The sarus crane (Grus antigone) is a large nonmigratory crane found in parts of the Indian subcontinent, Southeast Asia, and Australia. The tallest of the flying birds, standing at a height of up to 1.8 m, they are a conspicuous species of open wetlands in South Asia, seasonally flooded Dipterocarpus forests in Southeast Asia, and Eucalyptus-dominated woodlands and grasslands in Australia.
The adult sarus crane is very large, with grey wings and body, a bare red head and part of the upper neck, a greyish crown, and a long, greenish-grey, pointed bill. In flight, the long neck is held straight, unlike that of a heron, which folds it back, and the black wing tips can be seen; the crane's long, pink legs trail behind them. This bird has a grey ear covert patch, orange-red irises, and a greenish-grey bill. Juveniles have a yellowish base to the bill and the brown-grey head is fully feathered.
