For example, in flycatchers of the family Tyrannidae, in which some member species are more adapted for hawking insects on the wing and others for gleaning, the gleaners have bills that resemble those of tits and warblers, unlike their larger-billed relatives.
To illustrate, certain flycatcher species in the Tyrannidae family have evolved to specialize in catching insects while in flight, whereas others are better equipped for plucking them from surfaces. The former tend to possess bills resembling those of finches and sparrows, differing from their larger-billed kin.
