Blue Tit Behaviour
Blue and Great Tits form mixed winter flocks, and the former are perhaps the better gymnasts on the slender twigs. A Blue Tit will often ascend a trunk in short jerky hops, imitating a Treecreeper. As a rule the bird roosts in ivy or evergreens, but in hard weather will shelter in a hole. Blue tits are very agile and can hang from almost anywhere.
