The Andean siskin (Spinus spinescens) is a species of finch in the family Fringillidae. It is found in Colombia, Ecuador, and Venezuela. Its natural habitats are subtropical or tropical moist montane forests, subtropical or tropical high-altitude shrubland, subtropical or tropical high-altitude grassland, and heavily degraded former forest.
This is a small green-and-yellow finch. According to some sources, it is the smallest species of finch on average, although others give this title to the lesser goldfinch. The total length can range from 9.5 to 11 cm (3.7 to 4.3 in). A weight of 11.5 g (0.41 oz) may be at the high end.

The Andean siskin has deep green upperparts with black and yellow coloration on the wings and tail. The adult male has a distinctive black cap.

GBIF citizen-science records
It is estimated from how often the Andean Siskin is recorded against all the birds logged in Farallones de Cali National Natural Park (39 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.
