While visiting my friend Mr. John M. Thayer at his country place in Lancaster, Massachusetts about the middle of August, 1910. I was surprised to learn that a dozen or more Kingbirds, which we started from a belt of shrubbery by the roadside, had been feeding there for days on the fruit of the arrow wood ( Viburnum dentatum ). Mr. Thayer had repeatedly watched them eating the small, dull blue berries with great apparent eagerness and relish although they are dry and bitter to the human palate. At length I saw a bird pick one of them from the stem and quickly swallow it. On no other occasion that I remember have I ever observed a Kingbird eating anything save insects.
