The hermit warbler (Setophaga occidentalis) is a small perching bird. It is a species of New World warbler or wood-warbler. They are a migratory bird, the breeding range spanning the majority of the west coast of the United States. Their winter range includes parts of Mexico and Central America as well as parts of the southern California coast.
Hermit warblers are dark gray in coloration on top, and white below, and their flanks are streaked with black. The wings have two diagonal white wing bars. The majority of the hermit warbler's head is yellow, and males have a dark black throat, while females have much less black on their throat bib and immature birds have no black throat. Both males and females measure 5.5 inches (14 cm) in length, 0.3 to 0.5 oz (8.5 to 14.2 g) in weight, and 7.9 in (20 cm) in wingspan.
Like most warblers the hermit warbler eats a strict diet of insects and spiders, and can often be found hanging upside-down from the ends of conifer branches, like a chickadee, probing for food. Nests are neat and cup-shaped, constructed from stems, grass, twigs, and pine needles positioned near the tip of a branch... Wikipedia →

Rare
Under 5% of wildlife watchers report a Hermit Warbler sighting in El Vizcaíno Biosphere Reserve on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 230th most-seen of the 237 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
October
In that month about 10% of wildlife watchers report a Hermit Warbler in El Vizcaíno Biosphere Reserve on a given day, against under 5% in November to September, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Hermit Warbler sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
11th of 17
Of the 17 parks where we can rate Hermit Warbler sightings, El Vizcaíno Biosphere Reserve ranks 11th at under 5%. The best odds are in Yosemite National Park (United States, about 20%), Sequoia and Kings Canyon National Parks (United States, about 20%) and Reserva de la Biosfera Mariposa Monarca (Mexico, about 20%).
Same genus: Setophaga
The closest relatives of the Hermit Warbler that you can see in El Vizcaíno Biosphere Reserve (genus Setophaga, Setophaga Warblers) are Yellow-rumped Warbler (about 30%), Yellow Warbler (about 10%) and American Redstart (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Hermit Warbler is recorded against all the birds logged in El Vizcaíno Biosphere Reserve (5 verified sightings from 2019 to 2026), 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.
