Migrations are not long-distance, however, and probably are restricted to a few dozen kilometers. Similarly, the terai population seems to move to warmer lowland locations in winter. This species is mostly resident on its breeding grounds around Tonle Sap in Cambodia however, the birds use grasslands near the lake to breed, and move away from the water in the wet season when the breeding grunds are flooded. The South East Asian population occurs in Cambodia and perhaps adjacent southern Vietnam. The former occurs from Uttar Pradesh ( India ) through the terai of Nepal to Assam (where it is called ulu mora) and Arunachal Pradesh in India, and historically to Bangladesh. It has two disjunct populations, one in the Indian subcontinent, another in South East Asia. The latter have almost white wing coverts however, resembling the males' wing patch. The females are similar, and young Bengal Floricans can be easily mistaken for female Lesser Floricans. This is a smaller, slimmer-necked bustard overall, and its males have cheek-tufts of plumes with pennant -like tips rather than the crest, and a white band between neck and back. The only bird even remotely similar to adult males of the Bengal Florican are their counterpart from the Lesser Florican (Sypheotides indica). Displaying males croak and produce a strange deep humming. They are normally silent but when disturbed utters a metallic chik-chik-chik call. Their wing coverts are lighter than the remiges and covered in fine dark barring. įemales are larger than the males and have a buff-brown colour similar to the males' back, with a dark brown crown and narrow dark streaks down the side of the neck. The feet and legs are yellow, the bill and irides are dark. In flight, the male's wings appear entirely white except for the dark primary remiges.

The upperside is buff with fine black vermiculations and black arrowhead markings, and there is a conspicuous large white patch from the wing coverts to the remiges. Its head carries a long lanky crest, and the neck has elongated display plumes. The male has black plumage from the head and neck to underparts. Īdult male taking flight in Kaziranga National Park, Assam ( India )Īdult Bengal Floricans range from 66–68 centimetres (26–27 in) in length. This threatened species is almost extinct probably less than 1,000 and perhaps as few as 500 adult birds are still alive. It is the only member of the genus Houbaropsis. The Bengal Florican or Bengal Bustard, Houbaropsis bengalensis, is a very rare bustard species from tropical southern Asia.
