Tits (Paridae)
Species
Tits are tiny to small-sized mainly arboreal birds with tubby bodies, short wings and tiny probing bills. Many species have black caps or crests. They are mostly gregarious outside the breeding season and often form large winter flocks comprising several species. Although they are predominantly insectivorous, they also take seeds and nuts. Normally they nest in holes in trees.
 
There are 65 species worldwide, in the Holarctic and Ethiopian regions. Nine species breed in Europe.
