This is a making of the “Carrion Crows of Sendai City – Project” I did at university of applied science . We had the task to illustrate a certain phenomenon of wildlife in urban environment. I picked the astonishing behaviour of crows in the Japanese city Sendai.
What makes the crows of Sendai so special?
They came up with an impressive solution to crack walnuts. Their beaks are not strong enough to open a nut. Because of this inability they started using the traffic to crack their nuts. the birds wait for the right moment to place their nut precisely at pedestrian crossings on the road. When the lights turn green the cars run over the nuts cracking them open. The birds wait for the lights to turn red again. Together with the pedestrian they hop into the road and pick up their opened nut without the danger of being run over by the traffic.
David Attenborough has filmed this fascinating behaviour as well: Click
