The naturalist, broadcaster, author and campaigner has announced he is taking a three-month sabbatical from his TV work to give himself some ‘brain space’.

After rising to prominence in the 1980s as a presenter on the BBC children's TV programme The Really Wild Show, Chris Packham has spent nearly four decades exploring and explaining the natural world on our screens. Along the way he's written books, fronted numerous environmental campaigns, and also raised awareness of living with Asperger's Syndrome.

Mark Coles hears from Chris Packham's family, friends and colleagues about his life and career.
