BIRDS. Glacier Bay, Alaska. June 27 to July 20 1907. Frank Stephens. Columbus holboelli. Holboell's Grebe. Saw two or three grebes, probably of this species = avitus s.c. Columbus nigricollis californicus. American Eared Grebe. Littlejohn and I killed one after a long chase among the Beardslee Islands. Gavia immer. Loon. G. arctica. Black throated Loon. G. lumme. Red throated Loon. A few loons are here but none were taken. I found one set of two eggs so badly incubated that they could not be saved. Lunda cirrhata. Tufted Puffin. Rather common. Breeding in small numbers in the upper edge of some gravel and sand cliffs in the smaller Beardslee Islands. One egg and one young bird taken. Other burrows opened were not finished. The summit of the cliffs was sod and this overhung the edge. The burrows were dug under the edge of the sod and ran back four or five feet, and were two or three feet below the surface. Fratercula corniculata. Horned Puffin. Dixon got two on South Marble Island and saw an egg that he could not reach. Synthliboramphus antiquus. Ancient Murrelet. Dixon shot one. Brachyramphus marmoratus. Marbled Murrelet. Common. Mostly in pairs. The females dissected were not ready to lay, possibly these were non-breeders as I shot two young birds out in the straits by themselves. B. kittlitzii. Kittlitz Murrelet. Rather common. Cepphus columba. Pigeon Guillemot. Common, single and in flocks. Stercorarius parasiticus. Parasitic Jaeger. Not common. Several shot. Rissa tridactyla pollicaris. Pacific Kittiwake. Common out in the bay among the ice.
