1 Overview
The American Crow is one of the most familiar and intelligent birds in North America. With its glossy black plumage and distinctive caw, it is a common sight in backyards, parks, and woodlands across the continent. These birds are members of the corvid family, a group known for its problem-solving abilities and complex social behaviors. Crows are adaptable and curious, often seen investigating new objects or playing with sticks and other items. Their presence in a backyard can be a source of endless entertainment as they interact with each other and with other species.
American Crows are year-round residents in many areas, though some northern populations may migrate short distances in winter. They are highly social, often gathering in large communal roosts during the non-breeding season. These roosts can contain hundreds or even thousands of birds, creating spectacular aerial displays at dawn and dusk. In the backyard, crows are typically seen in small family groups or pairs, especially during the breeding season. They are wary of humans but can become accustomed to regular feeders, particularly if offered their favorite foods.
Despite their abundance, American Crows face challenges from habitat loss, disease, and persecution. Understanding their behavior and needs can help backyard birdwatchers appreciate these clever birds while minimizing conflicts. By providing appropriate food and maintaining a clean feeding station, you can attract crows without encouraging them to become nuisances. Remember that crows are protected under the Migratory Bird Treaty Act, so it is illegal to harm them or disturb their nests without a permit. Enjoy them from a respectful distance and let their antics brighten your day.
2 How to identify it
The American Crow is a large, entirely black bird with a stout bill and broad wings. Adults measure between 16 and 21 inches in length, with a wingspan of about 3 feet. The plumage is uniformly black, but in good light, you may notice a glossy sheen that can appear purplish or greenish. The bill is thick and slightly curved, and the legs and feet are also black. During the summer, crows undergo a complete molt, and their feathers may look ragged and brownish until the new feathers grow in. Juveniles have duller, more brownish-black plumage and pinkish gaps at the corners of the mouth.
In flight, crows have a distinctive, steady wingbeat that is slower than that of smaller birds. They often fly in straight lines, but during displays or when chasing predators, they may perform acrobatic maneuvers. The tail is rounded and fan-shaped when spread. Compared to the similar Common Raven, crows are smaller, with a thinner bill and a more rounded tail. Ravens also have a wedge-shaped tail and a deeper, croaking call. Fish Crows are very similar to American Crows but are slightly smaller and have a more nasal, higher-pitched call. Blue Jays are also corvids but are brightly colored with blue, white, and black plumage, making them easy to distinguish.
Behaviorally, crows are often seen in groups, especially outside the breeding season. They are bold and inquisitive, frequently mobbing hawks and owls. Their calls include the familiar caw, as well as a variety of rattles, clicks, and bell-like notes. Learning these vocalizations can help you identify crows even when they are hidden in foliage. In the backyard, look for crows perched on tall trees or utility poles, surveying the area for food. They may also visit ground feeders or birdbaths, especially if peanuts or corn are available.
3 Where and when to see it
American Crows are widely distributed across North America, from Canada to Mexico. They inhabit a variety of open and semi-open landscapes, including open woods, fields, suburbs, and urban areas. They are absent only from the driest deserts and the highest mountains. In suburban settings, crows are often seen on lawns, in parks, and along roadsides, where they forage for insects and scavenge for food. They are adaptable and can thrive in close proximity to humans, as long as they are not persecuted.
Crows are year-round residents in most of their range, but northern populations may move south in winter, sometimes forming large migratory flocks. In some areas, crows are partially migratory, with some individuals staying put while others move. During winter, communal roosts can be found in wooded areas or urban parks, where hundreds of crows gather at dusk. These roosts are often noisy and can be a spectacle to observe. In spring and summer, breeding pairs disperse and become more territorial, defending a small area around their nest.
The best time to see crows in your backyard is early morning or late afternoon, when they are most active. They are diurnal and may visit feeders throughout the day, but they are often most vocal at dawn. If you want to attract crows, offer food consistently and be patient; they are wary and may take time to trust a new feeding station. During the breeding season, you may see crows carrying food to their nests or chasing away potential predators. In fall and winter, watch for family groups moving together and listen for their varied calls. Keeping a pair of binoculars handy will help you observe their behavior without disturbing them.
4 What it eats (and what to offer)
The American Crow is an omnivore with a highly varied diet. It eats insects, carrion, seeds, nuts, fruits, small animals, eggs, and even garbage. In the wild, crows forage on the ground, in trees, and sometimes in shallow water. They are opportunistic and will take advantage of whatever food is available, including human food scraps. At feeders, crows are particularly fond of peanuts, both in the shell and shelled, as well as cracked corn. They also enjoy suet, kitchen scraps, and pet food, but these should be offered sparingly to avoid attracting rodents or other unwanted guests.
If you want to offer food to crows, choose a platform feeder or simply scatter food on a flat surface, such as a tray or a clean section of ground. Avoid offering bread, which has little nutritional value, and never offer spoiled or moldy food. Peanuts and cracked corn are excellent choices because they are nutritious and resemble natural foods. You can also offer unsalted, unflavored nuts, such as walnuts or almonds, but be sure they are not roasted or salted. Crows are large birds and may dominate smaller feeders, so you might want to provide food in a separate area to avoid scaring away smaller birds.
