A faint "screep, screep," like "the noise made by striking two pebbles together," Audubon says, is often the only indication of the blackpoll's presence; but surely that tireless bird-student had heard its more characteristic notes, which, rapidly uttered, increasing in the middle of the strain and diminishing toward the end, suggest the shrill, wiry burn of some midsummer insect. After the opera-glass has searched him out we find him by no means an inconspicuous bird. A dainty little fellow, with a glossy black cap pulled over his eyes, he is almost hidden by the dense foliage on the trees by the time he returns to us at the very end of spring. Giraud says that he is the very last of his tribe to come north, though the bay-breasted warbler has usually been thought the bird to wind up the spring procession.
