The green-backed firecrown (Sephanoides sephaniodes) is a hummingbird in the "coquettes", tribe Lesbiini of subfamily Lesbiinae. It is found in Argentina, mainland Chile, and the Juan Fernández Islands. The green-backed firecrown is monotypic. It shares its genus only with the Juan Fernandez firecrown (S. fernandensis). The specific epithet sephaniodes is sometimes misspelled sephanoides to match the genus.
The green-backed firecrown is 10 to 10.5 cm (3.9 to 4.1 in) long. Males weigh about 5.5 g (0.19 oz) and females about 5 g (0.18 oz). The species is sexually dimorphic, with larger, short-billed males, and smaller, longer-billed females. Adults of both sexes have bronzy green upperparts, slaty green wings and tails, and pale buff underparts with black and green spots. Adult males have the eponymous iridescent red-yellow crown. Juveniles of both sexes have rusty feather edges on the head and their underparts have a cinnamon tone. Because the young are sexually monochromatic, it is difficult to assign a sex to them.
The green-backed firecrown is found in Chile from south of the Atacama Region all the way... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Green-backed Firecrown is recorded against all the birds logged in Santiago (5,625 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.
