As we advance into the wood, if it be near mid-day, or before the decline of the sun, the notes of two small birds will be sure to attract our attention. These notes are very similar, and as slender and piercing as the chirp of a grasshopper, being distinguished from the latter only by a different and more pleasing modulation. The birds to which I refer are the Red Start (_Muscicapa ruticilla_) and the Speckled Creeper (_Sylvia varia_). The first is the more rarely seen of the two, being a bird of the deep forest, and shunning observation by hiding himself in the most obscure parts of the wood. In general appearance, and in the color of his plumage, he bears a resemblance to the Ground-Robin, though not more than half his size. He lives entirely on insects, catching them while they are flying in the air. His song is similar to that of the Summer Yellow-Bird, so common in our gardens among the fruit-trees, but it is more shrill and feeble. The Creeper's song does not differ from it more than the songs of different individuals of the same species may differ. This bird may be seen creeping like a Woodpecker around the branches of trees, feeding upon the grubs and insects that are lodged upon the bark. He often leaves the forest, and may be seen busily searching the trees in the orchard and garden. The restless activity of the birds of this species affords a proof of the countless myriads of insects that must be destroyed by them in the course of one season,--insects which, if not kept in check by these and other small birds, would multiply to such an extreme as to render the earth uninhabitable by man. While listening with close attention to the slender notes of either of the last-named birds, often hardly audible amidst the din of grasshoppers, the rustling of leaves, and the sighing of winds among the tall oaken boughs, suddenly the wood resounds with a loud, shrill song, like the sharpest notes of the Canary. The bird that startles one with this vociferous note is the Oven-Bird, (_Turdus aurocapillus_), or Golden-Crowned Thrush. It is the smallest of the Thrushes, is confined exclusively to the wood, and when singing is particularly partial to noon-day. There is no melody in his song. He begins rather low, increasing in loudness as he proceeds, until the last notes are so loud as to seem almost in our immediate presence. He might be supposed to utter His words, _I see_, _I see_, _I see_, etc.,--emphasizing the first word, and repeating the words six or eight times, louder and louder with each repetition. No other bird equals this little Thrush in the emphasis with which he delivers his brief communication. His notes are associated with summer noon-days in the deep woods, and, when bursting upon the ear in the silence of noon, they disperse all melancholy thoughts, and inspire one with a vivid consciousness of life.
