The berylline hummingbird (Saucerottia beryllina) is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is found in El Salvador, Guatemala, Honduras, Mexico, and the southern United States.
The berylline hummingbird was formerly placed in the genus Amazilia. A molecular phylogenetic study published in 2014 found that the genus Amazilia was polyphyletic. In the revised classification to create monophyletic genera, the berylline hummingbird was moved by most taxonomic systems to the resurrected genus Saucerottia. However, BirdLife International's Handbook of the Birds of the World retains it in Amazilia.
The berylline hummingbird has five subspecies: The berylline hummingbird primarily inhabits arid landscapes. The wide variety includes dense oak and pine-oak forest, scrublands, deciduous and thorn forest, gallery forest, plantations, and parks and gardens. In elevation it is found from near sea level to the submontane zone, though it is most common between 500 and 1,800 m (1,600 and 5,900 ft).
The berylline hummingbird is 8 to 10 cm (3.1 to 3.9 in) long. Males weigh... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Berylline Hummingbird is recorded against all the birds logged in Reserva de la Biosfera Mariposa Monarca (20 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.
