This thesis is comprised of 3 parts: a feature article, a shorter communication, and appendices describing the tundra swans (Cygnus columbianus) summering in the northern Alaska Peninsula. The feature article titled "Populations, structure and Productivity of Tundra swans in the Northern Alaska Peninsula" presents findings from data obtained primarily from aerial surveys during the spring and summer 1969, and 1983-1987. The note, "Sightability Bias from Aerial surveys of Tundra swans in the Northern Alaska Peninsula", describes work conducted in 1986. The manuscripts have been prepared according to guidelines for The Journal of Wildlife Management (J. D. Gill and B. Healy, Wildl. Soc., Washington, D. C., 1980). All aerial surveys were completed with annual work plan funds from Alaska Peninsula and Becharof National Wildlife Refuges, USFWS, King Salmon, Alaska, in cooperation with the Office of Migratory Bird Management, Anchorage, Alaska.
