Thoreau writes in his journal:
6 A.M.—Is not the chipping sparrow the commonest heard in the village streets in the mornings now, sitting on an elm or apple tree? Was it the black and white warbler that I saw this morning ? It did not stop to creep round the trunks; was very shy. Or was it the myrtle-bird? Might it have been the log-cock woodpecker that I saw yesterday morning? Reptiles must not be omitted, especially frogs; their croaking is the most earthy sound now, a rustling of the scurf of the earth, not to be overlooked in the awakening of the year. It is such an earth-sound . . .
