"We tried to change the food the birds were getting, the light, the cages — just about anything," recalls biologist Henrik Mouritsen. For the next three years, Mouritsen and his team tried to figure out why the robins weren't orienting. Nothing they tried seemed to work, until one of the scientists made a suggestion: maybe they should block the electromagnetic noise emanating from the electronics on campus, just to see. This was the moment that the researchers realized what no one had ever considered: the invisible lines of force that electronics constantly emit around us were actually disrupting the orientation capabilities of small migratory songbirds.
