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 Rincón de la Vieja National Park on a given day, based on 22 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 228th most-seen of the 341 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
October
In that month about 10% of wildlife watchers report a Western Slaty-Antshrike in Rincón de la Vieja National Park on a given day, against under 5% in November to September, the lowest months. That is one of Rincón de la Vieja National Park's wettest months, with about 380 mm of rain against 45 mm in February.
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.
17th of 22
Of the 22 parks where we can rate Western Slaty-Antshrike sightings, Rincón de la Vieja National Park ranks 17th at under 5%. The best odds are in Soberanía National Park (Panama, about 50%), Darién National Park (Panama, about 50%) and Cahuita National Park (Costa Rica, about 50%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Western Slaty-Antshrike is recorded against all the birds logged in Rincón de la Vieja National Park (22 verified sightings from 2019 to 2026), 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.
