Long-billed Hermit

Phaethornis longirostris

The Long-billed Hermit, Phaethornis longirostris, is a member of the hummingbird family, Trochilidae. This avian jewel is adorned with greenish-brown upperparts and a spectrum of brownish to grayish hues on the underparts. The central tail feathers are notably elongated, tipped with white, and the bird's bill is distinctively long and decurved, with the female's bill being slightly shorter and more curved than the male's.

Identification Tips

To identify the Long-billed Hermit, look for its characteristic long, decurved bill and the unique pattern of dark and light ochre bands on its uppertail coverts. The males, weighing between 5 to 7.5 grams, are slightly heavier than the females, who tip the scales at 4 to 6.5 grams. The subspecies vary slightly in coloration, with some showing more ochraceous underparts or duller green upperparts.


The Long-billed Hermit thrives in the understory and edges of various landscapes, including rainforests, tall secondary forests, humid semi-deciduous forests, cloudforests, and gallery forests. It is an adaptable species, found from sea level up to 2,500 meters in northern Colombia, demonstrating a broad altitudinal range.


This species is distributed from central Mexico, through Central America, and into South America, reaching as far south as Peru. It is divided into four subspecies, each with its own geographic range, from Mexico's Oaxaca and Chiapas states to Peru's Tumbes and Piura departments.


The Long-billed Hermit is known for its "trap-line" feeding behavior, visiting a circuit of flowering plants for nectar. It also consumes small arthropods. While not known for large-scale movements, it may wander short distances.

Song & calls

The vocalizations of the Long-billed Hermit include a series of piercing, upslurred 'sweeup' notes for the northern subspecies, while the song of P. l. baroni consists of continuous chipping notes. Calls are typically sharp and explosive, often given in flight.


Breeding seasons vary by location, with nests being cone-shaped cups suspended from leaves. Clutch size is two eggs, with an incubation period of 17 to 18 days and fledging occurring 22 to 23 days post-hatch. Males engage in communal lek singing and tail-wiggling displays to attract females.

Similar Species

The Long-billed Hermit was once considered conspecific with the Long-tailed Hermit, P. superciliosus, but they have since been split into separate species.

Diet and Feeding

The diet consists primarily of nectar from a variety of flowering plants, including Heliconia, Costus, Aphelandra, and Passiflora, supplemented by small arthropods.

Conservation status

The IUCN classifies the Long-billed Hermit as Least Concern, with population sizes and trends currently unknown. Some subspecies, such as P. l. susurrus, have small ranges that could pose risks, while others are fairly common and occur in protected areas.

Love this app and has helped me to identify more birds. The challenges and badges are great for keeping the motivation going to get out and keep birding.
Really great app
It’s easy to use and it’s fun to log the birds you notice on a walk or just in your garden. There’s a option to record the birds you see in a session which is really nice. Good excuse to stop for a while and just watch birds. I am also enjoying the information part where you can find out fact about birds from all over the world.

Very wholesome app: I joined this app with a new interest in watching birds to help me find out what I was spotting. The community is very active in helping identify birds which is great and everyone is very kind so it’s just a nice wholesome community. I would definitely recommend this for any bird spotter 😃
Great app for beginner twitchers
I’ve had a passion of photographing birds for a long time now but have only just gotten into proper birdwatching, and this app is brilliant for those just getting started. There is a great sense of community among users and the app is very easy to use and professional. Awesome app altogether
Just what birding needs
We need more fun in birding, for years it has had a reputation for being up tight and stuffy and only perused by retirees and anoraks. Birda helps change that perception and firmly brings birding into the 21st century! Fun, interactive while still contributing to science and conservation. If you aren’t on it, why not??
Fantastic app - Love it!
Love this app and have used it almost daily. Lots of species information and easy to use. Love seeing birds spotted by other users in the UK and worldwide.
