This ball of feathers weighing less than 50 g is a typical bird inhabiting alpine environments.
Present in the mountains all year round, it can be observed between 1800 and 4000 m altitude. It nests in rock holes and descends to more favourable altitudes in winter.
Its diet is adapted to the season: it feeds mainly on insects in summer, seeds in autumn and takes advantage of the food available around cabins in winter!
They are not shy, and it is not unusual for them to approach humans.
