The blackish-grey antshrike (Thamnophilus nigrocinereus) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Brazil, Colombia, French Guiana and Venezuela. The blackish-grey antshrike was described by the English zoologist Philip Sclater in 1855 and given the binomial name Thamnophilus nigrocinereus. It has these five subspecies:
Some authors treated Castelnau's antshrike (T. cryptoleucus) as a subspecies of the blackish-grey antshrike, but that approach was not widely accepted. They are now considered sister species. Some authors suggest that some of the current subspecies might be better treated as species.
The blackish-grey antshrike is 15 to 17 cm (5.9 to 6.7 in) long and weighs 28 to 32 g (0.99 to 1.1 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 sexual dimorphism. Adult males...

Possible
About 20% of wildlife watchers report a Blackish-gray Antshrike sighting in Anavilhanas National Park on a given day, based on 79 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 54th most-seen of the 291 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
June, August–September and November
In those months about 30% of wildlife watchers report a Blackish-gray Antshrike in Anavilhanas National Park on a given day, against about 10% in January, March–April and October, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Blackish-gray Antshrike sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Anavilhanas National Park, in our data
Anavilhanas National Park is the only park on Wallace's Line with enough records to rate Blackish-gray Antshrike sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Blackish-gray Antshrike is recorded against all the birds logged in Anavilhanas National Park (79 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.
