Black-faced Ibis (Theristicus melanopis)

The black-faced ibis is a carnivorous species that feeds by probing in grassy pastures and wetlands, for insects, molluscs, the chicks of small birds, and small mammals such as mice (3) (5). Normally seen in pairs or small groups (7), it nests in rocky gullies, cliffs or woodland, where the female lays and then incubates two eggs for around 28 days before they hatch (5). While T. m. branickii is sedentary, populations of T. m. melanopis in southern Chile and Argentina migrate northwards to the Argentine pampas in the non-breeding season, from April to September (2) (6).
