Curicaca (Theristicus caudatus)

The Buff-necked Ibis, 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 lower chest, and lacks the contrasting large white wing-patches.
