The Acorn Woodpecker is a common, conspicuous inhabitant of foothill and montane woodlands from northwestern Oregon, California, the American Southwest, and western Mexico through the highlands of Central America to the northern Andes in Colombia. Throughout its range, this species is closely associated with oaks (genus Quercus) and is most commonly found in pine-oak woodlands. It is probably best known for its highly social habits and unique method of storing acorns in specialized trees known as storage trees or granaries, although group living and acorn storage are not characteristic of all populations. This is generally a sedentary species, but at least one population migrates annually and irregular migrations occur elsewhere when local acorn crops fail.
