May, 1917 TIlE HOME LIFE OF THE BAIRD SANDPIPER 83 bank. In this case the bird fluttered off, simulating a broken wing and uttering cries of distress. We were some twenty-five yards distant when he finshed, and had considerable difficulty in finding the nest. It contained the usual four eggs, so badly incubated that there seemed little hope of saving them, and in every re- spect was typical of the species. The photo (fig. 29) was taken about nine o'clock in the evening. Unfortunately the slanting rays of the sun glinted from the upper surface of the eggs, obscuring the markings, which were unusually bold in this set. Both female and male came about and inspected the camera, while we hid behind a snowbank trying to keep warm by fighting mosquitos. It was over half an hour before the male returned to the nest, and then he insisted upon fac- ing the camera, which is a trait typical of all sandpipers that I have tried to pho- tograph on their nests (fig. ?0). We did not secure any Baird Sandpipers in natal down, as apparently we Fig. 30. SA3fE NEST AS IS SHOWN IN FI6. 29; NEAR GRIFFIN POINT, ARCTIC ALASKA, JULY 11, 1914.

Dr. Anderson, however, took do?my young at Colligon Point on July 11. In the report of the Mcllhenny Expedition to Point Barrow, Stone states: "Ten young in the down were taken July 16, 18 and 27; they are darker than young Dunli?, with the brox? tints darker and not ? rufous, while the light mottlings are whiter and le? tinged with buff. Two others taken Au?st 1 are intermediate between the down and first winter plumage" (Proc. Acad. Nat. Sci. Phila., 1900, p. 26). A young Baird Sandpiper taken at Herschel Island, Yukon, July 30, has the natal down still plainly visible on the back and top of the head (fig. 31); the whitish tips of the feathem on the back are nmch in evidence.
