The white-faced ibis (Plegadis chihi) is a wading bird in the ibis family, Threskiornithidae. This species breeds colonially in marshes, usually nesting in bushes or low trees. Its breeding range extends from southwestern Canada and the western United States 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.
In its non-breeding plumage, the white-faced ibis is very similar to the glossy ibis except that it tends to be slightly smaller and its plumage has a somewhat warmer color. 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.

GBIF citizen-science records
It is estimated from how often the White-faced Ibis is recorded against all the birds logged in Mexico City (2,318 verified sightings), 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.
