The Cozumel emerald (Cynanthus forficatus) is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is endemic to the Mexican island of Cozumel off the Yucatán Peninsula. The Cozumel emerald's taxonomic history is complicated. It was originally described as Chlorostilbon forficatus, then as a subspecies of golden-crowned emerald (now Cynanthus auriceps) which itself has been treated as a subspecies of Canivet's emerald (now Cynanthus canivetii). Other more recent authors include it and many other taxa as subspecies of the blue-tailed emerald (Chlorostilbon mellisugus).
The North American Classification Committee of the American Ornithological Society, the International Ornithological Committee (IOC), and the Clements taxonomy assign it the binomial Cynanthus forficatus. However, as of 2020 BirdLife International's Handbook of the Birds of the World (HBW) retains it in genus Chlorostilbon.
Male Cozumel emeralds are 9 to 10.5 cm (3.5 to 4.1 in) long and females 8 to 9.1 cm (3.1 to 3.6 in). Males and females both weigh about 2.5 g (0.088 oz). Males have a black bill with a red tip. Its crown is bright... Wikipedia →

Very likely
About 70% of wildlife watchers report a Cozumel Emerald sighting in Arrecifes de Cozumel National Park on a given day, based on 1,693 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 9th most-seen of the 205 birds we can rate there. Over three days the chance rises to over 90%, if each day is a fresh chance.
July and November
In those months about 80% of wildlife watchers report a Cozumel Emerald in Arrecifes de Cozumel National Park on a given day, against about 50% in August, the lowest month.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Cozumel Emerald 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 Arrecifes de Cozumel National Park, in our data
Arrecifes de Cozumel National Park is the only park on Wallace's Line with enough records to rate Cozumel Emerald sightings: about 70% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Cozumel Emerald is recorded against all the birds logged in Arrecifes de Cozumel National Park (1,693 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.
