Evaluating Digital Vhf Technology To Monitor Shorebird And Seabird Use Of Offshore Wind Energy Areas In The Western North Atlantic, Pamela H. Loring

Doctoral Dissertations

Information on offshore movements of high priority bird species is needed for monitoring and managing adverse effects of offshore wind energy development in the western North Atlantic Ocean. This information is particularly important at night and during periods of inclement weather when risks of collision with offshore wind turbines may be elevated. For small-bodied avian taxa, technologies for monitoring movements of individually-marked birds are limited since satellite-based devices are still too heavy (> 5 g) for use on birds weighing < 150 g. In this dissertation, I evaluate the use of light-weight (1 to 1.5 g) digital VHF transmitters and a network of automated radio telemetry stations for tracking shorebirds and seabirds in offshore areas. In Chapter One, I compare digital VHF telemetry with satellite telemetry for tracking a shorebird, the American Oystercatcher (Haematopus palliatus), at nesting areas in coastal Massachusetts. In Chapter Two, I evaluate possible adverse effects and retention time …
