It grows to about 12-13 centimetres (5 inches) tall. 

It is common and native to Europe and Asia, from Ireland to Japan. It is not found in the northern or southern parts of Europe and Asia. It is residential, which means that it is non-migratory. 

It prefers parks, gardens, and woodlands, especially woods with coniferous forests. It is a tree-dwelling bird. 

The Eurasian Treecreeper is insectivorous, eating insects from tree trunks. It also eats spiders. Its predators include woodpeckers and squirrels. 

The Eurasian Treecreeper nests in tree crevices or behind flakes of bark. The female lays 5-6 eggs in a moss-lined or feather-lined nest made of twigs, grass, bark, and pine needles. She sits on the eggs, which hatch after 13-17 days. 

The chicks are born altricial—featherless and blind. Both parents feed the chicks. It takes about 17 days for the chicks to grow their flight feathers.
