Crows are a common and highly visible component of Missouri’s avian population. These intelligent birds are found throughout the entire state, establishing themselves as year-round residents in nearly every environment. The American Crow is the species most frequently encountered, demonstrating an exceptional ability to adapt to both rural and densely populated human landscapes. Their success is a result of their flexible diet and social structure, allowing them to thrive wherever resources are available.
Identifying the Missouri Crow Species
The primary crow species inhabiting Missouri is the American Crow, a large bird characterized by its entirely black plumage, including its legs, feet, and heavy bill. In direct sunlight, the feathers can exhibit a subtle purplish sheen. American Crows measure between 17 and 21 inches long and are distinguished from the much larger Common Raven by their slightly rounded tail shape in flight.
The most recognizable feature of the American Crow is its loud, harsh, and familiar “caw, caw” vocalization. A second species, the Fish Crow, is also present, but its range is largely restricted to areas along major rivers, such as the Mississippi and Missouri. Fish Crows are nearly identical in appearance but slightly smaller. The best method for distinguishing them is their distinctly different, more nasal, two-note call that sounds like “AAH—aah”.
Statewide Distribution and Seasonal Presence
American Crows are common permanent residents across the entirety of Missouri. They adapt to habitats ranging from open agricultural fields and dense woodlots to city parks and suburban neighborhoods. They thrive in areas that offer a combination of open space for foraging and trees for nesting and roosting. This allows them to be an equally familiar sight in rural farmlands and urban centers.
Although the species is a permanent fixture, the local population swells noticeably during the colder months. Northern American Crows migrate south into Missouri for the winter, significantly increasing bird numbers. During this season, they often concentrate in agricultural areas, particularly in river floodplains, where waste grain and other food sources are abundant.
Notable Local Behaviors
A striking behavior observable in Missouri is the formation of large communal winter roosts, which can involve thousands of individual crows gathering nightly in a single wooded area. These groups often choose urban or suburban woodlots for safety and proximity to food sources. They disperse widely each morning to feed and return at dusk. This social behavior highlights their intelligence, allowing them to solve complex problems and even recognize individual human faces.
The American Crow is an omnivore, which is a major factor in its success throughout the state. Their diet is highly diverse, consisting of insects, seeds, fruit, nuts, and carrion, such as roadkill. This flexible feeding strategy, coupled with their intelligence, makes them adept at exploiting resources in human-altered environments.
