The giant antshrike (Batara cinerea) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Argentina, Bolivia, Brazil, and Paraguay. The giant antshrike was described by the French ornithologist Louis Pierre Vieillot in 1819 and given the binomial name Thamnphilus cinerea (misspelled as Tamnphilus). The current genus Batara was introduced by the French naturalist René Lesson in 1831.
The giant antshrike is the largest antbird, 27 to 35 cm (11 to 14 in) long and weighing 100 to 155 g (3.5 to 5.5 oz). The species exhibits significant sexual dimorphism, though both sexes have a crest, a very long and wide tail, and a long gray bill with a hook at the end like true shrikes. Adult males of the nominate subspecies have a black forehead, crown, and crest. Their back, wings, and tail are barred with black and white. Their face, nape, throat, and underparts are neutral gray.

Rare
Under 5% of wildlife watchers report a Giant Antshrike sighting in São Paulo on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 333rd most-seen of the 353 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Giant Antshrike in São Paulo on a given day, so our monthly data shows no clear season.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Giant 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 São Paulo, in our data
São Paulo is the only city on Wallace's Line with enough records to rate Giant Antshrike sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Giant Antshrike is recorded against all the birds logged in São Paulo (7 verified sightings), 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.
