In the Alleghanies, and from New Jersey and Illinois north-ward, this restless little warbler nests in the bushy borders of woodlands and the undergrowth of the woods, for which he for-sakes our gardens and orchards after a very short visit in May. While hopping over the ground catching ants, of which he seems to be inordinately fond, or flitting actively about the shrubbery after grubs and insects, we may note his coat of many colors—patchwork in which nearly all the warbler colors are curiously combined. With drooped wings that often conceal the bird’s chestnut sides, which are his chief distinguishing mark, and with tail erected like a redstart’s, he hunts incessantly. Here in the garden he is as refreshingly indifferent to your interest in him as later in his breeding haunts he is shy and distrustful. His song is bright and animated, like that of the yellow warbler.
