American Crow

The American Crow is a large, highly adaptable corvid found across nearly all of North America south of the Arctic tundra. Its feathers are entirely black with a subtle glossy sheen that can show faint purple or blue iridescence in strong light. Because crows are common in farmland, cities, and woodland edges alike, their feathers are frequently encountered and often need to be distinguished from those of ravens and other blackbirds.

Size and Shape

American Crow flight feathers are substantial, with primaries often 20-25 cm long and a broad, evenly rounded shape; tail feathers are similarly broad and slightly rounded at the tip.

Color and Pattern

• Entirely black with no barring, spotting, or contrasting patches
• A faint glossy sheen, sometimes showing subtle purplish or bluish tones in direct light
• Shafts are black, blending with the vane

Distinguishing from Similar Species

American Crow feathers are smaller and less heavily built than Common Raven feathers, which are notably longer, broader, and often show a more pronounced diamond- or wedge-shaped tail feather profile. Compared to grackles and other blackbirds, crow feathers are considerably larger and lack any greenish or bronze iridescence.

Adult American Crows are uniformly glossy black with no seasonal or sex-based plumage differences. Juveniles look similar but their feathers can appear slightly duller and browner before their first complete molt. Adults undergo a complete molt in summer after breeding, replacing flight feathers in a sequential pattern that keeps the bird capable of flight throughout the process.

American Crows are found nearly throughout the continental United States and southern Canada, occupying farmland, open woodlands, suburban and urban areas, parks, and shorelines. Northern populations may move south in winter, but many populations are resident year-round, especially where food and shelter are reliably available in developed landscapes.

Crows are omnivorous generalists, taking insects, small vertebrates, grain, fruit, and human food waste, and are known for caching food and using simple tools on occasion. They nest in trees, building a bulky stick nest, and often breed cooperatively with young from previous years helping raise new broods. Their calls are a familiar harsh, nasal "caw," and they are highly social, forming large communal winter roosts that can number in the thousands.
