It's Midsummer and we're at something of a turning point in the natural world. Following the launch of our Gardenwatch, House Martin and Garden Moth surveys last week, Philippa and Brett discuss some of your sightings. John Altringham is down in the cemetery with the Daubenton's Bats, we take another look at Cuckoos and we have a special report from Delaware Bay in Washington State, US where Red Knots have been feasting on Horseshoe Crabs.
