Gilmoe Red Backed Sandpiper 1931 Sevonga, St. Lawrence Is., Bering Sea. July 12 These sandpipers were very common everywhere over the damp tundras. They utter a peculiar trill, & have the peculiar mannerism of after stretching the one wing vertically above them, when on the ground. Easily confused with The Pribilof Sandpiper, which has, however, the black higher on the breast & neck & no clear cut line between the black & white. Sigara Pt. Hope Alaska Aug 9 Saw half a dozen flocks of 10-20 birds feeding on the tundra around the village. They did not seem to be working in any direction, so I presume they have started their Southward migration. The plumage is as usual save the red on the back is less distinct. Aug 19. These birds are still quite numerous on the tundra & along the shallow ponds. Spring and autumn plumages about half & half. I saw some large flocks of 20 or more feeding on the tundra today.
