Birds vs. blades?

On a rainy March evening, three scientists climb aboard a small boat and head out onto the Chesapeake Bay. Their mission: to sneak up on seabirds sleeping on the water's surface, safely capture them, and bring them to shore so a team of veterinarians can implant high-tech tags and track them. Why? Because wind farms are coming to the Atlantic Ocean, creating much-needed renewable energy. Yet the Atlantic coast is also a migration corridor for millions of birds that are an essential part of the ocean food chain.
