Ібіс сивоперий Threskiornis melanocephalus

A large wader with a white body and bare black head and neck. Males and females look similar and both have grayish tail feathers. It probes into mud and shallow water with its long, down curved black bill, sometimes submerging its entire head. Found primarily around wetlands including agricultural fields and occasionally around coastal areas, but also seen foraging in dry fields and human-modified landscapes.
