At times they Sept. 25. would walk about slowly and sedately like Pectorals, thenrun briskly busily to and fro exactly like "Peeps"! The longer I watched them the stronger became my impression that they were Ereune- tes but still their breasts looked too brown and their size too large. Finally getting them together I shot them both, not without strong reluctance, but to my delight they proved to be really Tringa bairdii, a young δ and an old female. On skinning them I found them to be in good condition but not so fat as Waders usually are at this season. 27
