It is the only member of the genus Spiza, though some sources list another supposedly extinct species.
The dickcissel was formally described in 1789 by German naturalist Johann Friedrich Gmelin under the binomial name Emberiza americana. Gmelin based his account on the "black-throated bunting" that the Welsh naturalist Thomas Pennant had described and illustrated in 1785 in his Arctic Zoology. The dickcissel is now the only species placed in the genus Spiza that was introduced in 1824 by French naturalist Charles Lucien Bonaparte. The genus name Spiza is the Ancient Greek word for a common type of finch, now assumed to be a chaffinch. The species is monotypic; no subspecies are recognised.

Rare
Under 5% of wildlife watchers report a Dickcissel sighting in Denver on a given day, based on 171 verified sightings from GBIF citizen-science data. It is the 192nd 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 Dickcissel in Denver on a given day, so our monthly data shows no clear season.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Dickcissel sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
12th of 23
Of the 23 cities where we can rate Dickcissel sightings, Denver ranks 12th at under 5%. The best odds are in Toluca (México, about 10%), Austin (United States, under 5%) and Dallas (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Dickcissel is recorded against all the birds logged in Denver (171 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.
