The Bare-faced Ibis is a small, dull ibis of open marshes throughout much of South America. It is smaller, and shorter-legged, than any other Neotropical ibis. Gregarious, this species forms flocks of up to several hundred individuals, and often commutes to and from roost sites in long lines and "V's". Seasonal movements generally are related to rainfall. The Bare-faced Ibis feeds in wet meadows and muddy areas, probing with its long, decurved bill. It occurs from northern Colombia east through the Venezuelan llanos and from eastern Brazil west to Bolivia and south to central Argentina.
