Mauritius owl
The extinct Mauritius owl (''Mascarenotus sauzieri''), also called Commerson's, Sauzier's or Newton's owl, was endemic to the Mascarene island of Mauritius. It is known from a collection of subfossil bones from the Mare aux Songes swamp, a detailed sketch made by de Jossigny in 1770, a no less detailed description by Desjardins of a bird shot in 1836, and a number of brief reports about owls, the first being those of Van Westzanen in 1602 and Matelief in 1606.
==Taxonomy==
No descriptions of owls were recorded between the mid-17th and the late 18th century. This led to considerable confusion, especially since the bones were referred to ear tuft-less ''Strix'' or barn owls, whereas the image and the description unequivocally show the presence of ear tufts. Thus, it was for a long time believed that 2 or even 3 species of owls occurred on the island. The supposed "barn owl" ''Tyto newtoni'' was described from tarsometatarsus bones of what probably was a male individual of this species, whereas the Mauritius owl's type specimen seems to be a bone of a larger female bird. But the bird was neither a ''Strix'' nor a Scops owl, and certainly not a barn owl. Instead, the Mascarene owls of the genus ''Mascarenotus'' were most probably a distinct evolutionary lineage related to the genus ''Ninox'' that evolved convergently to Scops or ''Asio'' owls. The Mauritius bird was the largest species of its genus, with a total length of about 60 cm. Its scientific name honors Théodore Sauzier, who made the first bones available for scientific study.
