The nest of a Ruff (Philomachus pugnax), containing four eggs, was discovered at Point Lay (69°44′N 163°00′W), on Alaska’s arctic coastal plain, on 21 June 1976. It was a completely canopied cup at the edge of a dry hummock, 30 cm above a very wet, natural drainage. It was placed deep in a clump of sedge and was completely concealed from above and from 300° of the compass at a height of 30 cm above nest level. The four eggs were olive with dark brown splotches, most heavily marked about the large ends, and measured 45.4 x 30.5 mm, 43.5 x 30 mm, 44 x 30.3 mm, and 42.2 x 31 mm.
