The willow tit (Poecile montanus)
Often these birds can be found together. In autumn, birds such as the great tit, coal tit, long-tailed tit, , nuthatch, treecreeper, different types of woodpeckers, chiffchaff (before the cold weather in October, then she migrates), join together in a mixed flock, and together roam in the woods in search of food.
The Eurasian nuthatch or wood nuthatch (Sitta europaea)
This helps them survive and are not afraid of birds of prey. I have a theory that it is in this flock that each bird enjoys various benefits.
For example, as I understand it, woodpeckers have poorly developed attentiveness, and they can easily become victims of predator. And therefore, he keeps together with small birds, which easily notice the danger and warn the others about it.
And small birds, in turn, examine the wood chips remaining after woodpeckers, where they find various insects and their larvae.
