In some interesting studies that mix technology and nature new discoveries are being made. One study that places cameras on albatrosses shows how they find their food amidst apparently wide stretches of barren ocean: by following Killer whales. Some more details and other impressive albatross pictures can be seen here.
Another different study explains why birds are killed by power lines, no matter what you color them. These birds have blind spots that prevent them from seeing what is immediately ahead of them if they are at the same height.
