Description
A large, stocky parrot with a short tail. The bird is mostly green with a distinctive yellow patch on the nape of the neck and red patches on the wing bends. Known for their powerful flight and loud, raucous calls.
Colour & Pattern
Dorsal surface is primarily a deep forest green transitioning to a dark, almost black primary cover. The outer web features a vibrant blue-violet iridescence. The ventral side is more matte and grey-green.
Barb Structure
Tightly interlocked pennaceous barbs throughout most of the vane for flight efficiency; the base shows slight plumulaceous (downy) texture
Texture & Surface
Smooth and glossy on the upper surface with a slight oily coating for waterproofing; the vane is stiff and resilient
Key Features
Heavy asymmetry, bicolored vane (green and deep blue-violet), and a thick light-colored rachis characteristic of Psittacidae flight feathers
Habitat
Tropical deciduous forests, gallery forests, and scrubland mangals; also found in agricultural areas with scattered trees
Geographic Range
Pacific coast of Mexico through Central America to northwestern Costa Rica
Ecological Role
Primary seed disperser for many tropical hardwood trees; their messy eating habits allow seeds to drop and germinate away from the parent tree.
Similar Species
Mealy Amazon (Amazona farinosa) feathers are larger and less vibrant; Red-lored Amazon (Amazona autumnalis) feathers have different color distributions on the secondary flight feathers.
Interesting Facts
Yellow-naped Amazons are among the best mimics in the parrot world, capable of perfectly imitating human speech and complex melodies. They are also highly social and long-lived, often reaching 50+ years.
Condition Notes
Good condition; minor fraying on the trailing edge suggests natural wear or 'molt-out' rather than damage from a predator
