The Nashville warbler (Leiothlypis ruficapilla) is a small songbird in the New World warbler family, found in North and Central America. It breeds in parts of the northern and western United States and southern Canada, and migrates to winter in southern California and Texas, Mexico, and the north of Central America. It has a gray head and a green back, and its underparts are yellow and white.
The Nashville warbler is a small warbler. Both male and female Nashville warblers have a gray head fading into a greenish back and wings, a white belly and a yellow throat and breast. They have a complete white eye ring, no wing bars, and a thin pointed black bill. Adult males have a rusty brown patch on their crown, which is usually hard to see and often covered by gray feathers. Males will raise it slightly when agitated. Females and immature birds have a duller olive-grey head, and less bold yellow on their throat. The Nashville warbler is closely related to Virginia's warbler, Lucy's warbler, and the Colima warbler, the four sharing generally similar plumage.

With luck
About 10% of wildlife watchers report a Nashville Warbler sighting in León on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 99th most-seen of the 124 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
March
In that month about 30% of wildlife watchers report a Nashville Warbler in León on a given day, against under 5% in January, May, July–September and November, the lowest months. That is one of León's driest months, with about 10 mm of rain against 170 mm in July. June has too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Nashville Warbler sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
12th of 38
Of the 38 cities where we can rate Nashville Warbler sightings, León ranks 12th at about 10%. The best odds are in Puebla (México, about 40%), Mexico City (México, about 30%) and Guadalajara (México, about 30%).
GBIF citizen-science records
It is estimated from how often the Nashville Warbler is recorded against all the birds logged in León (11 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.
