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 →

Rare
Under 5% of wildlife watchers report a Black-throated Gray Warbler sighting in Denver on a given day, based on 36 verified sightings from GBIF citizen-science data. It is the 248th most-seen of the 299 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 Black-throated Gray Warbler in Denver 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 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.
23rd of 23
Of the 23 cities where we can rate Black-throated Gray Warbler sightings, Denver ranks 23rd at under 5%. The best odds are in Mexico City (México, about 10%), Guadalajara (México, about 10%) and Vancouver (Canada, about 10%).
Same genus: Setophaga

GBIF citizen-science records
It is estimated from how often the Black-throated Gray Warbler is recorded against all the birds logged in Denver (36 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.
