Researchers from the University of Oldenburg and University of Oxford have found electromagnetic fields disrupted the migratory path birds are born with. The fields that were used in the study were under the recommended World Health Organization (WHO) standards.
During a study, researchers attempted to find out which the part of European robins’ brains that helped them navigate north. For two years, the robins flew immediately north when freed from their cages. In the next three years, the robins flew in all different directions. The researchers started a new study to explore why this was happening. When the robins were released from a Faraday cage, they flew immediately to the north. When the cages were inundated with low-level broadband noise while letting the robins free, these birds also had no sense of direction.
