Wikipedia Abstract

The little bustard (Tetrax tetrax) is a large bird in the bustard family, the only member of the genus Tetrax. The genus name is from Ancient Greek and refers to a gamebird mentioned by Aristophanes and others. It breeds in southern Europe and in western and central Asia. Southernmost European birds are mainly resident, but other populations migrate further south in winter. The central European population once breeding in the grassland of Hungary became extinct several decades ago.
