The scaly-breasted hummingbird or scaly-breasted sabrewing (Phaeochroa cuvierii) is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is found in Belize, Colombia, Costa Rica, Guatemala, Honduras, Mexico, Nicaragua, and Panama.
Most major taxonomic systems place the scaly-breasted hummingbird by itself in genus Phaeochroa. However, BirdLife International's Handbook of the Birds of the World (HBW) places it in the large genus Campylopterus and calls it the scaly-breasted sabrewing. All but HBW follow the findings of a 2014 study that found Campylpterus to be polyphyletic and resulted in the move of several species to other genera.
The worldwide systems agree that the scaly-breasted hummingbird has these six subspecies: The scaly-breasted hummingbird is 11.5 to 13 cm (4.5 to 5.1 in) long and weighs about 8 to 10 g (0.28 to 0.35 oz). All of the subspecies... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Scaly-breasted Hummingbird is recorded against all the birds logged in Arenal Volcano National Park (5,635 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.
