The glacier finch (Idiopsar speculifer), also known as the white-winged diuca finch and glacier bird, is a species of bird in the tanager family Thraupidae. It is found in Peru, Bolivia and far northern Chile and Argentina. Its natural habitat is subtropical or tropical high-altitude grassland, where it favours wet boggy ground. It is one of the few birds that have been recorded as nesting in high altitude glaciers, hence its alternative name "the glacier bird". The nest is a bulky structure in the form of a cup, made of grass, twigs and feathers: it can weigh up to half a pound, and may be laid directly on the ice. Two eggs are laid in April or May; the young leave the nest in June or July.

Likely
About 50% of wildlife watchers report a White-winged Diuca-Finch sighting in Lauca National Park on a given day, based on 536 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 16th most-seen of the 112 birds we can rate there. Over three days the chance rises to about 90%, and over a week to over 90%, if each day is a fresh chance.
January, April and June–July
In those months about 60% of wildlife watchers report a White-winged Diuca-Finch in Lauca National Park on a given day, against about 40% in February, May and August–September, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most White-winged Diuca-Finch sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Lauca National Park, in our data
Lauca National Park is the only park on Wallace's Line with enough records to rate White-winged Diuca-Finch sightings: about 50% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the White-winged Diuca-Finch is recorded against all the birds logged in Lauca National Park (536 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.
