Synonyms: Otus madagascariensis (heterotypic)

Wikipedia Abstract

The Madagascan owl (Asio madagascariensis), also known as the Madagascan long-eared owl, is a medium sized owl endemic to the island of Madagascar. It is sometimes considered to be conspecific with the long-eared owl (Asio otus.) It ranges from 40–50 centimetres (16–20 in) in length, making it the largest of the country's owls; females are larger than males. Its upperparts, crown and nape are brownish-black while its underparts are buff with black streaking. It has a brown facial disk, black bill and orange eyes. Its long ear tufts are dark brown, flecked with tan, matching the head.
