The White-faced Ibis (Plegadis chihi) is a wading bird in the ibis family Threskiornithidae.

Winter Quintana, Texas

This species breeds colonially in marshes, usually nesting in bushes or low trees. Its breeding range extends from the western USA south through Mexico, as well as from southeastern Brazil and southeastern Bolivia south to central Argentina, and along the coast of central Chile. Its winter range extends from southern California and Louisiana south to include the rest of its breeding range.

Description

Non-breeding plumage

The White-faced Ibis is very similar to the Glossy Ibis in its non-breeding plumages, but it tends to be slightly smaller and the plumage color is somewhat warmer. Breeding adults have a pink bare face bordered with white feathers (rather than a bluish bare face with no bordering feathers), a grey bill, and brighter colored, redder legs. Adults have red eyes year-round, whereas Glossy Ibises have dark eyes. Juveniles of the two species are nearly identical.[2]

Distribution

The White-faced Ibis occurs in Canada, the United States, Central America and the southern half of South America.[1] It seems that this was originally an Old World species and seems to have arrived in the United States in 1817. By the beginning of the 20th century, it was established around the Gulf of Mexico and in Florida but there were still only about fifty breeding pairs in the mid 1930s. A decade later it had reached Long island and Louisiana. By the 1980s, it had spread to much of the southeastern United States and the Atlantic Coast with a few birds reaching the Greater Antilles, Costa Rica and northern Venezuela.[2] In 2012, the total population size was estimated to be 1.2 million individuals, and increasing. The IUCN rates it as being of "Least Concern".[1]
