Dryobates villosus, commonly known as the hairy woodpecker, is native to North America. It is found across a wide geographical range covering parts of the United States, Canada, and parts of Central America, including Mexico.

Hairy woodpeckers are typically found in mature forests and woodlands, particularly those dominated by deciduous or mixed tree species. They prefer areas with standing dead trees or fallen logs, which are crucial for feeding and nesting. They can also inhabit secondary growth forests, urban parks, and suburban areas.

As an insectivorous bird, the hairy woodpecker plays a role in controlling insect populations within its ecosystem. It uses its strong beak to bore into tree bark to extract insects like beetle larvae, ants, and other wood-boring insects. It also consumes some plant material, including seeds and berries, which allows it to adapt to different food availabilities throughout the year.
