Using Marine Bird Survey Data Collected From Three Large Vessel Survey Programs Conducted in the Southeastern U.s. and Gulf of Mexico, and for Up to 40 Marine Bird Species, This Project Will Construct Flight Heightprofiles (in Meters Above Sea Level) and Proportions (expressed in Percent) for Each of Several Marine Birdsthat May Be Attracted to Offshore Anthropogenic (man-made) Structures in the Gulf of Mexico. We Anticipatescreening All Species That Regularly Occur Within the Gulf Region, With a Principal Criterion Being the Ability Tosecure an Adequate Sample Size (more Than 10-20 Detections Per Species). Where Appropriate, Measures Ofcentral Tendency, Range, and Variability Will Be Calculated for These Flight Heights. in Addition to Calculating Thepercentage of Each Species Attracted to Offshore Anthropogenic Structures, a Breakdown by Each Structuraltype for That Attraction Will Be Made Wherever Possible (e.g., Fishing Vessels, Channel Markers, Navigationbuoys, Oil and Gas Platforms). These Data Will Help Usfws and Its Partners Better Understand Collision Andattraction Risks of Marine Bird Species Around Offshore Wind Energy Infrastructure.
