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.

Rare
Under 5% of wildlife watchers report a Dickcissel sighting in Dallas on a given day, based on 208 verified sightings from GBIF citizen-science data. It is the 125th most-seen of the 253 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
May
In that month about 10% of wildlife watchers report a Dickcissel in Dallas on a given day, against under 5% in June to April, the lowest months. That is one of Dallas's wettest months, with about 120 mm of rain against 55 mm in July.
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.

GBIF citizen-science records
It is estimated from how often the Dickcissel is recorded against all the birds logged in Dallas (208 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.
