Nothing beats the sight of a top predator as it hunts. In the British Isles that means looking up. Our birds of prey are bouncing back after decades of shooting, poisoning and habitat loss. Buzzard numbers are up by 80% since 1995 and Red Kite by 2000%. Peregrine Falcon are thriving in London and Marsh Harriers have returned to our wetlands. Helen gets up close to Black Kites and an Eagle Owl at the Owl and Raptor Centre in Kent and travel writer Antonia Bolingbroke-Kent describes the extraordinary migration of tens of thousands of birds of prey through the Batumi Gap on the border of Georgia and Turkey. The RSPB's Mark Thomas and Robert Benson of the Moorland Association discuss the threat that birds of prey still face on some of Britain's shooting estates and Jennifer Ackerman, author of 'What An Owl Knows' joins Tom and Helen to explore the science behind the night-hunting skills of so many owls.
