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.

Possible
About 30% of wildlife watchers report a White-faced Ibis sighting in León on a given day, based on 26 verified sightings from GBIF citizen-science data. It is the 45th most-seen of the 124 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
December
In that month about 50% of wildlife watchers report a White-faced Ibis in León on a given day, against about 10% in May and July, the lowest months. That is one of León's driest months, with about 5 mm of rain against 170 mm in July. June has too few records to rate.
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.
Yes
Of the 32 cities where we can rate White-faced Ibis sightings, León has the highest daily chance: about 30%. Next come 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 León (order Pelecaniformes, Pelicans, Herons, Ibises, and Allies) are Great Egret (about 50%), Snowy Egret (about 40%) and American White Pelican (about 30%), 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 León (26 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.
