The blue-vented hummingbird (Saucerottia hoffmanni) is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is found in Costa Rica and Nicaragua. The blue-vented hummingbird was formerly placed in the genus Amazilia as a subspecies of the steely-vented hummingbird (then Amazilia saucerottei, now Saucerottia saucerottei). A molecular phylogenetic study published in 2014 found that the genus Amazilia was polyphyletic. In the revised classification to create monophyletic genera, most taxonomic systems accepted the blue-vented hummingbird as a separate species and moved it to the resurrected genus Saucerottia. However, BirdLife International's Handbook of the Birds of the World (HBW) retains it as the steely-vented subspecies Amazilia saucerottei hoffmanni.
The blue-vented hummingbird is monotypic. The blue-vented hummingbird is 8 to 11 cm (3.1 to 4.3 in) long and weighs an average of 4.45 g (0.16 oz). Both sexes have a straight bill with a blackish maxilla and a coral-red mandible with a dark tip. Adult males have golden-green upperparts with coppery to purplish rump and uppertail coverts.

GBIF citizen-science records
It is estimated from how often the Blue-vented Hummingbird is recorded against all the birds logged in San José (2,530 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.
