The marail guan or Cayenne guan (Penelope marail) is a species of bird in the family Cracidae, the chachalacas, guans, and curassows.

Müller based his account on "Le Marail" from Cayenne that had been described in 1771 by the French naturalist, the Comte de Buffon in his Histoire Naturelle des Oiseaux. The marail guan is now one of 15 species placed in the genus Penelope that was introduced in 1776 by the German naturalist Blasius Merrem. The specific epithet and the common name are from Marai, the Carib word for a guan.
Two subspecies are recognised: Males weigh 772 to 1,310 g (1.7 to 2.9 lb) and females 770 to 1,450 g (1.7 to 3.2 lb). The back, wings, and central tail feathers of the nominate subspecies are dark with a greenish olive gloss. The outer... Wikipedia →

Possible
About 20% of wildlife watchers report a Marail Guan sighting in Brownsberg Nature Park on a given day, based on 63 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 73rd most-seen of the 221 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 80%, if each day is a fresh chance.
December
In that month about 40% of wildlife watchers report a Marail Guan in Brownsberg Nature Park on a given day, against about 20% in March–April and August–November, the lowest months. May to July have too few records to rate.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Marail Guan 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 Brownsberg Nature Park, in our data
Brownsberg Nature Park is the only park on Wallace's Line with enough records to rate Marail Guan sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Marail Guan is recorded against all the birds logged in Brownsberg Nature Park (63 verified sightings from 2019 to 2026), 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.
