Abstract

Bald Eagles (Haliaeetus leucocephalus) congregate in Glacier National Park, Montana, each autumn to feed upon spawning Kokanee Salmon (Oncorhynchus nerka). Systematic observations and censuses of these eagle concentrations were initiated in 1965. McClelland (Condor 75:121-123, 1973) reported the results of the censuses for 1965-1966 and 1968-1970. From September to early December during 1971 and 1972 I conducted a study of the eagles in the same area, with special emphasis on recommendations for management. The purpose of this note is to present findings supplemental to McClelland’s, including the results of my censuses during 1971 and 1972, and censuses conducted during 1973 through 1977 by Park personnel.