It is important to keep feeders clean to prevent the spread of disease. Clean your feeder regularly with a mild bleach solution and rinse thoroughly. Discard any leftover food that has become wet or moldy. Also, be mindful that feeding crows can attract other animals, such as raccoons or rats, so avoid leaving food out overnight. If you have pets, keep their food indoors. Remember that crows are wild birds and should not be fed human junk food or processed meats. A diet of natural foods will keep them healthy and encourage them to visit your yard without becoming dependent on unnatural foods.
5 Nesting and behavior
American Crows typically nest in tall trees, often in a crotch or on a horizontal branch, well away from the trunk. The nest is a bulky bowl of sticks, twigs, and bark, lined with softer materials such as grass, moss, and feathers. Both members of a pair help build the nest, which can take up to two weeks to complete. The female lays 3 to 6 eggs, which she incubates for about 18 days. During this time, the male brings her food. After the eggs hatch, both parents feed the chicks, which fledge at around 35 days old. Young crows may stay with their parents for several years, helping to raise subsequent broods.
Crows are highly social and intelligent. They engage in complex behaviors such as play, tool use, and cooperative mobbing of predators. They have been observed dropping sticks and other objects to test them, and they can learn to recognize individual human faces. In the backyard, you may see crows caching food for later, hiding it in grass or under leaves. They are also known to follow other birds to food sources and to steal food from other animals. Their social structure includes family groups that defend territories and help each other. During the non-breeding season, they gather in large roosts, sometimes with thousands of birds, where they engage in social interactions and exchange information.
If you have crows nesting near your home, observe from a distance and avoid disturbing the nest. Crows are protective parents and may dive-bomb perceived threats, including humans and pets. Keep your distance and do not attempt to handle the birds or their young. If a young crow falls from the nest, it is often best to leave it alone unless it is in immediate danger; the parents are likely nearby and will continue to care for it. Remember that crows are protected by law, and it is illegal to harm them or their nests. Enjoy their fascinating behavior from afar and let them raise their families in peace.
6 Attracting this bird
Attracting American Crows to your backyard can be a rewarding experience, but it requires some planning and ethical considerations. First, provide a reliable food source. Offer peanuts, cracked corn, or unsalted nuts on a platform feeder or on a clean, flat surface. Crows are wary, so place the feeder in an open area where they can see potential dangers. Be consistent with feeding times; crows will learn your schedule and may visit regularly. However, avoid overfeeding, as this can lead to dependency and attract unwanted animals. Offer food in moderation, especially during the breeding season when natural food is abundant.
Second, provide water. A birdbath or shallow dish of clean water will attract crows, especially in hot weather. Change the water daily to prevent mosquito breeding and disease. If you have a large yard, consider leaving a brush pile or a dead tree snag for perching and nesting. Crows use tall trees for nesting and roosting, so if you have mature trees, you are already providing habitat. Avoid using pesticides and herbicides, as these can poison crows and reduce their natural food supply. Instead, let your lawn grow a little wild and encourage insects, which are an important part of their diet.
Third, be a responsible host. Keep your feeders clean and disinfect them regularly. Do not feed crows human junk food, bread, or spoiled food. If you have pets, feed them indoors. Crows can become aggressive when defending their nests, so if you have a nest nearby, keep your distance and warn visitors. Also, be aware that crows may mob hawks and owls, which can be stressful for those birds. If you notice a lot of mobbing, consider temporarily removing food to reduce conflict. Finally, enjoy the crows from a respectful distance. Do not try to tame them or handle them. Observe their behavior, listen to their calls, and appreciate their intelligence. By following these tips, you can attract crows while maintaining a healthy and ethical backyard habitat.
7 Frequently asked questions
Q: Are American Crows aggressive toward other birds? A: Crows can be aggressive, especially during the breeding season when they defend their nests. They may chase away other birds, including hawks and owls, but they generally coexist with smaller birds at feeders. If you notice excessive aggression, you can provide separate feeding areas to reduce conflict.
Q: Do crows eat other birds' eggs or chicks? A: Yes, crows are opportunistic omnivores and will eat eggs and nestlings of other birds. This is a natural behavior and part of their role in the ecosystem. However, they are not a major threat to healthy bird populations. If you have nesting songbirds, you can protect them by placing nest boxes with predator guards and keeping crows away from nest areas.
Q: How can I tell a crow from a raven? A: Crows are smaller (16-21 inches) with a rounded tail and a higher-pitched caw. Ravens are larger (about 24 inches) with a wedge-shaped tail and a deep, croaking call. Ravens also have a heavier bill and shaggy throat feathers. If you see a large black bird soaring, it is more likely a raven, as crows rarely soar.
Q: Are crows protected by law? A: Yes, American Crows are protected under the Migratory Bird Treaty Act in the United States, which makes it illegal to harm them, their nests, or their eggs without a permit. In Canada, they are protected under the Migratory Birds Convention Act. Always observe them from a distance and never disturb their nests.
