The Yucatan jay (Cyanocorax yucatanicus) is a species of bird in the family Corvidae, the crows and their allies. It is native to the Yucatán Peninsula where its habitats are subtropical or tropical dry forest, plantations and cleared areas at altitudes up to 250 m (820 ft). Adults are about 30 cm (12 in) long, black, with blue wings, mantle, and tail, black bills, yellow eye rings and legs. Immature birds have yellow bills. This is a common species of jay with a wide range and the International Union for Conservation of Nature has rated its conservation status as being of "least concern".
The Yucatan jay was first described by the naturalist Alphonse Dubois in 1875. It originally places in the genus Cyanocitta, and was given the scientific name Cyanocitta yucatanica. It is now placed by the genus Cyanocorax, which was introduced by the German zoologist Friedrich Boie in 1826, as Cyanocorax yucatanicus. In 1934, ornithologist Carl Eduard Hellmayr reorganized the genus Cyanocorax and split it into four subgenera. The Yucatan jay was placed into the subgenus Cissilopha as Cissilopha yucatanica. This is now considered a synonym for the Yucatan jay.

Rare
Under 5% of wildlife watchers report a Yucatán Jay sighting in Tikal National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 275th most-seen of the 300 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Yucatán Jay in Tikal National Park on a given day, so our monthly data shows no clear season.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Yucatán 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.
5th of 5
Of the 5 parks where we can rate Yucatán Jay sightings, Tikal National Park ranks 5th at under 5%. The best odds are in Sian Ka'an Biosphere Reserve (Mexico, about 60%), Calakmul Biosphere Reserve (Mexico, about 20%) and Ría Lagartos Biosphere Reserve (Mexico, about 10%).
GBIF citizen-science records
It is estimated from how often the Yucatán Jay is recorded against all the birds logged in Tikal 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.
