As we approach International Dawn Chorus Day this Sunday (3rd May), we've decided to dedicate an entire episode of the podcast to our feathered friends. We meet the RSPB's Adrian Thomas, who orchestrated a top 40-charting single composed entirely of birdsong; RHS wildlife guru Helen Bostock offers advice on how to make your garden bird-friendly, and Dr John Grimshaw of The Yorkshire Arboretum shares his love of peafowl. Plus an unforgettable rook impression from RHS Chief Horticulturist Guy Barter.
