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 Rocky Mountain National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 201st most-seen of the 223 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a White-faced Ibis in Rocky Mountain National Park on a given day, so our monthly data shows no clear season.
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.
22nd of 23
Of the 23 parks where we can rate White-faced Ibis sightings, Rocky Mountain National Park ranks 22nd at under 5%. The best odds are in Iberá National Park (Argentina, about 20%), Death Valley National Park (United States, about 10%) and El Vizcaíno Biosphere Reserve (Mexico, about 10%).
GBIF citizen-science records
It is estimated from how often the White-faced Ibis is recorded against all the birds logged in Rocky Mountain National Park (9 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.
