Long-billed Hermit

Overview

The Long-billed Hermit is a large member of the hermit hummingbird group, found in the understory of lowland and foothill rainforest from southern Mexico through Central America into northwestern South America. Like other hermits, it lacks the bright iridescent gorgets of many hummingbirds, relying instead on its distinctive shape and buffy tones for identification.

Both sexes are similar, showing bronze-green upperparts, buffy underparts, and a long, strongly decurved bill suited to probing tubular flowers in the forest understory.

Feather Identification

• Body feathers: Bronze-green above, buffy-cinnamon below, without bright iridescent patches
• Tail feathers: Central pair elongated into a narrow streamer tipped in white, distinctive among hermits
• Rump feathers: Often show a rufous or cinnamon tone
• Shaft color: Pale, especially on the buffy underpart feathers
• Size: Larger than many hermit species, with a notably long, decurved bill relative to head size
• Similar species: Similar to Green Hermit but larger overall with buffier underparts; distinguished from smaller hermits by its greater size and longer tail streamer

Plumage Details

Adults show bronze-green upperparts, buffy-cinnamon underparts, and a rufous-tinged rump, with an elongated white-tipped central tail streamer. Sexes look alike, a common trait among hermit hummingbirds. Juveniles are similar but with less defined buffy tones and a shorter tail streamer until maturity. There is no notable seasonal plumage change.

Habitat & Range

Long-billed Hermits inhabit the understory of humid lowland and foothill rainforest from southern Mexico through Central America and into western Colombia and Ecuador. The species is resident, though individuals may make local movements following the bloom cycles of understory flowers along established feeding routes known as trap-lines.

Behavior & Field Notes

This hermit feeds on nectar from a variety of understory flowers along regular trap-line routes, and also gleans small insects and spiders from foliage. Unlike territorial hummingbirds, hermits generally do not defend flowers but instead visit a circuit of scattered blooms. Males gather at communal display sites called leks, where they sing repetitive, high-pitched songs to attract females. Nests are cone-shaped, suspended from the underside of large leaves.
