Autumnwatch 21 October - get involved
It's a packed show tonight... Chris and Martin report back on their visit to north Devon, exploring the moors, rockpooling on the spectacular coastline, and helping bring in the wild Exmoor ponies. There's an update on the migrating osprey chicks, and wildlife filmmaker Johnny Kingdom is on the trail of one of autumn's spectacles, the red deer rut.
And as always we'd like you to get involved. Chris, Michaela and Martin will be playing a mystery sound and if you can identify it, here's the place.
The man of the moor himself is paying us a visit in the studio tonight. So if you have a question for Johnny Kingdom to answer on Unsprung please post it here and we'll try our best to ask him. (We've already had some great ones - so thanks if you've already asked one.)
And finally, a chance to outdo Chris and help us solve a mystery? Down on Exmoor the wildlife cameramen filmed this grub emerging from an acorn. But even Chris has no idea what it is. Do you know what the unidentified creature is? Answers below please nature sleuths...
Can you identify this grub?
Update 25 October: Thanks to all those who got involved on Friday's show, whether on the quiz, IDing the mystery grub or asking a question. We're sorry we can't answer them all. If you missed it, the answer to the sound quiz was a badger snoring (which you'll have heard a lot of if you watched our Badgercam over the last week or so).
