The rusty-margined guan (Penelope superciliaris) is a species of bird in the family Cracidae, which includes the chachalacas, guans, and curassows. It is found in Argentina, Bolivia, Brazil, and Paraguay. The International Ornithological Committee (IOC) and the Handbook of the Birds of the World taxonomies recognize the four rusty-margined guan subspecies listed in the box to the right. The Clements taxonomy does not recognize P. s. pseudonyma as separate but includes its population in the nominate subspecies. Birds in Brazil's Alagoas state are distinctive and might be a separate subspecies. The rusty-margined guan and the Marail guan (P. marail) form a superspecies.

The species' upperparts are dark olive to brownish with the eponymous reddish margins on the wing coverts and scapulars. The belly is also rusty. The face is pale with a supercilium whose color ranges from white to buff or ochre in the different subspecies. P. s. jacupemba paler overall than the nominate... Wikipedia →

Any time of year
In every month with enough records, under 5% of wildlife watchers report a Rusty-margined Guan 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 Rusty-margined Guan is recorded against all the birds logged in São Paulo (16 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.
