Description

This specimen is a drab olive-grey flight feather from the Keel-billed Toucan. While famous for its bright yellow chest and large, multicolored bill, many of its wing feathers are muted dark green-brown or brownish-black to provide camouflage in the forest canopy.

Colour & Pattern

Uniform olive-brown to charcoal grey tone across the vane, fading into a pale, translucent quill base.

Barb Structure

Densely packed pennaceous barbs forming a smooth, cohesive surface; plumulaceous base near the calamus.

Rachis & Barb Pattern

A light-colored, slender central shaft with closely spaced, parallel barbs extending at a uniform angle.

Texture & Surface

Smooth, slightly stiff, and non-reflective matte finish.

Feather Placement

Wing feather, specifically an inner secondary or primary covert.

Key Features

Uniform brownish-olive coloration, asymmetric flight vane structure, pale stiff rachis, and absence of bold bars or spots.

Habitat

Tropical humid lowland forests, forest edges, and second-growth woodlands.

Geographic Range

Southeastern Mexico through Central America into northern Colombia.

Ecological Role

Key seed disperser for large fruit-bearing tropical trees in Central American rainforests.

Similar Species

Chestnut-mandibled Toucan (Ramphastos swainsonii) feathers are virtually identical in dull flight feather coloration, but typically slightly larger.

Interesting Facts

The Keel-billed Toucan is the national bird of Belize. Despite its giant bill, it flies weakly in short spurts, relying heavily on hopping between branches.

Cultural Significance

Toucans hold significant cultural importance in Neotropical indigenous art and folklore; feathers were traditionally used in ceremonial adornments.

Field Identification Tips

Look along forest trails and under fruiting trees in Panama during the annual molt period (post-breeding season).

Condition Notes

Good condition; intact vane with minor fraying near the base and a clean calamus.

Found in Gamboa, Panama
