Pileolated Warbler
685a. Wilsonia pusilla pileolata. 5 inches.
Range.—Western North America, breeding in Oregon, Washington and California to Mexican borders. These little birds, with their deep yellow under parts and breast, and little cap of jet black, are quite common about many of the orchards and gardens when the trees are in full blossom, taking insects that abound at that time. They nest in moist grounds in a slight depression or in low bushes, made of fibers and grass.
