Harris's Hawk (IMAGE) Lund University Caption In many cases it is the color of the prey that helps predatory birds to detect, pursue and capture them. In a new study, biologists at Lund University in Sweden show that the Harris's hawk has the best color vision of all animals investigated to date -- and in certain situations, even better than humans. The findings may help to protect threatened birds of prey against hazards such as wind turbines and power lines.
