The green-tailed emerald (Chlorostilbon alice) is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is endemic to Venezuela. The green-tailed emerald was originally described as Trochilus alice and later moved to its present genus Chlorostilbon. The South American Classification Committee of the American Ornithological Society, the International Ornithological Committee (IOC), and the Clements taxonomy recognize it as a monotypic species. However, BirdLife International's Handbook of the Birds of the World treats it as a subspecies of the short-tailed emerald, (C. poortmani). At least one author has suggested that it is a subspecies of narrow-tailed emerald (C. stenurus).
The male green-tailed emerald is 7.5 to 8.5 cm (3.0 to 3.3 in) long and females 6.5 to 7.5 cm (2.6 to 3.0 in). The species weighs between 3 and 4 g (0.11 and 0.14 oz). Both sexes have a short, straight, black bill. The male's forehead and crown are shining dark green, its upperparts bronzy green, its tail glittering bronze-green, and its underparts grass green. The female's upperparts are like the male's. It has a white line behind... Wikipedia →

Rare
Under 5% of wildlife watchers report a Green-tailed Emerald sighting in Caracas on a given day, based on 138 verified sightings from GBIF citizen-science data. It is the 135th most-seen of the 295 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Green-tailed Emerald in Caracas 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 Green-tailed Emerald sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Caracas, in our data
Caracas is the only city on Wallace's Line with enough records to rate Green-tailed 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 Green-tailed Emerald is recorded against all the birds logged in Caracas (138 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.
