The white-throated sparrow (Zonotrichia albicollis) is a passerine bird of the New World sparrow family Passerellidae. It breeds in northern North America and winters in the southern United States.

He used the current English name. Edwards based his hand-coloured etching on a "neat drawing in colours" supplied by the American naturalist William Bartram from Philadelphia in Pennsylvania. When the German naturalist Johann Friedrich Gmelin revised and expanded Carl Linnaeus's Systema Naturae in 1789 he included the white-throated sparrow. He placed it with the finches in the genus Fringilla and coined the binomial name Fringilla albicollis. The white-throated sparrow is now one of five American sparrows placed in the genus Zonotrichia that was introduced by William Swainson in 1832. The genus name is from Ancient Greek ζωνη (zōnē) meaning "band" and θριξ (thrix), τριχος (trikhos) meaning "hair". The specific epithet albicollis combines Latin albus meaning "white" with Modern Latin -collis meaning... Wikipedia →

GBIF citizen-science records
It is estimated from how often the White-throated Sparrow is recorded against all the birds logged in Portland (1,264 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.
