The Amazonian antshrike (Thamnophilus amazonicus) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in every mainland South American country except Argentina, Chile, Paraguay, and Uruguay.
The Amazonian antshrike was described and illustrated by the English zoologist Philip Sclater in 1858 and given its current binomial name Thamnophilus amazonicus. Subspecies T. a. cinereiceps was originally described as a species and some early twentieth century authors maintained that treatment when others recognized it in its current subspecies status. What is now the northern slaty antshrike subspecies T. punctatus huallagae was for a time included as a subspecies of the Amazonian antshrike.
The Amazonian antshrike is 14 to 15 cm (5.5 to 5.9 in) long and weighs 17 to 21 g (0.60 to 0.74 oz). Members of genus Thamnophilus are largish members of the antbird family; all have stout bills with a hook like those... Wikipedia →

Rare
Under 5% of wildlife watchers report an Amazonian Antshrike sighting in Anavilhanas National Park on a given day, based on 13 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 197th most-seen of the 291 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–August and December
In those months about 10% of wildlife watchers report an Amazonian Antshrike in Anavilhanas National Park on a given day, against under 5% in January–April and September–November, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Amazonian 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.
4th of 6
Of the 6 parks where we can rate Amazonian Antshrike sightings, Anavilhanas National Park ranks 4th at under 5%. The best odds are in Brownsberg Nature Park (Suriname, about 30%), Sierra de la Macarena National Park (Colombia, about 10%) and Amacayacu National Natural Park (Colombia, about 10%).
GBIF citizen-science records
It is estimated from how often the Amazonian Antshrike is recorded against all the birds logged in Anavilhanas National Park (13 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.
