Plumage Coloration
Its head, neck and lower chest are buffish; its crown and nape are cinnamon; its upperparts and often incomplete chest-band are grey; its belly and flight feathers are black; and its wing-coverts are whitish, which does not create a strong contrast with the grey upperparts.

Similar Species Distinction
The similar buff-necked ibis, which is almost entirely restricted to warm regions, has contrasting large white wing-patches, dark grey rather than buff lower chest, and a smaller throat-wattle than this black-faced ibis subspecies.
Core Distribution Range
The black-faced ibis is mainly found in southern South America, ranging across most of southern and central Argentina and Chile, where it occurs from sea level up to an altitude of approximately 2,500 metres (8,200 ft).
Peruvian Distribution
It also occurs in very localized areas of coastal Peru.
Regional Population Status
It remains fairly common in Argentina and Chile, but the species has now been almost entirely extirpated from the Peruvian portion of its range.
IUCN Conservation Status
Overall, the species is not threatened, so the IUCN has assigned it the Least Concern conservation status.
