Sightings in Bristol Bay during the winter months were more numerous and are clustered in the northern portion of the bay. R. E. Gill (personal communication) has been studying bird and mammal populations year-round during 1976-1977 in Moller Bay using aerial and small-boat survey techniques. He has never observed Beluga in his study area. Gulf of Alaska Approximately 40 000 km of surveys have been completed in the Gulf of Alaska during the months of January, March, April, May, June, July, August, and October. Most sightings occurred in the Cook Inlet, especially in the vicinity of Tuxedni Bay. The Gulf of Alaska population has been considered to be. geographically isolated and therefore genetically distinct from the Bering Sea population (Sergeant and Brodie 1969), and we have no evidence to the contrary after fairly intensive surveys south of the Alaska Peninsula extending from Kodiak Island west to the Aleutian Islands. Similarly Murie (1959) and others observed no Beluga in this area. The range of this population, however, does extend outside of Cook Inlet. We have sightings of Beluga in March and July near Kodiak Island and another near the entrance of Prince William Sound in March. Recently a group of 21 animals was sighted during late May in Yakutat Bay (Calkins and Pitcher 1977). Historically, Beluga have been observed as far.
