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).

The nominate subspecies of the black-faced ibis is mainly found in southern South America, ranging throughout most of southern and central Argentina and Chile, where it occurs from sea-level to an altitude of approximately 2,500 metres (8,200 ft). It also occurs very locally in coastal Peru. While it remains fairly common in Argentina and Chile, this subspecies has now been almost entirely extirpated from the Peruvian part of its range.

The subspecies branickii is restricted to altitudes of 3,000 to 5,000 metres (9,800 to 16,400 ft) in the Andean highlands of Bolivia, Peru and Ecuador. It is generally uncommon, and formerly also occurred in Lauca in far northern Chile.

Overall the species is not threatened, and consequently assigned Least Concern by the IUCN. source
