Overview

Overview

The Keel-billed Toucan inhabits tropical lowland forests from southern Mexico through Central America into northern South America. Its multicolored bill is one of the most recognizable features of any Neotropical bird.

  • Ranges from southern Mexico to Colombia and Venezuela
  • Bill shows a distinctive rainbow of greens, oranges, and reds
  • Often travels in small, noisy social groups

Identifying the Feather

Feather Identification

Keel-billed Toucan feathers combine deep black with a bright yellow chest patch.

  • Body: glossy black feathers over most of the body
  • Chest and face: bright lemon-yellow feathers
  • Undertail coverts: red
  • Rump: white, visible in flight
  • Bill: not feathered, but its green base shading to orange and red tip is a key identification aid alongside plumage

The yellow chest patch, paired with the multicolored bill, distinguishes this species from the Toco Toucan's plain orange bill and white (not yellow) chest.

Plumage & Molt

Plumage Details

Sexes look alike, both black-bodied with a yellow chest and red undertail coverts. Juveniles have duller, less vividly colored bills and slightly less crisp plumage contrast. A single annual molt maintains the bold coloration.

Habitat & Range

Habitat & Range

Found from southern Mexico through Central America to Colombia and Venezuela, inhabiting tropical lowland and foothill rainforest, forest edges, and clearings with fruiting trees. It is generally resident within its forested range.

Behavior & Field Notes

Behavior & Field Notes

Keel-billed Toucans feed primarily on fruit, supplemented by insects and occasionally eggs or small vertebrates, using the long bill to reach fruit on outer branches. They nest in tree cavities, often former woodpecker holes. Their call is a repeated, frog-like croaking note. Small social groups are often seen moving together through the forest canopy. The yellow chest and multicolored bill are the clearest identification features for this species.
