The black-throated gray warbler or black-throated grey warbler (Setophaga nigrescens) is a passerine bird of the New World warbler family Parulidae. It is 13 cm (5.1 in) long and has gray and white plumage with black markings. The male has the bold black throat of its name, and black stripes on its head, as well as black streaks on its flanks; the female is a paler version of the male, with a white throat and less distinct black markings on the flanks and wings. It breeds in western North America from British Columbia to New Mexico, and winters in Mexico and the southwestern United States. The habitats it prefers are coniferous and mixed forests and scrubland, especially those with pinyon pines, junipers, sagebrush, and oaks. Its nest is an open cup of plant fibers lined with feathers, built a few metres from the ground in the branches of a tree or shrub. Three to five eggs are laid, and young are fed by both parents. Common in its breeding range, it does not seem to be seriously threatened by human activities, unlike many migratory warblers.
The black-throated gray warbler was first described by John Kirk Townsend in 1837 from a specimen collected near today's Portland... Wikipedia →

With luck
About 10% of wildlife watchers report a Black-throated Gray Warbler sighting in Sacramento on a given day, based on 764 verified sightings from GBIF citizen-science data. It is the 95th most-seen of the 235 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
September
In that month about 30% of wildlife watchers report a Black-throated Gray Warbler in Sacramento on a given day, against under 5% in May–July and November–March, the lowest months. That is one of Sacramento's driest months, with almost no rain against 120 mm in December.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Black-throated Gray Warbler sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 23 cities where we can rate Black-throated Gray Warbler sightings, Sacramento ranks 9th at about 10%, level with the leaders once rounded. The best odds are in Mexico City (México, about 10%), Guadalajara (México, about 10%) and Vancouver (Canada, about 10%).
Same genus: Setophaga
The closest relatives of the Black-throated Gray Warbler that you can see in Sacramento (genus Setophaga, Setophaga Warblers) are Yellow-rumped Warbler (about 60%), Audubon'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 Black-throated Gray Warbler is recorded against all the birds logged in Sacramento (764 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.
