One would every now and then stretch both wings right over its back, and afterwards commence a grotesque sort of dance, hopping alternately on each leg; another would inflate its gular pouch and run about, crouching down to the ground, or would fly up to about a hundred feet in the air, then inflate its pouch and descend slowly and obliquely to the ground on extended wings. All these performances were accompanied by a strange hollow sound, not very loud when near, but audible at some distance, even as far as 500 yards. These notes are very difficult to locate, and vary according to the distance. When near they are tremulous booming sounds something like the notes of a frog, and end in clear sounds like those caused by the bursting of water bubbles in a copper vessel. _Nesting._--Mr. Murdoch (1885) says: The nest is always built in the grass, with a decided preference for high and dry localities like the banks of gulleys and streams. It was sometimes placed at the edge of a small pool, but always in grass and in a dry place, never in the black clay and moss, like the plover and buff-breasted sandpipers, or in the marsh, like the phalaropes. The nest was like that of the other waders, a depression in the ground lined with a little dry grass. A set in my collection, taken by F. S. Hersey, near St. Michael, Alaska, was in a slight hollow on the open tundra with no concealment. And a set in the Herbert Massey collection, taken near Point Barrow by E. A. McIlhenny, came from "a slight hollow lined with dry grass, in the dry, gray moss of the tundra." Herbert W. Brandt in his manuscript notes says:
