Woodpeckers are part of the bird family Picidae, which includes piculets, wrynecks, and sapsuckers. They are found worldwide, except in Australia, New Guinea, New Zealand, Madagascar, and polar regions. Most species live in forests, while some adapt to treeless areas, such as rocky hillsides and deserts.
