and feet have a yellowish color. The birds show no gender dimorphism.

Due to genetic studies this owl has been placed by some authors in the genus Athene. Further investigations into the final clarification of the genus affiliation are necessary.

Range and habitat

This owl's range encompasses a very wide coastal strip around the entire island of Madagascar, and inland to an elevation up to 2,600 feet; the central highlands of the island is the only area where it is not found. It inhabits evergreen rainforests, wooded savannahs and rocky gorges.[2]

Habits

Only incomplete information is available on this owl's habits. They hunt exclusively at night, feeding primarily on insects, and occasionally on amphibians and reptiles, as well as on small birds and small mammals, such as mice. The breeding season falls in the months October to December. The nests are laid out in tree hollows and are filled with three to five eggs.

Threats

The white-browed hawk owl is widespread on Madagascar and not believed to be threatened. The World Nature Conservation Organization (IUCN) classifies the species "least concern". However, they have also cited the fact that the overall population is declining, with the blame centered on a continued destruction of habitat, such as logging.
