Offshore energy development poses risk to birds due to collision mortality, lost foraging habitat, and energetic costs from behavioral disruptions. In this study, we used published habitat suitability and abundance models for seabirds, derived from vessel and aerial survey data, to determine spatially explicit exposure risk to energy development, at varying spatial scales within the Gulf of America. We summarized exposure risk across species, weighting each species’ exposure risk by population vulnerability, displacement vulnerability, and collision vulnerability scores to map risk. We developed quantitative risk scores for wind energy areas from combined metrics for exposure and vulnerability. We also assessed risk of energy development to migratory landbirds, based on a literature review and an analysis of incidental observations from pelagic boat surveys and birding excursions. We found that risk to seabirds from energy development is higher in the central Gulf, particularly adjacent to the coasts of Mississippi and Louisiana. For the endangered Black-Capped Petrel (Pterodroma hasitata), all wind energy areas had minimal risk scores, and exposure risk was greatest in the eastern Gulf. Landbirds generally showed greater risk from energy development in the central and western Gulf. Using Brown Pelican (Pelecanus occidentalis) and Northern Gannet (Morus bassanus) as a case study, we tested the effect of analytical spatial scale on risk quantification by comparing assessments from both federal and state waters in the region. The spatial scale of analysis influenced our results substantially, and risk scores for wind energy areas within federal waters differed depending on whether state waters were included or excluded from the analysis. Results from this analysis are compiled for use in decisions regarding offshore wind development and wildlife, and multiple assessment options are provided to allow decision-makers to assess concerns at local and regional scales.
