Birds of Northeastern Isle Royale National Park 1981-1994
Van Buskirk J and Smith DC. 1994. Birds of Northeastern Isle Royale National Park 1981-1994. Millbrook, NY
This account is based on records that authors have maintained for bird sightings at ISRO from 1981 through 1994. They kept a daily list in which they recorded the numbers of individuals of each species seen or heard during the previous 24 hour period. The duration of coverage varied among years; coverage was most complete from late May through mid-July, for which period we have at least 10 years' data. Records include 194 species, of which 21 do not appear in Shelton's 1982 pamphlet on the Vertebrates of Isle Royale. THe authors have indicated where breeding was confirmed in some species.
