The great antshrike (Taraba major) is a passerine bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in southern Mexico, in every Central American country except El Salvador, on Trinidad, and in every mainland South American country except Chile, though only as a vagrant in Uruguay.
The great antshrike was described by the French ornithologist Louis Pierre Vieillot in 1816 and given the binomial name Thamnophilus major. The current genus Taraba was introduced by the French naturalist René Lesson in 1831.
The great antshrike has these ten subspecies: The great antshrike is the only member of genus Taraba. Its closest relatives appear to be the fasciated and bamboo antshrikes of genus Cymbilaimus. The first, found in Central America and mostly west of the Andes, may represent a separate species from the other, which are found east of the Andes. In addition, differences within the members of each group may not be significant enough in some cases to warrant subspecies status... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Great Antshrike is recorded against all the birds logged in Fortaleza (73 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.
