NAM Verbeek. 1966 this supplies more evidence that the season is late. The females while Pitelka shot yesterday showed only early stages of brood- pitch development and I believe only one out of 6 had laid egg. On the W. shore of Elson hagoon I found a nest with one egg in it. Of the three birds Pitelka shot there, two had oviphased follicles, and One had laid an egg, the other had a large egg, lacking the final calcareous shell in the oviduct. 11 June Found a nest with 3 eggs in it W of Honey Bucket hagoon. The nest I found on 9 June, partially lined had no eggs yet. Along the N. shore of Ukpik though I flashed a female of her nest of 4 eggs. The fluttered low than the grass for some 20 m. 12 June Saw a male picking up bits of grass while he walked very energetically and in a "frustrated" manner with his tail spread and pressed down and his wings held partly open away from his body. After walking about one to 1½ meters he flew up about 10 meters high and uttered his flight song, causing his pieces of straw to fall to the ground. After a while he repeated this performance, again taking the straws with him into the air and dropping them. The male was alone when he displayed as noted above. 13 June The nest which appeared completed on June 9, contained 3 eggs. 14 June Found three more nests today; all in the drum area. One with 6, 1 ad 4 eggs. The one with 6 eggs is nest #5 16 June Found one nest with 4 eggs. The nest was in a collapsed lemming tunnel and thus had a roof over it. A second nest with 4 eggs
