Tits
The tits, chickadees, and titmice constitute the Paridae, a large family of small passerine birds which occur mainly in the Northern Hemisphere and Africa. Most were formerly classified in the genus Parus.
Members of this family are commonly referred to as "tits" throughout much of the English speaking world, but North American species are called either "chickadees" or "titmice". The name titmouse is recorded from the 14th century, composed of the Old English name for the bird, mase, and tit, denoting something small.
