Chris Packham investigates what enables birds of prey to rule the aerial roost, and reveals that their ability to dominate their fellow birds in terms of strength, manoeuvrability and phenomenal speed is down to a combination of anatomical and physiological adaptations. He explains the inner workings of the bald eagle's ratchet talons, and how sharp eyes and a gyroscopic head enable the goshawk to keep its sight firmly fixed on both its prey and its surroundings
