The American crow (Corvus brachyrhynchos) is native to North America, with a geographical distribution that spans across the entire continent. It can be found from Southern Canada, across the United States, to Northern Mexico. The species is widespread and common throughout these regions.

American crows are highly adaptable birds, thriving in a variety of environmental conditions. They inhabit areas ranging from rural farmlands and forest edges to urban parks and suburban neighborhoods. The species is versatile in terms of climate, living in temperate zones with cold winters and hot summers.

The American crow occupies a generalist ecological niche, which allows it to exploit various food resources and nesting sites. They are omnivorous, feeding on a diet that includes insects, seeds, fruits, carrion, and human food waste. Their adaptability to different environments and flexible diet play a key role in their success across diverse habitats. Unique regional adaptations might be observed, such as slight variations in diet based on locally available food sources.
