Grace's warbler (Setophaga graciae) is a small New World warbler that specializes in pine woods. Grace's warbler was discovered by Elliott Coues in the Rocky Mountains in 1864.

Grace's warblers breed from the south-western United States to Nicaragua and winter in their breeding range from north-eastern Sinaloa and north-western Durango south. They are almost always found in pine forests, even in migration, though at the northern end of their range (in southern Nevada and Utah and southwestern Colorado) they... Wikipedia →

Rare
Under 5% of wildlife watchers report a Grace's Warbler sighting in San Francisco on a given day, based on 195 verified sightings from GBIF citizen-science data. It is the 268th most-seen of the 375 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Grace's Warbler in San Francisco on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Grace'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.
6th of 8
Of the 8 cities where we can rate Grace's Warbler sightings, San Francisco ranks 6th at under 5%. The best odds are in Guatemala City (Guatemala, about 20%), Toluca (México, about 10%) and Guadalajara (México, under 5%).
Same genus: Setophaga
The closest relatives of the Grace's Warbler that you can see in San Francisco (genus Setophaga, Setophaga Warblers) are Yellow-rumped Warbler (about 40%), Townsend's Warbler (about 20%) and Northern Yellow Warbler (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Grace's Warbler is recorded against all the birds logged in San Francisco (195 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.
