The buff-browed chachalaca (Ortalis superciliaris) is a species of bird in the family Cracidae, the chachalacas, guans, and curassows. It is endemic to Brazil. What is now the buff-browed chachalaca was previously a subspecies of what was then called variable chachalaca (Ortalis motmot). (Confusingly, after the split the International Ornithological Committee (IOC) renamed O. motmot "little chachalaca" but the American Ornithological Society (AOS) and the Clements taxonomy retained the name "variable" for it.) It is monotypic.
The buff-browed chachalaca is the smallest member of genus Ortalis. It is 42 to 46 cm (1.4 to 1.5 ft) long. Its crown, neck, and upper breast are gray and the rest of its upperparts brown. Its lower breast and belly are tan. The central tail feathers are dark green-brown with chestnut tips; the outer ones are chestnut. Unique among Ortalis, it has a prominent supercilium that can be any color from buffy white to pale cinnamon. Its facial skin is dark slate gray.
The buff-browed chachalaca is found in northeastern Brazil south of the Amazon River in parts of the states of Pará, Maranhão... Wikipedia →

Rare
Under 5% of wildlife watchers report a Buff-browed Chachalaca sighting in Belém on a given day, based on 18 verified sightings from GBIF citizen-science data. It is the 94th most-seen of the 144 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
March and June–August
In those months about 10% of wildlife watchers report a Buff-browed Chachalaca in Belém on a given day, against under 5% in April–May and September–February, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Buff-browed Chachalaca sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Belém, in our data
Belém is the only city on Wallace's Line with enough records to rate Buff-browed Chachalaca sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Buff-browed Chachalaca is recorded against all the birds logged in Belém (18 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.
