Large and pugnacious, this common tit is found in a wide range of wooded habitats, from dense hill forests to manicured city parks. Found throughout much of East Asia, this species is closely-related to the more brightly-colored Great Tit, from which it was split as a distinct species. Adult has a flashy white cheek on a black head, a black stripe on a white belly, and gray wings with a hint of green near the shoulder. Juveniles are duller, replacing the adult’s black with gray. Very vocal; song is a bright “tzi-hei tzi-hei!”; also gives loud chips, seeps, and harsh “tzi-tzi-tzshhhhhh.”
