Clare Balding walks with the actor, and passionate bird-watcher, Samuel West around one of his favourite birding spots, the RSPB reserve at Rainham Marshes in Essex.
Currently in rehearsals for a West End production of Uncle Vanya, Samuel West takes a day off to share with Clare Balding his deep love of birding.
He's drawn to birdlife because, he says, it reflects human-nature so well, "birds interact with the world through colour and song, both of which we - as humans - really get."
A trip to Kenya at the age of 14 ignited this passion; "In Britain, birds were 3 inches long and brown.. in Kenya they were 7ft tall and couldn't fly, or bright blue... they were easy to tell apart... that's where it all started".
