The Bolivian slaty antshrike (Thamnophilus sticturus) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Bolivia, Brazil, and Paraguay. The Bolivian slaty antshrike was described by the Austrian ornithologist August von Pelzeln in 1868 and given its current binomial name Thamnophilus sticturus. It was later treated as a subspecies of T. punctatus, which was then called the slaty antshrike. Following the results of a study published in 1997, the slaty antshrike was split into six species, of which the Bolivian slaty antshrike is one. To avoid confusion the remnant T. punctatus was given its present name of northern slaty antshrike.
The Bolivian slaty antshrike is monotypic. The Bolivian slaty antshrike is about 14 cm (5.5 in) long and weighs 18 to 20 g (0.63 to 0.71 oz). Members of genus Thamnophilus are largish members of the antbird family; all have stout bills with a hook like those of true shrikes. This species exhibits significant sexual dimorphism. Adult males have a gray forehead and a black crown. Their back is gray with a few black spots and a hidden white patch between... Wikipedia →

Rare
Under 5% of wildlife watchers report a Bolivian Slaty-Antshrike sighting in Amboró National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 255th most-seen of the 273 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Bolivian Slaty-Antshrike in Amboró National Park on a given day, so our monthly data shows no clear season. June has too few records to rate.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Bolivian Slaty-Antshrike sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Amboró National Park, in our data
Amboró National Park is the only park on Wallace's Line with enough records to rate Bolivian Slaty-Antshrike sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Thamnophilus
The closest relatives of the Bolivian Slaty-Antshrike that you can see in Amboró National Park (genus Thamnophilus, Typical Antshrikes) are Chestnut-backed Antshrike (about 20%) and Variable Antshrike (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Bolivian Slaty-Antshrike is recorded against all the birds logged in Amboró National Park (6 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.
