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. While commonly referred to as "tits" throughout much of the English-speaking world, these birds are called either "chickadees" (onomatopoeic, derived from their distinctive "chick-a dee dee dee" alarm call) or "titmice" in North America. The name titmouse is recorded from the 14th century, composed of the Old English name for the bird, mase (Proto-Germanic *maison, German Meise), and tit, denoting something small. The former spelling, "titmose", was influenced by mouse in the 16th century. All species in this group are relatively small in size, and typically quite vocal. Utah has 9 species in this group.
