The bright-rumped yellow finch (Sicalis uropygialis) is a species of bird in the family Thraupidae. It is found in the Puna grassland: Peru, Bolivia and northern Chile and Argentina. Its natural habitats are subtropical or tropical high-altitude grassland and heavily degraded former forest.
The bright-rumped yellow finch was formally described in 1837 by the French naturalists Alcide d'Orbigny and Frédéric de Lafresnaye from a specimen collected in the Bolivian Andes. They coined the binomial name Emberiza uropigyalis. Wikipedia →

With luck
About 10% of wildlife watchers report a Bright-rumped Yellow Finch sighting in Lauca National Park on a given day, based on 86 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 75th most-seen of the 112 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
January
In that month about 30% of wildlife watchers report a Bright-rumped Yellow Finch in Lauca National Park on a given day, against under 5% in July to September, the lowest months. That is one of Lauca National Park's wettest months, with about 150 mm of rain against almost none in May.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Bright-rumped Yellow 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 Bright-rumped Yellow Finch sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Bright-rumped Yellow Finch is recorded against all the birds logged in Lauca National Park (86 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.
