Keel-billed Toucan (Rainbow-billed Toucan)

This sleek, dark flight feather belongs to the Keel-billed Toucan, iconic for its massive, multi-colored bill and bright yellow chest contrasting sharply with its jet-black body plumage. A large, social bird that flies in small flocks across the canopy in short, undulating dips.

Deep glossy blackish-blue hue on the upper surface with subtle iridescence under light; dark brownish-black ventral side with a pale, semitranslucent calamus/base.

Pennaceous along the main vane with tightly interlocked barbs; slight plumulaceous downy structure at the base near the calamus.

Smooth, slightly stiff, with a glossy, light-reflecting sheen typical of tropical canopy frugivores.

Glossy black color with subtle bluish sheen, asymmetrical flight vane structure, pale calamus base, and size (~15 cm) consistent with Neotropical Ramphastos toucans.

Tropical rainforest canopy, lowland moist forests, forest edges, and secondary growth woodland.

Neotropical distribution stretching from Southern Mexico through Central America (including Panama) down to northern Colombia.

Vital seed disperser for tropical rainforest trees due to its diet dominated by large forest fruits.

Chestnut-mandibled Toucan (Ramphastos ambiguus swainsonii) - very similar dark flight feathers but slightly larger; Black-mandibled Toucan; Crested Guan feathers (duller brown/black).

Despite their huge bill size, toucan bills are lightweight and made of hollow spongy bone lined with keratin; they use them to regulate body temperature akin to an elephant's ears.

Fair to Good; shows typical signs of wear and separation along the trailing barb edges, likely a naturally molted feather.

Found in a Barro Colorado island in Panama
