 November, t9o2. I THE CONDOR 39 There may have been other species of jegers at St. Michael but no specimens were taken. I, arus glaucescens Naum.--About the bay at St. Michael, these large gulls were always present. A few were seen at Cape Denbigh where they had nests, judging from their actions. Large gulls were common also at Dutch Harbor and there were a few about the beach'at Nome City. Rissa tridactyla pollicaris Ridgway.--This elegant gull was very abundant in St. Michael Bay from the time of our arrival, and considerable numbers were about the ship at all times. At Egg Island, July 4, they were nesting in a small colony apart from the tourres and puffins. Their nests were of dry weeds on the face of a low cliff. September 24 another visit was made to the same colony and the gulls were abundant, resting on their old nests. When driven off they sailed up the wind in a compact flock. About one-half of them were in immature plum- age. The species was nesting abundantly at Cape Denbigh. Sterna paradistea Brunn.---The arctic tern was observed most abundantly at Pathfinder Rock where several examples were taken July 7. A typical nest was a depression one inch deep by five inches in diameter, lined with dry grass and weed stalks. One nest was on top of a flat rock; all others were on the ground surrounded by grass. Occupied nests contained complements as follows: No. -- one pipped egg; No. 2--one pipped egg and one young; No. 3--two eggs, incubation advanced; No. 4--two eggs, incubation begun; No. 5--one egg, incubation ad- vanced; No. 6--one egg, incubation advanced. There were a great many empty nests, probably explained by the fact that some prospectors had been over the island. I found a dozen single eggs on top of a rock where some one had left them. They ranged from fresh in one'specimen to heavily incubated. Measurements of six of these are here given in inches and hundredths: .48x.6; .52x.o; .58xt.2; .6xt.t3; .65x.3; t.56xt.t6. The species was also secured at Toik Point and was seen in Norton Bay. A chick just out of the shell may be described as follows: throat black; breast white, becoming very dusky on abdomen; upper parts and flanks mottled with about equal parts of black and buffy; lining of wing white. Sterna aleutica Baird.--A single female of this species was secured at Path- finder Rock, where it was shot from a large flock of arctic terns. I believe the species was nesting on the island although no eggs were identified with certainty. Phalacroc0rax pelagicus robustus Ridgway.--As Bishop z records the Violet- green Cormorant from Whale Island, I refer all I saw to this species. They were seen in abundance only on Besboro Island, though a small colony may have nest- ed on Egg Island. A sprinkling of cormorants nested among the gulls and murres on the bold head of Cape Denbigh and single birds were seen at various localities along the coast. No specimens were taken. Anas b0schas Linn.--Numerous ducks were bought for the messes of our ship. The only species identified was a tnallard taken in September. Arct0netta fischeri (Brandt).--A single duck of this species was shot on Egg Island, September 24. When first seen it was resting on a point of rocks and was shot while swimming away. At St. Michael in July I saw a duck which may have been Somateria v-nirra. Somateriav-nigra. Gray.--Several downy ducks were taken on the ponds near Island Point, August 24. One of these has been identified as the Pacific eider by Dr. C. W. Richmond. t. N.A. Fauna NO. t9, Bds. of Yukon Region p. 6L
