Family: Corvidae (Crows, Jays, and Magpies)
- Shape
- Strongly asymmetrical with a noticeably narrower leading edge (outer vane) than the trailing edge (inner vane); the tip is rounded to slightly blunted.
- Size
- Estimated at 18-22 cm (7-9 inches) in length. This is consistent with the primary feathers of an adult American Crow, which typically range between 15 and 25 cm depending on the wing position.
- Rarity
- Very Common; one of the most widespread and easily recognized birds in North America.

Description
This feather belongs to the American Crow, a large, all-black passerine known for its intelligence. Adult crows have a heavy bill and a wingspan of approximately 3 feet. Their flight is characterized by slow, methodical wingbeats. They are highly social and famous for their 'caw-caw' vocalizations.
Colour & Pattern
Uniformly deep black/charcoal with a subtle structural iridescence that appears violet or blue-green when viewed at a specific angle (visible on the upper left portion). There are no bands or spots.
Barb Structure
Tightly interlocked pennaceous barbs providing a stiff, aerodynamic surface; plumulaceous (downy) barbs are visible at the very base near the calamus.
Texture & Surface
Smooth and glossy on the dorsal surface with a slight oily sheen for weatherproofing; the leading edge is very stiff while the trailing edge is more flexible.
Key Features
Solid black coloration, subtle blue-violet iridescence, strong asymmetry of the vanes, and a robust, dark rachis that becomes pale only at the very base.
Habitat
Highly adaptable; found in open woodlands, agricultural fields, city parks, shorelines, and suburban yards.
Geographic Range
Common throughout most of North America, spanning from southern Canada to northern Mexico; predominantly a year-round resident in most of its range.
Ecological Role
Omnivorous scavenger and predator; they play a vital role in cleaning up carrion and controlling insect populations, though they also impact songbirds by predating nests.
Similar Species
Common Raven (larger, more wedge-shaped tail feathers, thicker rachis), Fish Crow (nearly identical, requires size comparison or vocal ID), and Boat-tailed Grackle (smaller, different iridescence).
Interesting Facts
Crows are among the most intelligent animals on Earth, capable of using tools, recognizing individual human faces, and mourning their dead in social gatherings called 'funerals'.
Condition Notes
Good condition. The vanes are mostly intact with minor 'zipper' separations at the trailing edge. The pale calamus suggests it may have been naturally molted.
