Otis tarda

The great bustard is the only living member of its genus. A male is typically 90–105cm tall and about 115cm long, with a 2.1–2.7m wingspan and a weight ranging from 5.8 to 18kg (one Spanish male weighed up to 19kg). The adult male is brown above barred with blackish and white below, with a long grey neck and head; immature birds resemble the female (Wikipedia, general species account).

It breeds in open grassland and farmland from northern Morocco and South and Central Europe to temperate Central and East Asia. European populations are mainly resident, while Asian populations migrate farther south in winter. Since 1998 the Great Bustard Group has helped reintroduce it to Salisbury Plain in England (Wikipedia, general species account).
