The golden-sided euphonia (Euphonia cayennensis) is a species of bird in the family Fringillidae, the finches and euphonias. It is found in northern Brazil, French Guiana, Guyana, Suriname and eastern Venezuela. The golden-sided euphonia was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it in the genus Tanagra and coined the binomial name Tanagra cayennensis. Gmelin's account was based on "Le tangara noir de Cayenne" that had been described in 1760 by the French ornithologist Mathurin Brisson from a specimen that had been collected in French Guiana. The golden-sided euphonia is now placed in the genus Euphonia that was introduced in 1806 by the French zoologist Anselme Desmarest. At the time, the genus Euphonia was a member of the family Thraupidae, the "true" tanagers. Multiple studies in the late twentieth and early twenty-first centuries resulted in Euphonia being reassigned to its present place in the family Fringillidae.
The golden-sided euphonia is monotypic. The golden-sided euphonia is about 11 cm (4.3 in) long and... Wikipedia →

Possible
About 30% of wildlife watchers report a Golden-sided Euphonia sighting in Brownsberg Nature Park on a given day, based on 94 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 40th most-seen of the 221 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
December
In that month about 70% of wildlife watchers report a Golden-sided Euphonia in Brownsberg Nature Park on a given day, against about 20% in August and November, the lowest months. May to July have too few records to rate.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Golden-sided Euphonia sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Brownsberg Nature Park, in our data
Brownsberg Nature Park is the only park on Wallace's Line with enough records to rate Golden-sided Euphonia sightings: about 30% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Golden-sided Euphonia is recorded against all the birds logged in Brownsberg Nature Park (94 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.
