Townsend's warbler (Setophaga townsendi) is a small songbird of the New World warbler family. Townsend's warbler was formally described in 1837 by the American naturalist John Kirk Townsend under the binomial name Sylvia townsendi. The type locality is Fort Vancouver on the Columbia River in the state of Washington. After the merger of the genera Dendroica and Setophaga, Townsend's warbler is now placed in the genus Setophaga that was introduced by the English naturalist William Swainson in 1827. The species is monotypic: no subspecies are recognised.
Townsend's warbler has a yellow face with a black stripe across its cheeks extending into an ear patch, a thin pointed bill, two white wing bars, olive upperparts with black streaks on their backs and flanks, and a white belly. Adult males have a black cap, black throat and yellow lower breast; females have a dark cap and a yellow throat. Immature birds are similar to females with a dark green cap and cheeks.
Their breeding habitats are coniferous forests with large trees on the northwestern coast of North America. Their nests are shallow cups built with grass and lined with moss. These... Wikipedia →

Rare
Under 5% of wildlife watchers report a Townsend's Warbler sighting in Toronto on a given day, based on 19 verified sightings from GBIF citizen-science data. It is the 121st most-seen of the 288 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
November and December
In those months about 10% of wildlife watchers report a Townsend's Warbler in Toronto on a given day, against under 5% in January to October, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Townsend's Warbler sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
15th of 28
Of the 28 cities where we can rate Townsend's Warbler sightings, Toronto ranks 15th at under 5%. The best odds are in Toluca (México, about 40%), San Francisco (United States, about 20%) and Tijuana (México, about 20%).
Same genus: Setophaga
The closest relatives of the Townsend's Warbler that you can see in Toronto (genus Setophaga, Setophaga Warblers) are Yellow Warbler (about 20%), Northern Yellow Warbler (about 20%) and Yellow-rumped Warbler (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Townsend's Warbler is recorded against all the birds logged in Toronto (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.
