The brown jay (Cyanocorax morio) is a large jay native to Central America and southern Texas. The brown jay was formerly placed in its own genus Psilorhinus. When molecular phylogenetic studies found that the genus Cyanocorax was paraphyletic relative to Psilorhinus, Psilorhinus was subsumed into Cyanocorax to resolve the paraphyly.
Brown jays vary in plumage geographically: there are two main groups. Northern birds are almost completely dark brown, with lighter brown on the underparts. Southern birds are white-bellied and have bright white tips to the outer tail feathers. The intergrade zone is in Veracruz, Mexico. Adults in both populations have black bills, legs, and feet. Immatures have yellow bare parts, including yellow eye-rings.

Possible
About 30% of wildlife watchers report a Brown Jay sighting in Biotopo Cerro Cahuí on a given day, based on 161 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 11th most-seen of the 191 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
August
In that month about 50% of wildlife watchers report a Brown Jay in Biotopo Cerro Cahuí on a given day, against about 20% in March and October, the lowest months. That is one of Biotopo Cerro Cahuí's wettest months, with about 170 mm of rain against 25 mm in March.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Brown Jay sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
12th of 35
Of the 35 parks where we can rate Brown Jay sightings, Biotopo Cerro Cahuí ranks 12th at about 30%. The best odds are in Tikal National Park (Guatemala, about 90%), Pico Bonito National Park (Honduras, about 70%) and Calakmul Biosphere Reserve (Mexico, about 70%). All parks ranked.
Same order: Passeriformes
The closest relatives of the Brown Jay that you can see in Biotopo Cerro Cahuí (order Passeriformes, Perching Birds) are Great-tailed Grackle (about 50%), Social Flycatcher (about 50%) and Magnolia Warbler (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Brown Jay is recorded against all the birds logged in Biotopo Cerro Cahuí (161 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.
