That same day, on the edge of the thick woods near the schoolhouse, I found swinging from maple saplings, four and five feet from the ground, the beautiful little woven baskets, thatched on the outside with white birch-bark and lined within with pine-needles, of the red-eyed vireo, with the black line through and the white line above her red eye. In the vast, bare hardhack pasture on the slope of Pond Hill, I watched a field sparrow fly down under a hardhack bush with a bug in its beak. Hurrying there, I found on the ground, concealed by the bush, her little nest of woven grass, with four little field sparrows inside, whose gaping beaks kept both father and mother field sparrow busy all day to fill them. As the parent birds flitted around me, I could see plainly the pink beak which distinguishes the field sparrow from all others of its family. Beside the brook, among the cat-tails on the ground, I found the rough nest of the red-winged blackbird, with its four eggs scrawled with strange black hieroglyphics. The fourth day was another treasure-trove day. Just at dawn, in a dew-drenched thicket of spirea, I found three nests not six feet apart. In one, root-lined and thatched with strips of grape-vine bark, glowed the four deep blue eggs of the cat bird. The next nest, singularly deep and made of dried grass, was owned by a black-blue indigo bunting who, in spite of his intense coloring, seemed content with three washed-out white eggs and a light-brown wife. On the last nest the bird was brooding, and showed the golden-crowned head and the chestnut band along the side which has given its name to the chestnut-sided warbler. The nest, a humble affair of grass and hair, sheltered four wonderful eggs, pink-white, spotted at the largest end with flecks of chocolate and lilac and umber. Back of the thickets tottered an old, old house. For fifty years it had been leased to the wild-folk. As I looked at it, one of them flitted out of the cellar-way, a gray bird whose name-note was phoebe. Just within the doorway, on an oak beam, I found her new-finished nest of fresh, bright, green moss.
