Recycling Tokyo Crows Build Their Nests Out of Coat Hangers | Oddity Central - Collecting Oddities - http://www.odditycentral.com/animals...
"But perhaps the most amazing crow nests are the ones built around Tokyo, Japan. Twigs and other natural materials are hard to come by in the busy metropolis, so the birds settle for the next best thing, and that seems to be coat hangers. You have got to see pictures to believe it! A blogger had posted some of these images way back in 2005, after solving the mystery of the missing hangers from her back yard. But it isn’t just the one nest – it seems that Japanese Jungle Crows are compulsive collectors of hangers!" - Jessie
