Yellow Warblers are a frequent target of Brown-Headed Cowbirds who lay their eggs in the warbler's nest so that their young can be raised by the warblers. The Yellow Warblers fight this forced adoption system by covering the cowbird eggs with another layer of nest and then lay a fresh batch of their own eggs.
These birds are not shy. If they are around you will most likely hear them and see them which is a treat much like their song.....sweet, sweet, sweet, sweeter than sweet!
