 74 THE CONDOR Vol. XVI. l>haleris psittacula. Paroquet Auklet. I several times saw birds that 'I be- lieved to be of this species among the islands in the bay, but was never able to approach within gun shot. Grinnell. (1898, p. 124) records a specimen taken by Fred Frobese near Sitka June 8, 1896, and, according to Finsch (1873, p. 82), a specimen from Sitka is in the Leyden Museum. This record is probably taken from Schlegel. Synthliboramphus antiquus. Ancient Murrelet. Rather common on the more exposed bodies of salt water during my entire stay, and probably occurs throughout the year. Not so plentiful as the next species. On August 2, 1913, I found two broken eggs, apparently of this bird, in a burrow among the grass roots on a steep hillside on St. Lazaria Island. One of the eggs was in a fair state of preservation, but they were apparently at least a year old when found. llrachyramphus marraoratus. Marbled Murrelet. Abundant on salt water throughout the district. The young were raised and on the water at the time of my arrival, and I was unable to secure any information as to the location of the nesting grounds. llrachyramphus brevirostris. Kittlitz Murrelet. An adult bird secured at Biorka Island, July 24, 1912, was the only one noted. Cepphus eohmba. Pigeon Guillemot. Rather plentiful on salt water. Nest- ing in considerable numbers on St. Lazaria, and in smaller numbers on islands. off Biorka. Uria troille ealiforniea. California Murre. Common on salt water every- where. The only nesting colony visited was in a large cave on St. Lazaria Is- land. This colony numbered about three hundred pairs. The young were nearly all hatched by August 15. Stercorarius parasiticus. Parasitic Jaeger. Not noted at all during 1912, but during 1913 seen on Sitka Bay as follows: Two birds near St. Lazaria Island July 24, and one bird at ,Crab Bay, Kruzof Island. August 27. On September 9 the species was fairly. common in Chatham Straits on the east side of Baranof Island. Rissa tridactyla pollicaris. Pacific Kittiwake. According to Merrill, this bird occurs throughout the year in the vicinity of Sitka. It was very plentiful every- where on salt water during the time I spent'in the section. Although birds in adult plumage were common throughout the summer, no evidence of their nest- ing was found. Larus hyperboreus. Glaucous Gull. Merrill secured an immature bird of this species at Sitka, November 3, 198- I did not note it in this locality, but saw several birds along the mainland shore between Juneau and Petersburg, October 6-7, 1913. Larus glaucescens. Glaucous-winged Gull. Abundant resident. Accord- ing to Merrill, less plentiful in winter than in summer. I found this species nest- ing in considerable numbers on St. Lazaria and on small islands off Biorka. Larus argentatus. Herring Gull. This gull was first noted at Sitka, October. 2, 1913, several birds appearing in the harbor on that date. During the trip from Sitka to Seattle, October 2-o, these birds were abundant, and a large number followed the boat all the way. This is probably a regular migrant. Laxus brachyrhynchus. Short-billed Gull. Two birds seen in Sitka Harbor, October 2, 1913. Also noted at Juneau, October 5, and at Petersburg, October 7. Probably a regular migrant throughout the region. Secured at Sitka b> Bischoff during the Russo-American Telegraph Expedition (Dall & Bannister, 1869, p. 305). Noted by the 19o7 Alexander Expedition at Red Bluff Bay, Baranof
