Green Hermit

Overview

The Green Hermit is one of the larger hermit hummingbirds, ranging from Costa Rica through Panama into northern South America, where it occupies the shaded understory of humid forest. Its greenish body tone and long, drooping bill are typical of the hermit group.

Both sexes are similar, showing dull green upperparts and grayish underparts, with a strongly decurved bill and a long central tail streamer tipped in white.

Feather Identification

• Body feathers: Dull to bronzy green above, grayish or buffy below, without bright iridescent patches
• Tail feathers: Central pair notably elongated into a narrow streamer with a white tip, a signature hermit trait
• Facial feathers: Often show a dark mask bordered by pale stripes above and below the eye
• Shaft color: Dark above, paler on underparts
• Size: Larger-bodied than many hermits, with a proportionally long, curved bill
• Similar species: Similar to Long-billed Hermit but generally greener and slightly smaller; best separated by range and subtle underpart tone differences

Plumage Details

Adults show greenish upperparts, grayish-buff underparts, and a dark facial mask bordered by pale stripes, with an elongated white-tipped central tail streamer. Sexes appear alike. Juveniles resemble adults but show a shorter tail streamer and duller overall tones until reaching maturity. No strong seasonal plumage variation is documented.

Habitat & Range

Green Hermits inhabit the shaded understory of humid lowland and foothill forest from Costa Rica and Panama south through parts of northern South America, including Colombia, Venezuela, and Trinidad. The species is resident, with individuals following regular trap-line routes between flowering plants rather than undertaking long-distance migration.

Behavior & Field Notes

This hermit feeds on nectar from a variety of understory flowers along established trap-lines and supplements its diet with small insects gleaned from vegetation or caught in flight. Males display at communal leks, producing repetitive, high-pitched songs to attract mates. Nests are cone-shaped structures attached to the underside of large leaves, often near streams. Field observers most often detect this species by its persistent, monotonous song from the forest understory.
