Corvus corax, commonly known as the common raven, has a vast geographical distribution. It is native to the Northern Hemisphere and can be found across much of North America, Europe, Asia, and North Africa. The species is notably adaptable and occupies a range of environments across these regions.

Common ravens inhabit diverse environmental conditions. They are found in forests, mountains, coastal regions, deserts, and tundra environments. Ravens are highly adaptable and can thrive in both rural and urban settings, from sea level to high mountainous areas. Their presence in such varied climates demonstrates their formidable adaptability to different temperatures, precipitation levels, and altitudes.

Corvus corax fills the ecological niche of a scavenger and predator, playing significant roles in food webs. As omnivores, they consume a wide range of food, including carrion, insects, small animals, grains, and human refuse. Their intelligence and problem-solving skills aid in accessing diverse food sources. Ravens are also known for their interaction with other species, sometimes following predators to scavenge leftovers from kills.
