The green hermit (Phaethornis guy) is a large hummingbird that is a resident breeder from southern Central America (Costa Rica and Panama) south to northern South America (north-eastern Venezuela and Trinidad, and the northern Andes of eastern Peru)
It is 13.5 cm (5.3 in) long and weighs 6.3 g (0.22 oz). The male is mainly dark green with a blue-green rump. It has a dark mask through the eye, with buff stripes above and below this, and down the centre of the throat. The central feathers of the tapered tail are—for large hermit—relatively short and white-tipped, and are wiggled in display at the communal leks. The reddish bill is long and decurved. The female is sooty gray (rather than green) below, with an even longer bill and a much longer tail. The call of this species is a loud zurk, and the males' lekking "song" is a repeated swark.
The nominate subspecies Phaethornis guy guy is found in Venezuela and Trinidad. The western P. g. apicalis of the American Cordillera is slightly smaller and the sexes more similar. This hermit inhabits forest undergrowth, usually near water, and prefers hilly areas. It seems to favor primary rainforest... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Green Hermit is recorded against all the birds logged in Arenal Volcano National Park (4,147 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.
