Plump and bench, it has pink and black speckles and a very long and graduated tail.


Sedentary-breeder, regular migrant and winter visitor.
It nests in March-May and lays 7 to 12 eggs. Normally one brood per year, rarely two. He lives no more than 8 years. It moves with short flights, from bush to bush, inspecting every leaf, every piece of bark, looking for insects with which it feeds. In winter, to protect from the cold, it swells the plumage and gathers in groups of 5 to a maximum of 18 specimens. These winter flocks are territorial and actively defend a common area of ​​about twenty hectares. Inside there are the dormitories, places to drink and various feeding areas, patrolled daily along fixed routes. With the arrival of spring, the group gradually dissolves giving rise to various couples who settle in different parts of the common area. Each, often helped by other specimens, is dedicated to the construction of an elaborate nest hidden among the bushes or leaning against the trunk of a tree: a large ball consisting of moss and lichen held together by spider webs, used as cement. Inside, a thick feather padding ensures the necessary warmth and protection. In this ball the reproductive cycle is completed until 5-7 children are hired. The bankruptcies however are very numerous, due to predators or adverse environmental conditions.
