Very early in the spring the Red-backed Sandpiper leaves its winter home in the States and countries bordering the Gulf of Mexico and starts on its long journey to the cooler region of the far north. It arrives in Alaska early in May, in full breeding plumage, and the males are soon engaged in prettily wooing the coy females. Mr. Nelson, who had unexcelled opportunities for studying the habits of these interesting sandpipers, well describes their courting habits. He says: “The males may be seen upon quivering wings flying after the female and uttering a musical, trilling note, which falls upon the ear like the mellow tinkle of large water-drops falling rapidly into a partly filled vessel. Imagine the sounds thus produced by the water run together into a steady and rapid trill some five or ten seconds in length, and the note of this Sandpiper is represented. It is not loud, but has a rich, full tone, difficult to describe, but pleasant to hear. As the lover’s suit approaches its end the handsome suitor becomes exalted, and in his moments of excitement he rises fifteen or twenty yards, and hovering on tremulous wings over the object of his passion, pours forth a perfect gush of music, until he glides back to earth exhausted, but ready to repeat the effort a few minutes later. The female coyly retreats before the advance of the male, but after various mishaps each bird finds its partner for the summer and they start off house-hunting in all the ardor of a rising honeymoon.” The Red-backed Sandpiper is not a bird architect and it does not build even a simple home. A slight hollow on a dry knoll, which commands a clear view of some body of water, is the site usually selected. Here the eggs are laid, either upon the dry grass already in the hollow or upon a few bits of leaves, twigs and grass hastily gathered and placed without order. After the appearance of the eggs the male seems to realize the responsibility of family cares, for his merry song ceases and he devotes his share of time to sitting on the nest, protecting the eggs with his warm body. That this is the case is shown by the bare patches that appear on his breast at this season. With such a home as is prepared for their reception, it is not surprising that the little red-backs leave the nest as soon as they are hatched and freely run about. When frightened they readily conceal themselves by sitting on the ground and remaining quiet.
