When to seeJanuary to December
AboutA slim, tit-sized bird, the treecreeper has a long, pointed tail and a fine, downwards-curved bill. Treecreepers climb up trees in a spiral around the trunk, feeding on insects and spiders that they find in crevices in the bark. They have long, curved toes that help them cling to the bark, and really stiff tail feathers that they can push against the tree for extra support.
They are residents in the UK, leaving their breeding territories in autumn, but usually going no further than a few kilometres. In autumn and winter, treecreepers often join flocks of tits, roaming woodlands and parks for food.
