The Impact of Wind Turbines on the Distribution of Wintering and Migrating Raptors
Renewable energy sources, including wind power, are rapidly expanding as governments aim to fight climate change. However, wind turbines may negatively affect surrounding wildlife. Raptors are birds of prey and are potentially susceptible to being negatively affected by wind turbines. Raptor collisi...

Renewable energy sources, including wind power, are rapidly expanding as governments aim to fight climate change. However, wind turbines may negatively affect surrounding wildlife. Raptors are birds of prey and are potentially susceptible to being negatively affected by wind turbines. Raptor collisions with wind turbines are well-studied, but the potential for their spatial displacement due to wind turbines has received less attention. Understanding both collisions and displacement is necessary to comprehend the overall effects of wind turbines on raptors. Amherst Island, Ontario, Canada is renowned for its number and diversity of wintering raptors. Wind turbines were built on the island in 2018. In this study, we used standardized surveys to record the presence, number, and precise location of raptors on Amherst Island during winter and spring migration for three years before (2015, 2016, 2017) and three years after (2019, 2022, 2023) the windfarm was built.
