Black-faced ibis : ウィキペディア英語版 | Black-faced ibis
The black-faced ibis (''Theristicus melanopis'') is a species of bird in the Threskiornithidae family. It is found in grassland and fields in southern and western South America. It has been included as a subspecies of the similar buff-necked ibis, but today all major authorities accept the split. On the contrary, the black-faced ibis includes the taxon ''branickii'' as a subspecies, although some authorities treat it as a separate species, the Andean ibis (''T. branickii''). ==Description== It has a total length of approximately . In the nominate subspecies the head, neck and lower chest are buffish, the crown and nape are cinnamon, the upperparts and (often incomplete) chest-band are grey, the belly and flight feathers are black, and the wing-coverts are whitish (though not contrasting strongly with the grey upperparts). The bill, throat-wattle and bare skin around the eyes are blackish and the legs are red. In the subspecies ''branickii'' the throat-wattle is smaller, the bill is shorter, the wing-coverts are greyer, the lower chest is paler and the cinnamon on the crown and nape is brighter and more extensive. The similar buff-necked ibis is almost entirely restricted to warm regions, has contrasting large white wing-patches, a dark grey (not buff) lower chest, and its throat-wattle is smaller than in ''T. m. melanopis''.
