The golden-crowned emerald (Cynanthus auriceps) is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is endemic to western Mexico. The golden-crowned emerald was originally described in genus Trochilus. Since then it has variously been classified as a subspecies of what is now Canivet's emerald (Cynanthus canivetii) and included in blue-tailed emerald (Chlorostilbon mellisugus). In 2020 the North American Classification Committee of the American Ornithological Society (AOS), the International Ornithological Committee (IOC), and the Clements taxonomy placed it in genus Cynanthus with Carnivet's emerald, broad-billed hummingbird (C. latirostris), Turquoise-crowned hummingbird (C. doubledayi), and the Cozumel emerald (C. forficatus). The 2020 Version 5 of BirdLife International's Handbook of the Birds of the World retains it in Chlorostilbon.
The golden-crowned emerald is monotypic. The golden-crowned emerald is 7.5 to 9.5 cm (3.0 to 3.7 in) long and weighs about 2.2 g (0.078 oz). The adult male's crown is brilliant golden green and the rest of its upperparts duller golden green to bronzy green. Its... Wikipedia →

Rare
Under 5% of wildlife watchers report a Golden-crowned Emerald sighting in Mexico City on a given day, based on 58 verified sightings from GBIF citizen-science data. It is the 248th most-seen of the 332 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 Golden-crowned Emerald in Mexico City on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Golden-crowned 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 Mexico City, in our data
Mexico City is the only city on Wallace's Line with enough records to rate Golden-crowned Emerald sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Golden-crowned Emerald is recorded against all the birds logged in Mexico City (58 verified sightings), 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.
