So plainly expressive of sadness is this peculiar note, that it is difficult to believe that the little being that utters it can be free from sorrow. Certainly he can have no congeniality of feeling with the sprightly Bobolink. Perhaps, with the rest of his species, he represents only the fragment of a superior race, which, according to the metempsychosis, have fallen from their original importance, and this melancholy note is but the partial utterance of sorrow that still lingers in their breasts after the occasion of it is forgotten. Though a shy and retiring bird, the Pewee is known to almost every person, on account of its remarkable note. Like the swallow, he builds his nest under a sheltering roof or rock, and it is often fixed upon a beam or plank under a bridge that crosses a small stream. Near this place he takes his station, on the branch of a tree or the top of a fence, and sits patiently waiting for every moth, chafer, or butterfly that passes along. Fortunately, there are no prejudices existing in the community against this bird that provoke men to destroy him. As he is known to feed entirely on insects, he cannot be suspected of doing mischief on the farm or in the garden, and is considered worthy of protection. I would remark in this place, that the Fly-Catchers and Swallows, and a few other species that enjoy an immunity in our land, would, though multiplied to infinity, perform only those offices which are assigned them by Nature. It is a vain hope that leads one to believe, while he is engaged in exterminating a certain species of small birds, that their places can be supplied and their services performed by other species which are allowed to multiply to excess. The preservation of every species of indigenous birds is the only means that can prevent the over-multiplication of injurious insects. As we return homeward, we soon find ourselves surrounded by the familiar birds that shun the forest and assemble around the habitations of men. Among them the Blue-Bird meets our sight, upon the roofs and fences as well as in the field and orchard. At the risk of introducing him into a company to which he does not strictly belong, I will attempt in this place to describe some of his habits. The Blue-Bird (_Sylvia sialis_) arrives very early in spring, and is detained late in the autumn by his habit of raising two or more broods of young in the season. He is said to bear a strong resemblance to the English Robin-Redbreast, being similar in form and size, each having a red breast and short tail-feathers, with only this manifest difference, that one is olive-colored above where the other is blue. But the Blue-Bird does not equal the Redbreast as a songster. His notes are few, not greatly varied, though melodious and sweetly and plaintively modulated, and never loud. On account of their want of variety, they do not enchain a listener, but they constitute a delightful part in the woodland melodies of morn.
