It is a small forest passerine that often lives in the company of its brethren, such as the Black-capped Chickadee or the Willow Tit, as they share the same habitats.
Its presence is linked to that of old trees, either dead wood or ageing trees, also known as "senescent wood". It is particularly fond of coniferous forests (spruce, pine and fir).
It is a lively little ball of energy, constantly on the move and recognisable by its crested tail. It feeds on small insects, larvae and spiders, as well as conifer seeds.
