Blackouts Caused by Crews

Recently in Japan, there have been many unexplained blackouts. And this left many Japanese wondering about the cause. After much investigation, the cause of these blackouts has come to light. Apparently, crows building their nests using metal hangers are the cause. It is mating season for the crows, so, they have been building their nests on power poles. The metal hangers, which are good conductors of electricity, have been snagging the power lines causing these blackouts.
