The bare-faced ibis (Phimosus infuscatus), also known as the whispering ibis, is a species of bird in the family Threskiornithidae, in the monotypic genus Phimosus. It is found in Argentina, Bolivia, Brazil, Colombia, Ecuador, Guyana, Paraguay, Suriname, Uruguay, and Venezuela.
The bare-faced ibis is either dark brown or a blackish color. It is called the bare-faced ibis because it does not have any feathers on its face. It has a long decurved bill with a pinkish to reddish brown colour. The skin on its face is usually a reddish color, and it also has long orange colored beak with pink legs. The total length of the ibis ranges between 45 and 50 cm.
The bare-faced ibis forages in most soil and along the edges of standing water. Its diet consists of insects, worms, clams, and other small invertebrates. The bare-faced ibis occurs in open areas such as wet meadows, savannas, marshes, and rice fields. The ibis is usually near sea level but was recorded in Venezuela and Colombia.
Bare-faced ibises are usually seen in large flocks of their own species or with other species of ibis, sometimes even found with domestic...

GBIF citizen-science records
It is estimated from how often the Bare-faced Ibis is recorded against all the birds logged in Madidi National Park (39 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
