Sandhill Crane
Antigone canadensis
Adults are gray overall; during breeding, their plumage is usually much worn and stained, particularly in the migratory populations, and looks nearly ochre. The average weight of the larger males is 4.57 kg (10.1 lb), while the average weight of females is 4.02 kg (8.9 lb), with a range of 2.7 to 6.7 kg (6.0 to 14.8 lb) across the subspecies. Sandhill cranes have red foreheads, white cheeks, and long, dark, pointed bills. In flight, their long, dark legs trail behind, and their long necks keep straight. Immature birds have reddish-brown upper parts and gray underparts.

Sarus Crane
Antigone antigone
The adult sarus crane is very large, with grey wings and body, a bare red head, collar and nape, 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. The bare red skin of the adult's head and neck is brighter during the breeding season.
