The willow tit (Poecile montanus)
These birds are quite common, and live everywhere. In coniferous and mixed forests, in mountain forests. In general, wherever there are forests and old rotting and dead trees in which they nest.
This tit is very noisy, and you can find out about its location by its frequent nasal calls. She is quite sociable and friendly to other bird species, a frequent participant in mixed bird flocks.
When she is not hungry, she makes reserves for the future. Thanks to very tenacious claws, she clings to the bark of a tree and hide food in the holes.
In cold times, in order to keep warm, she is very fluffy, for which, in some countries, she was called - puff.
