The pygmy nuthatch is the smallest bird among all nuthatches. It lives in pine forests in the west of North America and skillfully climbs tree trunks.
The pygmy nuthatch differs from other nuthatches by its very small size and strong attachment to pine forests. It is beneficial for nature because it destroys harmful insects that damage trees.
