Ravens have a wide distribution across the Northern Hemisphere, found in North America, Europe, Asia, and parts of North Africa. They favor a variety of habitats, including forests, tundra, mountains, deserts, and even some urban areas.
The size of their population can vary depending on factors such as habitat availability, food resources, and human activity. However, in general, ravens are considered to be common birds in their range, and their populations are stable or even increasing in some regions.
