On a summer walk in Upper Teesdale on her way to the great Cow Green Reservoir, nature writer Anita Sethi realises she is lost. Without her map, she turns to nature for a sign of where she is, and is rewarded with the call of the dunlin.
Once known as the red-backed sandpiper because of their rusty-red and black summer plumage, dunlins are small waders that nest on upland landscapes in the summer months, where peaty pools provide habitat for food. In the winter, their plumage transforms to greyish-brown and white. They can also be found on the UK's coastline and estuaries all year round.
Despite their relatively small size, dunlins are capable of producing a very loud song. Anita follows the bird's low burrs and high trills and eventually finds herself at the edge of the vast reservoir, nestled between the North Pennine hills - a perfect spot for birdwatching.
Presented by Anita Sethi and produced by Jo Peacey. A BBC Audio Bristol production.

Each year, CEO of the British Trust for Ornithology, Juliet Vickery, waits eagerly to hear the beautiful song of the willow warbler, which migrates from sub–Saharan Africa. However, on her own Cambridgeshire doorstep the willow warbler is increasingly rare. The fortunes of this delicate little bird in the UK is now one of a north-south divide - increasing in the North and West, decreasing in the South and East. Thanks to a network of volunteer observers, we now know this is, at least in part, because it’s breeding less well in the south than the north, almost certainly linked to rising temperatures in southern England caused by climate change.

Entomologist George McGavin remembers the first time he saw a hoopoe, an occasional visitor to the UK. The hoopoe is largely insectivorous, and watching it forage for crickets and grasshoppers, and probe deep into the soil for larvae, reminded George just how important insects are for the survival of the majority of birds.

In early summer at the Knepp Rewilding Project in West Sussex you're almost guaranteed to hear a turtle dove, one of the UK's rarest birds. Conservationist Isabella Tree writes how its gentle soothing sound tugs at the heartstrings, as today fewer than 3000 breeding pairs remain. But at Knepp, turtle doves can find areas of dense thorny thicket where they like to nest, and wildflower seeds to eat. Now every year they count 20 singing males, which is a quater of the population in Sussex.
