The yellow-eyed junco (Junco phaeonotus) is a species of bird in the family Passerellidae, the New World sparrows. It is found from the southwestern United States to Guatemala.

GBIF citizen-science records
It is estimated from how often the Yellow-eyed Junco is recorded against all the birds logged in Toluca (19 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.
