Through the long narrow valley, hidden between two green hills, marched the Band, following the hidden safe path that generations of foxes had made through the very middle of a treacherous marsh. As the road bent in toward Darby Creek, there sounded the watchman's rattle of the first kingfisher they had heard that year; and as they came to the creek itself, a vast blue-gray bird with a long neck and bill flapped up ahead of them. It was so enormous that Alice-Palace was positive that it was a roc; but it turned out to be the great blue heron, the largest bird in Eastern America. From the marshy fields swept great flocks of red-winged blackbirds, each one showing a yellow-bordered, crimson epaulet, proof positive that Mrs. Blackbird was still in the South. Mrs. Robin had come back the week before, which accounted for the joy-songs which sounded from every tree-top. Until she comes, the robin's song is faint and thin and infrequent. Beyond the creek they heard the "Quick, quick, quick," of the flicker calling to spring, and before long they came to the tree where he had hollowed his hole. A most intelligent flicker he was, too, for his shaft was sunk directly under a sign which read "No Shooting Here." From behind them as they marched, tolled the low sweet bell-notes of the mourning dove--"Ah--coo, coo, coo." The Captain tried to imitate the sound, and the harassed bird stood it as long as he could, but finally flew away with whistling wings. Then the Captain told the Band of a brave mother-dove whose nest he once found on the last day of March. It was only a flat platform of dry sticks in a spruce tree, and held two pearly-white eggs. The day after he found it, there came a sudden snowstorm, and when he saw the nest again, it was covered with snow--but there was the mother-bird still brooding her dear-loved eggs, with her head just showing above the drifted whiteness. [Illustration: MR. FLICKER AT HOME] Beside the ruins of a spring-house, a gray bird with a tilting tail said, "Phoe, bee-bee, bee." It was the little phoebe, so glad to be back that he stuttered when he called his name. Thereafter the Captain was moved to relate another anecdote. It seemed a friend of his had stopped a pair of robins from nesting over a hammock hung under an apple tree, by nailing a stuffed cat right beside their bough. Whereupon the two robins, when they came the next morning, fled with loud chirps of dismay. When two phoebes started to build on his porch, he tried the same plan. He was called out of town the next day, and when he came back a week later he found that the phoebes had deserted their old nest. They had however built a new one--on top of the cat's head.
