Tits, chickadees, and titmice belong to the Paridae family, which consists of small passerine birds mainly found in the Northern Hemisphere and Africa. These stocky birds, typically 10 to 22 cm (3.9 to 8.7 inches) in length, have short, stout bills and some possess crests. They are adaptable and have a diet of seeds and insects. Many species are comfortable living near humans, frequently visiting bird feeders for nuts and seeds.
