The importance of breeding bird surveys (BBS) has been illustrated by the popularity of the North American BBS program as well as the number of research projects that focus on declining neotropical migrant populations being conducted both in North America and abroad. Isle Royale National Park, Michigan, established a formal breeding bird survey in 1994 to integrate island population data with other studies being conducted in the region. This program continued in 1995, 1996, and 1997 with the objective of determining the size and composition of the neotropical migrant community on Isle Royale. This single objective approach represents a shift in focus from the 1994 survey. Point counts were conducted at Isle Royale NP from 14 June to 27 June 1997, using eight park trails as transects. A total of 122 points were surveyed. Species diversity values were calculated for each transect. A total of 58 species (1283 individuals) were recorded across the island. Three species were present at all eight transects, while 10 species were recorded at only one transect. Diversity values, by transect, ranged from 0.75 to 0.95 during the five minute counts. Comparisons between 1997 and 1996 are discussed. Recommendations are made for 1998 and include some suggestions to assist surveyors in locating points.
