The black-crowned antshrike (Thamnophilus atrinucha) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in every Central American country except El Salvador and in Colombia, Ecuador, Peru, and Venezuela.
What is now the black-crowned antshrike was long included as a subspecies of Thamnophilus punctatus, which at that time was called the slaty antshrike. Following the results of a study published in 1997, the slaty antshrike was split into six species. The remnant T. punctatus was named the northern slaty antshrike and the new T. atrinucha was named the western slaty antshrike. By 2012 taxonomists determined that T. atrinucha was not closely related to other slaty antshrikes so its English name was changed to black-crowned antshrike and its position within a linear presentation of genus Thamnophilus was adjusted. The black-crowned and black-hooded antshrike (T. bridgesi) are sister species.

Rare
Under 5% of wildlife watchers report a Western Slaty-Antshrike sighting in Panama City on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 314th most-seen of the 363 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 Western Slaty-Antshrike in Panama City on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Western Slaty-Antshrike sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Panama City, in our data
Panama City is the only city on Wallace's Line with enough records to rate Western Slaty-Antshrike sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Western Slaty-Antshrike is recorded against all the birds logged in Panama City (11 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.
