The long-tailed hermit (Phaethornis superciliosus) is a large hummingbird that is a resident breeder in Venezuela, the Guianas, and north-eastern Brazil. This species was formerly referred to as the eastern long-tailed hermit.
The long-tailed hermit was formally described by the Swedish naturalist Carl Linnaeus in 1766 in the twelfth edition of his Systema Naturae under the binomial name Trochilus superciliosus.

The specific epithet is from Latin superciliosa meaning "eye-browed". The long-tailed hermit is now the type species of the genus Phaethornis that was introduced in 1827 by William Swainson.
Two subspecies are recognised: The taxonomic history of this group is complicated, with similar hermit populations from both sides of the Andes being originally classed as a single long-tailed hermit species. The western population... Wikipedia →

Rare
Under 5% of wildlife watchers report an Eastern Long-tailed Hermit sighting in Anavilhanas National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 240th most-seen of the 291 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
November
In that month about 10% of wildlife watchers report an Eastern Long-tailed Hermit in Anavilhanas National Park on a given day, against under 5% in December to October, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Eastern Long-tailed 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.
2nd of 2
Of the 2 parks where we can rate Eastern Long-tailed Hermit sightings, Anavilhanas National Park ranks 2nd at under 5%. The best odds are in Brownsberg Nature Park (Suriname, about 60%).
GBIF citizen-science records
It is estimated from how often the Eastern Long-tailed Hermit is recorded against all the birds logged in Anavilhanas National Park (8 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.
