DEFINITIONS

TYRANNUS
(Tyrannidae; Ϯ Eastern Kingbird T. tyrannus) Based on "Le Tyran.    Tyrannus" of Brisson 1760: "Tandis que la femelle couve, le mâle chasse d'auprès de son nid tous les Oiseaux; même les Faucons & les Aigles." (see tyrannus ●); "NEUVIÈME ORDRE.  Bec échancré.   24. PIE-GRIÈCHE. Lanius.   ...   25.TYRAN. Tyrannus. {Le bec long, droit, et garni de soies à sa base.    26. GOBE-MOUCHE. Muscicapa.   ...   27. MOUCHEROLLE. Muscivora" (de Lacépède 1799); "Tyrannus Lacepède, 1799, Tabl. Méth. Mamm. Ois., p. 5. Type, by tautonymy, Lanius tyrannus Linnaeus." (Traylor in Peters 1979, VIII, 221). The tyrants, pittas, broadbills and their allies form a very distinct group and should, perhaps, be separated from other passerines in a new order Subosciniformes.
Var. Tirannus, Tiranus, Tryannus.
Synon. Despotes, Dioctes, Drymonax, Laphyctes, Melittarchus, Milvulus, Muscivora, Myiocapta, Satellus, Semnarchus, Tolmarchus.
