Emerald Toucanet

Aulacorhynchus prasinus

Feather type
Dense contour feathers, short rounded wings
Colours
Overall emerald green with a chestnut-maroon tail tip; some populations show a blue-tinged throat
Bird size
Jay-sized, ~30-35 cm

Overview

Overview

The Emerald Toucanet is a compact, green-plumaged toucan found across a broad swath of montane forest from Mexico south through Central America and into parts of the northern Andes. Unlike the boldly patterned lowland toucans, it relies on cryptic green plumage suited to a shaded, leafy environment.

  • Overall green plumage is unusual among toucans and aids camouflage
  • Widespread across montane cloud forest habitats
  • Regional populations vary in throat color and bill tone, reflecting past treatment as multiple species

Identifying the Feather

Feather Identification

Most body feathers are a rich emerald green, with a slight blue wash on the throat in some populations. The tail is tipped in chestnut or maroon-brown, providing the clearest contrast against the otherwise green plumage.

  • Body: uniform emerald green, feathers with a soft sheen rather than strong iridescence
  • Throat: whitish to pale blue depending on population
  • Tail tip: chestnut to rufous-brown, a useful field mark on shed tail feathers
  • Bill: bicolored, dark above and yellow to pale below in most populations

The uniform green body plumage combined with a chestnut tail tip helps separate this species from other similarly sized green toucanets in overlapping ranges.

Plumage & Molt

Plumage Notes

Sexes look alike in plumage, both showing the same green body and chestnut tail tip. Juveniles are duller and greener overall, lacking the crisper throat contrast of adults, with a shorter, less vividly colored bill.

  • Sexes are not distinguishable by plumage color
  • Juveniles show muted tones and a plainer throat
  • No sharp seasonal plumage change; molt is gradual

Habitat & Range

Habitat & Range

Occupies humid montane and cloud forest from Mexico through Central America and into the northern Andes, generally at higher elevations than the large lowland toucans.

  • Non-migratory resident within its elevational range
  • Prefers dense, humid forest with abundant epiphytes and fruiting trees
  • Some populations shift short distances altitudinally with the seasons

Behavior & Field Notes

Behavior & Field Notes

Emerald Toucanets forage in pairs or small groups, taking fruit along with occasional small animal prey found while moving through the canopy and mid-story.

  • Voice: a repeated, croaking or grunting call, softer than that of large toucans
  • Nesting: natural tree cavities or old woodpecker holes in montane forest trees
  • Field notes: the all-green body plumage combined with a chestnut tail tip is the quickest way to confirm this species over other cloud-forest toucans

Frequently asked questions

Why is this toucan mostly green?

Its plumage matches the shaded, leafy environment of humid montane cloud forest, unlike the boldly patterned lowland toucans.

What is the best feather clue for this species?

Uniform emerald-green body plumage paired with a chestnut or maroon-tipped tail is the most reliable combination.

Do throat colors vary across its range?

Yes, some regional populations show a blue-washed throat while others are paler, reflecting past classification as separate species.

Where would you encounter this species?

In humid montane and cloud forest from Mexico through Central America and into parts of the northern Andes.
