Buff-necked ibis : ウィキペディア英語版 | Buff-necked ibis
The buff-necked ibis (''Theristicus caudatus''), also known as the white-throated ibis, is a fairly large ibis found widely in open habitats of eastern and northern South America. It formerly included the similar black-faced ibis as a subspecies, but that species is almost entirely restricted to colder parts of South America, has a buff (not dark grey) lower chest, and lacks the contrasting large white wing-patches. ==Description== It has a total length of approximately . The neck is buffish, the upperparts are grey, the belly and flight feathers are black, and there is a large white patch in the wings. In flight, where the relatively short legs do not extend beyond the tail (unlike e.g. ''Eudocimus'' and ''Plegadis''), the white patch forms a broad white band on the upperwing that separates the black remiges and the grey lesser wing-coverts. The bill and bare skin around the eyes are blackish and the legs are red.
