Abstract:

This study was designed to isolate effects of electromagnetic EM fields produced by extremely low frequency ELF antenna systems on bird species breeding in or migrating through Wisconsin. Specifically, the aim was to determine any differences in bird species richness and abundance between areas close to the antenna and those far enough away to be unaffected by the antenna. Characteristics examined included total species richness and abundance, abundance of common bird species, and abundance of birds within selected guilds. Measurements of vegetation identified differences and similarities between control and treatment areas. Habitat variables were used in analysis of covariance ANCOVA to compare numbers of abundant bird species in control versus treatment areas after adjustments for habitat differences.
