Powerlines Disturb Animal Habitats

Wild animals see overhead power cables in remote regions of the countryside as disturbing lines of flashing lights, which could explain why many species avoid electricity pylons to the point where their natural territories become seriously fragmented, scientists said.  A study of wild reindeer in Norway has shown that they can see overhead power lines in the dark because their eyes are sensitive to the flashes of ultraviolet light which are invisible to the human eye but are constantly being emitted by high-voltage electrical transmission, the researchers said.
