The Tennessee warbler (Leiothlypis peregrina) is a New World warbler that breeds in eastern North America and winters in southern Central America, the Caribbean, and northern South America. The specific name peregrina is from Latin peregrinus "wanderer".
The Tennessee warbler is 11.5 cm (4.5 in) long, has a 19.69 cm (7.75 in) wingspan, and weighs roughly 10 g (0.35 oz). The breeding male has olive back, shoulders, rump and vent. The flight feathers are brownish-black. It has a slate gray neck, crown and eyeline. The underside is a gray-white. The female is similar to the male, but is much duller and is tinged with yellow and olive overall, especially on the underside. The Tennessee warbler has long wings, short tail and a thin, pointy bill. Juveniles and first-year birds are quite similar to the female. In winter and fall, adult male resembles juvenile and spring adult female but shows more yellow below: the grey neck and crown turn into an olive green while the underside takes a yellow hue. On the face the yellow supraocular line stands out. Both sexes have white undertail coverts all year long.

GBIF citizen-science records
It is estimated from how often the Tennessee Warbler is recorded against all the birds logged in Calgary (1,524 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.
