How many birds die from wind mills every day?

The number of birds that die from collisions with wind turbines varies and depends on several factors, including the location and size of the wind farm, the species of birds present in the area, and the weather conditions. According to the American Bird Conservancy, an estimated 440,000 to 500,000 birds are killed by wind turbines in the United States each year. However, it's important to note that this number represents a small fraction of the overall bird population and that wind energy is still considered a relatively clean and sustainable source of energy compared to other forms of power generation.
