[2] The white-crested guan is a large bird and grows to a length of about 80 centimetres (31 in).

It has a long crest of white feathers which gives it its name, bluish cheeks, black upper parts glossed with green, dark reddish-brown underparts and a long black tail.

Its range is limited to the south-central and southeastern parts of the Amazon basin, although it just extends across the Rio Araguaia into the Cerrado ecoregion.

[4] The greatest threat faced by the white-crested guan is destruction of its rainforest habitat.

As increasing amounts of forest are cleared and converted into agricultural land and cattle ranches, suitable habitat is reduced.
