The saw-billed hermit (Ramphodon naevius) is a hummingbird in the family Trochilidae. It is endemic to Brazil. The saw-billed hermit is placed in the hermit subfamily Phaethornithinae, but among these birds, it is the species most similar to the typical hummingbirds, Trochilinae. It is the only member of its genus and has no subspecies.
The saw-billed hermit is 14 to 16 cm (5.5 to 6.3 in) long and weighs 5.3 to 9 g (0.19 to 0.32 oz). It is one of the three heaviest hermits and the male is heavier than the female. Both sexes have saw-like serrations on the mandible and the male's bill has a hooked tip as well. (The unrelated tooth-billed hummingbird (Androdon aequatorialis) is the only other hummingbird that has a serrated bill.) Both sexes have scaly brown upperparts and dark and pale striped underparts. They have a reddish ochre throat, a dark patch through the eye, and a white supercilium. The upper side of the tail is purplish black while the underside has progressively more buff at the ends to the outer pair of feathers.
The saw-billed hermit is found in a narrow band of southeastern Brazil from the... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Saw-billed Hermit is recorded against all the birds logged in Santos (116 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.
