The Sooretama slaty antshrike (Thamnophilus ambiguus) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is endemic to Brazil. The Sooretama slaty antshrike was described by the English naturalist William Swainson in 1825 and given its current binomial name Thamnophilus ambiguus. 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 Sooretama slaty antshrike is one. To avoid confusion the remnant T. punctatus was given its present name of northern slaty antshrike.
The Sooretama slaty antshrike is monotypic. The Sooretama slaty antshrike is 14 to 15 cm (5.5 to 5.9 in) long. 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 black forehead and crown with a few gray spots on the former. Their back is gray with a black spot in the middle and a hidden white patch between the scapulars... Wikipedia →

Rare
Under 5% of wildlife watchers report a Sooretama Slaty-Antshrike sighting in Tijuca National Park on a given day, based on 80 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 122nd most-seen of the 214 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.
January and April–May
In those months about 10% of wildlife watchers report a Sooretama Slaty-Antshrike in Tijuca National Park on a given day, against under 5% in February–March and June–December, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Sooretama 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.
Among the best
Of the 2 parks where we can rate Sooretama Slaty-Antshrike sightings, Tijuca National Park ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Serra dos Órgãos National Park (Brazil, under 5%).
GBIF citizen-science records
It is estimated from how often the Sooretama Slaty-Antshrike is recorded against all the birds logged in Tijuca National Park (80 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.
