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.

With luck
About 10% of wildlife watchers report a White-faced Ibis sighting in Curitiba on a given day, based on 202 verified sightings from GBIF citizen-science data. It is the 62nd most-seen of the 247 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
January
In that month about 30% of wildlife watchers report a White-faced Ibis in Curitiba on a given day, against about 10% in March–June and August–November, the lowest months. That is one of Curitiba's wettest months, with about 220 mm of rain against 75 mm in August.
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.
5th of 32
Of the 32 cities where we can rate White-faced Ibis sightings, Curitiba ranks 5th at about 10%. The best odds are in León (México, about 30%), Mexico City (México, about 20%) and Toluca (México, about 20%).
Same family: Threskiornithidae

GBIF citizen-science records
It is estimated from how often the White-faced Ibis is recorded against all the birds logged in Curitiba (202 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.
