Janiich 1953 Nyctea scandiaca June 26 Point Barrow, Alaska eaten. We removed all the lemmings except these parts, and weighed and determined sex of each. Then marking 21 by breaking a hind leg of each one we replaced these at the nest edge. Young owls were weighed and returned to the nest. Adults did not fly overhead. June 27 One on beach at plot L.E. This morning I visited nest #1 near Vath's station and confirmed what I had noticed several days ago, that the nest contains one chick. The other eggs have vanished but one half shell of a hatched egg is near the base of the mound. June 28 Visited nest #2 with Pitelka and Thompson. Five warm eggs in nest, one cold one about a foot away, as if just hatched there on a sudden leaving. I left nest as we approached. Both adults in the vicinity, perched on mounds but not interfering with our examination of the nest. July 4 Two in drum area in late morning. July 5 One on beach at plot L.E. July 7 One at Nuvuk. I gathered a 10-lb. bag full of pellets from mounds and ruins there. July 8 At Nest #2 eggs intact, none hatched, 9 sitting. July 10 White one, evidently 5 adult, on beach at plot L.E. July 12 One at Nuvuk, evidently a 57. July 13 Nest #2 abandoned, eggs cold, one of them with a small puncture; birds not in the area.
