A male is typically 90–105 cm (2 ft 11 in – 3 ft 5 in) tall, with a length of around 115 cm (3 ft 9 in) and has a 2.1–2.7 m (6 ft 11 in – 8 ft 10 in) wingspan. The male can range in weight from 5.8 to 18 kg (13 to 40 lb). The heaviest verified specimen, collected in Manchuria, was about 21 kg (46 lb), a world record for heaviest flying bird. In a study in Spain, one male weighed as much as 19 kg (42 lb). Larger specimens have been reported but remain unverified.
