tyrannus: significado e definições

The name-giving genus of Tyrannidæ, formerly loosely extended to embrace most of the larger species then known (so named from their irritable or irascible disposition and their tendency to tyrannize over other birds), now restricted to a few large stout flycatchers like the common king-bird or bee-martin of the United States, T. tyrannus, T. pipiri, T. intrepidus, or T. carolinensis.
