The black-throated hermit (Phaethornis atrimentalis) is a species of hummingbird in the family Trochilidae. It is found in Colombia, Ecuador, and Peru. The black-throated hermit was for a time considered a subspecies of little hermit (P. longuemareus), but is more closely related to the reddish hermit (P. ruber) and grey-chinned hermit (P. griseogularis).
The black-chinned hermit is about 9 to 10 cm (3.5 to 3.9 in) long, with P. a. riojae being larger than the nominate. The species has generally greenish upperparts with a reddish rump and a white-tipped dark tail. The throat is dark brown and the rest of the underparts cinnamon red but for whitish undertail coverts. Males often have a dark band between the throat and breast. Females are similar to males but their throat is lighter and they generally have longer wings.
The nominate subspecies of black-chinned hermit is found in the eastern Andes of Colombia, Ecuador, and northern Peru's Loreto department. P. a. riojae is found further south, in central Peru between the departments of... Wikipedia →

Rare
Under 5% of wildlife watchers report a Black-throated Hermit sighting in Yasuní National Park on a given day, based on 42 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 401st most-seen of the 533 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Black-throated Hermit in Yasuní National Park on a given day, so our monthly data shows no clear season.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Black-throated Hermit sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 3 parks where we can rate Black-throated Hermit sightings, Yasuní National Park ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Cuyabeno Wildlife Reserve (Ecuador, under 5%) and Sierra de la Macarena National Park (Colombia, under 5%).
Same genus: Phaethornis
The closest relatives of the Black-throated Hermit that you can see in Yasuní National Park (genus Phaethornis, Typical Hermits) are Great-billed Hermit (about 10%), White-bearded Hermit (about 10%) and Straight-billed Hermit (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black-throated Hermit is recorded against all the birds logged in Yasuní National Park (42 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.
