Adults have a yellow to greenish yellow bill and a small yellow to orange-yellow frontal shield, though these colors may further vary.

Immature birds have a dusky olive bill, greenish gray legs and feet, gray-brown upperparts, and paler underparts than adults. Juveniles are dark drab gray with dusky mottling on a white head and neck.

Rare
Under 5% of wildlife watchers report a White-winged Coot sighting in Santiago on a given day, based on 25 verified sightings from GBIF citizen-science data. It is the 89th most-seen of the 110 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-winged Coot in Santiago on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most White-winged Coot sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
6th of 6
Of the 6 cities where we can rate White-winged Coot sightings, Santiago ranks 6th at under 5%. The best odds are in Santa Cruz de la Sierra (Bolivia, about 30%), Buenos Aires (Argentina, about 20%) and Cordoba (Argentina, about 10%).
GBIF citizen-science records
It is estimated from how often the White-winged Coot is recorded against all the birds logged in Santiago (25 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.
