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.

Rare
Under 5% of wildlife watchers report a Brown Jay sighting in Celaque National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 183rd most-seen of the 193 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
May, August–September and November
In those months about 10% of wildlife watchers report a Brown Jay in Celaque National Park on a given day, against under 5% in June–July, October and December–April, the lowest months. Those are among Celaque National Park's wettest months, with about 280 mm of rain a month against 60 mm in February.
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.
27th of 35
Of the 35 parks where we can rate Brown Jay sightings, Celaque National Park ranks 27th at under 5%. 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 family: Corvidae
The closest relatives of the Brown Jay that you can see in Celaque National Park (family Corvidae, Crows, Jays, and Magpies) are Bushy-crested Jay (about 60%), Steller's Jay (about 10%) and Unicolored Jay (about 10%), 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 Celaque National Park (9 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.
