The chestnut-crowned becard (Pachyramphus castaneus) is a species of bird in the family Tityridae, the tityras, becards, and allies. It is found in Argentina, Bolivia, Brazil, Colombia, Ecuador, Peru, Paraguay, and Venezuela.
The chestnut-crowned becard was originally described in 1827 as Tityra castenea. It was eventually reassigned to genus Pachyramphus that the English zoologist George Robert Gray erected in 1839. The genus Pachyramphus has variously been assigned to the tyrant flycatcher family Tyrannidae and the cotinga family Cotingidae. Several early twenty-first century studies confirmed the placement of Pachyramphus in Tityridae and taxonomic systems made the reassignment. In 1998 the American Ornithological Society was unsure where to place the genus and listed its members as incertae sedis but in 2011 moved them to Tityridae.
The chestnut-crowned becard and the cinnamon becard (P. cinnamomeus) are sister species and form a superspecies. The chestnut-crowned becard has these five subspecies: Wikipedia →

Any time of year
In every month with enough records, under 5% of wildlife watchers report a Chestnut-crowned Becard in São Paulo on a given day, so our monthly data shows no clear season.

GBIF citizen-science records
It is estimated from how often the Chestnut-crowned Becard is recorded against all the birds logged in São Paulo (31 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.
