The grey crowned crane is about 1 m (3.3 ft) tall, weighs 3.5 kg (7.7 lbs), and has a wingspan of 2 m (6.5 ft). Its body plumage is mainly grey. The wings are predominantly white, but contain feathers with a range of colours, with a distinctive black patch at the very top. The head has a crown of stiff golden feathers. The sides of the face are white, and there is a bright red inflatable throat pouch. The bill is relatively short and grey, and the legs are black. They have long legs for wading through the grasses. The feet are large, yet slender, adapted for balance rather than defence or grasping. The sexes are similar, although males tend to be slightly larger. Young birds are greyer than adults, with a feathered buff face.
