Description
This is a sturdy flight feather from an American Crow, a large all-black passerine known for its intelligence. The bird typically has a wingspan of 33-39 inches and is famous for its 'caw-caw' vocalizations and social communal roosting behavior.
Colour & Pattern
Uniformly iridescent black/dark charcoal. The upper surface shows a subtle violet or greenish sheen in direct light (structural color), while the underside is more matte grey-black. No banding or spots present.
Barb Structure
Tightly interlocked pennaceous barbs throughout most of the vane for aerodynamic integrity, transitioning to a small plumulaceous (downy) section at the very base of the calamus.
Texture & Surface
Smooth, stiff, and slightly glossy on the dorsal side. The trailing edge is flexible, while the leading edge is rigid to withstand air pressure.
Key Features
Uniform black coloration with iridescent sheen, significant vane asymmetry, and a stiff, dark rachis. Lack of white or grey bases distinguishes it from some raptors.
Habitat
Highly adaptable; found in open woodlands, agricultural fields, orchards, shorelines, city parks, and suburban yards.
Geographic Range
Widespread across most of North America, from southern Canada to northern Mexico. Permanent resident in most of its range, with some northern populations moving south for winter.
Ecological Role
Omnivorous scavenger and predator; they play a vital role in cleaning up carrion and controlling insect populations, though they also impact songbird nests.
Similar Species
Common Raven (larger, more wedge-shaped tail feathers, different sheen), Fish Crow (nearly identical, requires size/auditory comparison), or Boat-tailed Grackle (smaller, different iridescence).
Interesting Facts
Crows are capable of recognizing individual human faces and can communicate specific threats to other members of their flock. They are also known to use tools to extract food.
Condition Notes
Good condition; the vane is mostly intact though there is minor separation of barbs near the mid-section, likely due to natural wear or impact during the molt process.
