The Family Certhiidae comprises of 11 species of small arboreal birds, commonly known as Treecreepers. Other synonyms for the family name include "tree creepers," "tree-creepers," or "creepers." They are found in temperate regions of the Northern Hemisphere, and their populations are spread across Europe, Asia, and North America. These birds are known for their unique behavior of climbing tree trunks or other vertical surfaces in search of insects, which they feed upon. Treecreepers have brown plumage with streaks of white and are often overlooked due to their cryptic coloration. They belong to the same family as the nuthatches and are often confused with them.
