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 →

Possible
About 30% of wildlife watchers report a White-throated Sparrow sighting in Boston on a given day, based on 18,203 verified sightings from GBIF citizen-science data. It is the 24th most-seen of the 283 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.
April and October–December
In those months about 50% of wildlife watchers report a White-throated Sparrow in Boston on a given day, against under 5% in June to August, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most White-throated Sparrow sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
7th of 33
Of the 33 cities where we can rate White-throated Sparrow sightings, Boston ranks 7th at about 30%. The best odds are in New York City (United States, about 60%), Philadelphia (United States, about 50%) and Baltimore (United States, about 50%).
GBIF citizen-science records
It is estimated from how often the White-throated Sparrow is recorded against all the birds logged in Boston (18,203 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.
