National Wildlife Federation Songbird Postcard Series 501-11 REDSTART (Setophaga ruticilla) Of all the warblers, the handsome Redstart is perhaps the most colorful and active. He is extremely restless and constantly hopping from branch to branch in a never-ending search for food. The warblers do a tremendous amount of good in the destruction of insects and it almost seems as though the Redstart was anxious to do the most. They especially like the thick shrubbery and low hanging branches and have little or no fear of humanity. So intent are they in their search for food that they will dart with precision and speed at an insect even though a person is standing directly beside the spot. They are found from Canada through the western states to the Carolinas.
