Description
This feather belongs to a Common Grackle, a large, lanky blackbird with a long tail and a piercing yellow eye. Although they appear black from a distance, their feathers are actually a kaleidoscope of iridescent purples, blues, and bronzes. They are social birds often seen in large, noisy flocks, known for their harsh 'rusty hinge' calls and confident, strutting gait on lawns.
Colour & Pattern
The feather features a dark brownish-black soot base with a striking metallic green-to-bronze iridescent sheen on the outer vane. This is a structural color, meaning it changes based on the angle of light.
Barb Structure
The distal half is pennaceous and tightly interlocked for insulation and protection, while the proximal base is plumulaceous (downy) for heat retention.
Texture & Surface
Glossy and silky on the iridescent distal portion, transitioning to a soft, matte, and fluffy texture at the base. The surface is smooth to reduce friction.
Key Features
Small size, rounded tip, and distinct metallic green/bronze iridescence on a dark melanin base.
Habitat
Open woodlands, marshes, agricultural fields, suburban lawns, and city parks. They are highly adaptable to human-altered landscapes.
Geographic Range
Resident or migratory across North America, east of the Rocky Mountains, from southern Canada to the Gulf Coast.
Ecological Role
Omnivorous foragers that act as both pest controllers (eating insects) and seed dispersers, though they can sometimes impact grain crops. They are a resilient species with stable populations.
Similar Species
European Starling (shorter, more pointed feathers with buff tips), Brewer's Blackbird (more uniform blue/purple sheen), and Brown-headed Cowbird (less iridescence).
Interesting Facts
Common Grackles are known for 'anting,' a behavior where they rub ants on their feathers. The formic acid secreted by the ants is thought to act as a natural pesticide against feather mites.
Condition Notes
Excellent condition; the barbs are mostly intact with minimal fraying, suggesting it was recently molted or shed. No visible fault bars or parasite damage.
