116 them. On the sixteenth day after their exclusion from the egg, they took to wing, and ascended the branches of the tree, with surprising ease and firmness. They were fed another day after, on the same tree, and roosted close together in a row on a small twig, the parents just above them. The next morning they flew across the street, and betook themselves to a fine peach-orchard several hundred yards from my lodging. Never had watched the operations of his bees with more intentness than I had employed on this occasion, and I bade them adieu at last with great regret.

The principal food of this species consists of small black caterpillars, which that season infested all the poplars in the street. They searched for them in the manner of the Red-eyed Flycatcher and Blue-eyed Yellow Warbler, moving sidewise along the twigs, like the latter, now and then balancing themselves on the wing opposite their prey, and snapping it in the manner of the Muscicapa Ruticilla, sometimes alighting sidewise on the tree, seldom sallying forth in pursuit of insects more than a few yards, and always preferring to remain among the branches. I never saw either of the old birds disgorge pellets, as I have seen Pewees do.

I observed that they now and then stood in a stiffened attitude, balancing their body from side to side on the joint of the tarsus and toes, as on a hinge, but could not discover the import of this singular action. During the love days of the pair mentioned above, the male would spread its little wings and tail, and strut in short circles round the female, pouring out a low warble so sweet and mellow that I can compare it only to the sounds of a good musical box. The female received these attentions without coyness, and I have often thought that these birds had been attached to each other before that season.

No name could have been imposed upon this species with more propriety than that of the Warbling Flycatcher. The male sings from morning to night, so sweetly, so tenderly, with so much mellowness and softness of tone, and yet with notes so low, that one might think he sings only for his beloved, without the least desire to attract the attention of rivals. In this he differs greatly from most other birds. Even its chiding notes—tsche, tsche, were low and unobtruding. The nestlings uttered a lisping sound, not unlike that of a young mouse. The only time I saw the old birds ruffled, was on discovering a brown lizard ascending their tree. They attacked it courageously, indeed furiously, and although I did not see them strike it, compelled it to leave the place.
