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.

Rare
Under 5% of wildlife watchers report a White-faced Ibis sighting in Guadalajara on a given day, based on 39 verified sightings from GBIF citizen-science data. It is the 101st most-seen of the 184 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
October to December
In those months about 10% of wildlife watchers report a White-faced Ibis in Guadalajara on a given day, against under 5% in January to September, the lowest months. Those are among Guadalajara's driest months, with about 25 mm of rain a month against 210 mm in July.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most White-faced Ibis sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
14th of 32
Of the 32 cities where we can rate White-faced Ibis sightings, Guadalajara ranks 14th at under 5%. The best odds are in León (México, about 30%), Mexico City (México, about 20%) and Toluca (México, about 20%).
Same order: Pelecaniformes
The closest relatives of the White-faced Ibis that you can see in Guadalajara (order Pelecaniformes, Pelicans, Herons, Ibises, and Allies) are Great Egret (about 10%), Green Heron (about 10%) and Black-crowned Night Heron (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the White-faced Ibis is recorded against all the birds logged in Guadalajara (39 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.
