A crow is one of those birds that people often notice without thinking much about. It may be standing on a roadside, walking across a field, searching through fallen leaves, or calling from the top of a tree. Its black feathers and loud voice make it easy to recognize. But behind this familiar appearance is a bird with remarkable learning abilities, a complicated social life, and an impressive ability to adapt to changing environments.
The word “crow” can refer to several species in the crow family, Corvidae. One of the best-known is the American Crow (Corvus brachyrhynchos), which lives across much of North America. American Crows are found in open woodlands, farmland, beaches, parks, roadsides, towns, and cities. They are especially successful in places where natural habitats have been changed by people because they can make use of many different food sources.

What Does a Crow Look Like?
The American Crow is a fairly large songbird. It usually measures about 40–53 centimeters long, with a wingspan of roughly 85–100 centimeters. Adults are completely black, including the bill and legs. Fresh feathers can have a glossy appearance, while older feathers may look brownish or worn.
Its flight is also distinctive. Instead of frequently gliding like some larger birds, the American Crow usually flies with steady, deliberate wingbeats. Its tail is relatively short and rounded or squared at the end.

What Do Crows Eat?
Crows are omnivores, which gives them a huge advantage when food changes with the seasons. They can eat seeds, grains, nuts, berries, fruit, insects, earthworms, mice, fish, crayfish, young turtles, and other small animals. They also eat eggs and nestlings of other birds. Carrion and human food waste can become part of their diet as well.
This flexible diet helps explain why crows can live in very different environments. A crow searching for food in a forest may behave quite differently from one living around a city, but both can take advantage of whatever food is available.

Crows Are Highly Social
Crows are rarely as solitary as they may appear from a distance. American Crows often live in family groups, with a breeding pair and younger birds helping to raise new chicks. Young birds may remain with their parents for several years and help with the next generation.
During winter, the situation can become much more dramatic. Large numbers of crows may gather at communal sleeping sites. Some winter roosts can contain hundreds of thousands of birds, and some have been estimated to contain as many as two million crows.

How Intelligent Is a Crow?
Crows have earned their reputation for intelligence through the way they solve problems and learn from experience. They can work together, remember useful sources of food, and change their behavior when circumstances change.
Some crows have also been observed using objects as tools. These behaviors are particularly interesting because they show that crows can manipulate objects in ways that help them investigate their surroundings or obtain food.

How Do Crows Raise Their Young?
American Crows usually build their nests high in trees, often near the trunk or on a horizontal branch. Both members of the breeding pair help construct the nest, and younger family members may sometimes help too.
A female typically lays between three and nine eggs. Incubation lasts about 16–18 days, and young birds remain in the nest for roughly 20–40 days. After leaving the nest, young crows may continue living with their family and helping their parents.

More Than Just a Black Bird
Crows can sometimes be noisy or troublesome around garbage containers, farms, and large communal roosts. Yet their ability to survive alongside people is part of what makes them so interesting. They have adapted to roads, buildings, parks, farmland, and cities without losing the social behavior and problem-solving abilities that make them successful birds.
The next time a crow walks across a parking lot or calls from a nearby tree, it is worth looking twice. What seems like an ordinary black bird may be watching its surroundings, remembering where food can be found, communicating with other crows, and making decisions based on what it has learned. That combination of intelligence, cooperation, and adaptability is what makes the crow such a fascinating member of the bird world.
