Description
This is a sleek, black secondary wing feather from the American Crow. The bird is entirely black, including the bill and legs, with a heavy bill and a fanshaped tail in flight. They are known for their 'caw-caw' vocalizations and highly social, intelligent behavior.
Colour & Pattern
Uniformly iridescent black on the dorsal surface with a subtle violet or blue sheen in direct light. The ventral (under) side is a duller, matte charcoal gray. The very base of the barbs near the calamus is pale gray.
Barb Structure
Densely interlocked pennaceous barbs throughout most of the vane, giving it a solid wind-resistant surface. The base shows loose, gray plumulaceous (downy) barbs for insulation.
Texture & Surface
Smooth and glossy on the upper surface due to structural coloration; the vane feels stiff and resilient. The trailing edge is slightly more flexible than the leading edge.
Key Features
Solid black coloration with iridescent sheen; rounded tip; gray downy base; 7+ inch length; lack of white or brown markings characteristic of other large birds.
Habitat
Extremely versatile; found in open woodlands, agricultural fields, city parks, suburban yards, and shorelines. They generally avoid unbroken dense forests.
Geographic Range
Ubiquitous across North America from southern Canada throughout the United States to northern Mexico. Most populations are year-round residents.
Ecological Role
Omnivorous scavengers and predators; they play a vital role in cleaning up carrion and controlling insect populations. They are also known to track food sources for other predators.
Similar Species
Common Raven (larger, more pointed feathers, oily sheen); Fish Crow (nearly identical, requires measurements/location); Black Vulture (much larger, silver-gray undersides).
Interesting Facts
Crows are among the most intelligent animals on Earth, capable of using tools, recognizing individual human faces, and mourning their dead in 'funerals'.
Condition Notes
Good condition. There is minor fraying at the very tip and along the trailing edge (distal end), suggesting some wear prior to molting. No visible fault bars or parasite damage.
