The golden-crowned sparrow (Zonotrichia atricapilla) is a large New World sparrow found in the western part of North America. The golden-crowned sparrow is one of five species in the genus Zonotrichia, a group of large American sparrows. It has no subspecies. It is a sister species with, and very closely related to, the white-crowned sparrow; studies of mitochondrial DNA show the two evolved into separate species very recently in geologic time. The white-throated sparrow is a slightly more distant relative. Hybridization with both white-crowned and white-throated sparrows has been reported.
Ornithologist John Latham first described the species in his book General Synopsis of Birds in 1781, but he thought it was a variety of what he called the "black-crowned bunting" and neglected to give it a scientific name. That lapse was corrected in 1789, when Johann Friedrich Gmelin assigned it the name Emberiza atricapilla in the 13th edition of Systema naturae. Various authorities in the 1800s (including John James Audubon) placed it in the genus Fringilla, but many assigned it to its current genus, Zonotrichia, once William Swainson had established that genus.

Possible
About 30% of wildlife watchers report a Golden-crowned Sparrow sighting in Portland on a given day, based on 13,645 verified sightings from GBIF citizen-science data. It is the 22nd most-seen of the 230 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
October to January
In those months about 50% of wildlife watchers report a Golden-crowned Sparrow in Portland on a given day, against under 5% in June to August, the lowest months. Those are among Portland's wettest months, with about 210 mm of rain a month against 10 mm in July.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Golden-crowned Sparrow sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 12 cities where we can rate Golden-crowned Sparrow sightings, Portland ranks 2nd at about 30%, level with the leaders once rounded. The best odds are in San Francisco (United States, about 30%).
GBIF citizen-science records
It is estimated from how often the Golden-crowned Sparrow is recorded against all the birds logged in Portland (13,645 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.
