Chris Packham has insisted he never suffers from nerves before his live wildlife shows.

The presenter, 51, is back for an eighth series of Autumnwatch, with Martin Hughes-Games and Michaela Strachan.

“I never feel nervous, ever. It’s an hour-long conversation and you frequently have hour-long conversations in the pub, that’s the way I see it,” he said.

“I don’t prepare to talk to my mates down the pub. I go down there and see what’s happening and join in.”

The wildlife presenter said he wasn’t worried about finding enough material to fill the hour-long, live BBC Two shows.

“We’re always very confident we can produce a programme. If the animals don’t turn up or if it pours with rain it’s actually part of our story,” he said.

“In fact I can’t think of a programme over the series where we couldn’t have run it for another hour, because we’ve had so much material.

“I mean, I’d happily tell you about the life of a worm for five minutes if you’re interested, so there’s always something there.”

Autumnwatch runs on BBC Two from Tuesday, October 30 to Friday, November 2.
