Killing the Skydancer: episode two, The Perfect Crime

In this special Age of Extinction mini-series from Science Weekly,
Guardian biodiversity reporter Phoebe Weston explores the murky
world of the illegal killing of birds of prey on grouse moors, and
asks why it is so difficult to solve these crimes. In episode two,
Phoebe speaks to the people trying to protect these rare birds, but
as she digs deeper encounters a surprising silence around the
killing of Susie’s chicks. Help support our independent journalism
