Plumbeous Ibis Theristicus caerulescens

  • © Cláudio Dias Timm

The Plumbeous Ibis is a distinctive, stocky ibis of the South American pampas. Adults are uniform dark blue-gray, with a bushy crest, a white forehead, red legs, a reddish eye, and a long, decurved gray bill. This species is found in open, grassy habitats, both dry and wet, from Bolivia and central Brazil south to northern Argentina and Uruguay. Singles or paris forage for insects and molluscs by probing mud with its bill. Pairs are also solitary nesters, building a platform of twigs in a tree near water.
