Several other species including the five-striped sparrow (Amphispizopsis quinquestriata) and what are now Bell's sparrow (Artemisiospiza belli) and the sagebrush sparrow (Artemisiospiza nevadensis) were previously also assigned to Amphispiza. These reassignments left the black-throated sparrow as the only member of the genus. They were adopted by the American Ornithological Society (AOS), the IOC, the Clements taxonomy, and AviList. However, as of late 2025 BirdLife International's Handbook of the Birds of the World (HBW) retains the five-striped sparrow in Amphispiza with the black-throated.
The black-throated sparrow's further taxonomy is unresolved. The IOC, AviList, and HBW assign it these nine subspecies: The Clements taxonomy adds a tenth subspecies, A. b. carmenae (Van Rossem,... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Black-throated Sparrow is recorded against all the birds logged in Denver (34 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.
