It can also reduce the size of the entrance to its nesting cavity by sealing it with mud, thus keeping larger and unwelcome competitors for nesting sites such as the Common Starling at bay. Unlike treecreepers and woodpeckers, the Eurasian Nuthatch does not use its tail for climbing. It holds on merely by its strong feet and toes."}
