The species is restricted to the lowland grasslands of India, Nepal, and Cambodia with fewer than 1,000 mature individuals. To assess the species status in Koshi Tappu Wildlife Reserve, Nepal, we repeated our frst comprehensive survey conducted during the 2012 breeding season. In spite of a larger area coverage we recorded only 41 adult Bengal Floricans in 2017 compared to 47 individuals in 2012. Detectability of this rare species is low in its Imperata-Saccharum grasslands. We, therefore, used a long pole with black and white clothing to mimic Bengal Florican’s display fight to stmulate male Bengal Florican. The number of adult males recorded was the same as in the 2012 survey and the adult male density remains one of the highest in the Indian subcontnent. Management recommendatons for the long-term conservaton of the species in Koshi Tappu include maintenance of Imperata-Saccharum grasslands in the reserve favoured by the Bengal Florican and working with farmers and communites adjacent to the reserve where the birds breed in order to maintain some agricultural lands with vegetaton height suitable for the species especially during the species’ breeding season.
