The Hispaniolan emerald (Riccordia swainsonii) is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is endemic to the island of Hispaniola, which is shared by the Dominican Republic and Haiti.
The Hispaniolan emerald was formerly placed in the genus Chlorostilbon. Based on a molecular phylogenetic study published in 2014 and a 2017 publication, the North American Classification Committee of the American Ornithological Society, the International Ornithological Committee (IOC), and the Clements taxonomy moved it to the resurrected genus Riccordia. However, as of 2020 BirdLife International's Handbook of the Birds of the World (HBW) retained it in Chlorostilbon.
The Hispaniolan emerald is closely related to the Cuban emerald (Riccordia ricordii) and the Puerto Rican emerald (R. maugaeus). It is monotypic. Male Hispaniolan emeralds are 9.5 to 10.5 cm (3.7 to 4.1 in) long and females 8.5 to 9.5 cm (3.3 to 3.7 in). The species weighs between 2.5 and 5 g (0.088 and 0.18 oz). Both sexes have a small white spot behind the eye. Males have a bill whose mandible is red and the maxilla black, and that is slightly... Wikipedia →

Rare
Under 5% of wildlife watchers report a Hispaniolan Emerald sighting in Santo Domingo on a given day, based on 37 verified sightings from GBIF citizen-science data. It is the 64th most-seen of the 110 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.
March–April and November
In those months about 10% of wildlife watchers report a Hispaniolan Emerald in Santo Domingo on a given day, against under 5% in May–October and December–February, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Hispaniolan Emerald sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Santo Domingo, in our data
Santo Domingo is the only city on Wallace's Line with enough records to rate Hispaniolan Emerald sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Trochilidae
The closest relatives of the Hispaniolan Emerald that you can see in Santo Domingo (family Trochilidae, Hummingbirds) are Vervain Hummingbird (about 60%) and Antillean Mango (about 60%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Hispaniolan Emerald is recorded against all the birds logged in Santo Domingo (37 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.
