|Often shortened to: flycatcher any passerine bird of the American family Tyrannidae|
any of about 367 species of aggressive, insect-eating New World birds of the family Tyrannidae (order Passeriformes). About one-third of the species are not flycatcher-like in habit and bear names derived from their habitats (e.g., bush tyrant, marsh tyrant) or from their similarity to the songbird groups (tit-tyrant, shrike-tyrant). A few are named for their bill shape (spade bill, flat bill, bent bill). Many have common names not suggestive of their appearance (e.g., phoebe, pewee, kingbird).
