PLUMBEOUS IBIS Theristicus caerulescens
The Plumbeous Ibis is a thick-necked bird with a long, downcurved bill and a honking goose-like call. Though not strictly tied to water like many ibis, it is more numerous in boggy areas and flooded fields, where it hunts frogs, small vertebrates and large invertebrates. They are usually encountered alone or in pairs, but in winter when resources are tight, they may gather in loose aggregations of 30 or more birds.
