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.

With luck
About 10% of wildlife watchers report a Dickcissel sighting in Toluca on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 96th most-seen of the 118 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Dickcissel is recorded against all the birds logged in Toluca (14 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.
