of its time clinging to tree trunks and branches, often trying to hide on the side away from the observer. Its presence is often announced by its loud call or by its distinctive spring 'drumming' display. The male has a distinctive red patch on the nape and young birds have a red crown. Both sexes have a red patch on the undertail. It lives in woodlands, especially with mature broad-leaved trees, although mature conifers will support them. Also in parks and large gardens. It feeds on larvas and small insects found on the tree trunks.
