Episodes

Liz Berry on the Rock Dove 05.07.2026

Poet Liz Berry writes about her love for feral pigeons or rock doves, and how they rule the roost in Birmingham. Produced by Sophie Anton for BBC Audio Production in Bristol.

Horatio Clare on the Grey Heron 28.06.2026

The writer Horatio Clare reflects on the many tales told about the grey heron. They were seen as birds of augury by the Romans, or with a religious bent by the poet Dylan Thomas, and for Horatio their appearance makes them seem like judges, rather aloof and out of touch. But Horatio has watched herons, and writes of their patience and spearing in catching fish, and the intensity of their concentra...

Anita Sethi on the House Sparrow 21.06.2026

As a child growing up in Manchester, nature writer Anita Sethi used to dream of becoming a bird and flying away to the hills and moors beyond the city. Always on the lookout for signs of nature thriving in urban parks and streets, one of her favourite birds to spot was the noisy and sociable house sparrow. With greyish-brown plumage and a loud, chattering song, house sparrows aren't particularly f...

Isabella Tree on the Cuckoo 14.06.2026

Conservationist Isabella Tree tells the story of a remarkable cuckoo called Sayaan, who in April this year returned to her home and rewilding project at Knepp for the third year running. They are part of the British Trust for Ornithology’s Cuckoo Tracking Project, putting GPS trackers on cuckoos so we can learn about their migrations and help conservation. Sayaan left his overwintering grounds in...

Roland Arnison on the Storm Petrel 07.06.2026

We join explorer Roland Arnison on a kayaking expedition to the outer Hebrides on a quest to record the call of the storm petrel. These small and elusive seabirds spend most of their time at sea, nesting on rocky isles around the western coasts of the UK. While camping on the coastline of a remote uninhabited island, Roland patiently waited through the night until he heard the digital trill of the...

Mike Dilger on the Whimbrel 31.05.2026

For Naturalist Mike Dilger the whimbrel has just as much star power as the curlew. He likes to spot whimbrel on the Severn estuary as they migrate north on route to their breeding grounds in Scandinavia, Iceland and Russia. But to see this wader at its best, Mike recommends heading to their solitary British breeding outpost in Shetland where whimbrel combine their distinctive piping call with a bu...

Juliet Vickery on the Woodcock 24.05.2026

The CEO of the British Trust for Ornithology, Juliet Vickery, describes an encounter with a patrolling male woodcock 30 years ago, watching it circle its territory from high in the sky. Apart from this display these waders are very hard to see, usually inhabiting dense woods and heathland, which also makes them hard to monitor. However thanks to generations of volunteer observers, we know that the...

Isabella Tree on the Nightingale 17.05.2026

Author and conservationist Isabella Tree began inviting friends over to hear nightingales at Knepp, her home and rewilding project in West Sussex, 15 years ago. Nightingales used to be associated with coppiced woodland, but at Knepp they’re thriving in dense, thorny scrub which provides protection for their nests, which they build a foot or so above the ground. Though nightingales are still one of...

Jack Baddams on the Spotted Flycatcher 10.05.2026

Ornithologist Jack Baddams remembers chancing upon his first spotted flycatcher nest at Creswell Crags in Derbyshire. He became hooked on them after that, and fitted the adult birds with coloured rings to see who had safely returned from Africa. Although the spotted flycatcher may not have the most interesting song, Jack was drawn to them by their behaviour, and the way they would dart out from th...

George McGavin on the Swift 03.05.2026

Entomologist George McGavin worked at the Oxford University Museum of Natural History for 25 years, where each year he looked forward to the return of swifts to their nest boxes. Produced by Sophie Anton for BBC Audio in Bristol.

Liz Berry on the Kingfisher 26.04.2026

Poet Liz Berry has been sailing the Shropshire Union canal on a narrow boat since she was young. She describes the canal winding out of Wolverhampton into beautiful emerald green cuttings, where if you're lucky you might see a kingfisher. The canal's shallow and slowly moving waters are perfect hunting grounds. For Liz the azure and copper flash of a kingfisher darting low across the water is a ma...

Roland Arnison on the Fulmar 19.04.2026

Explorer and wildlife filmmaker Roland Arnison has been kayaking along Scotland's west coast on a quest to record the sounds of seabirds. Of all the many species he's encountered, it was the fulmar that really captured his heart. Produced by Sophie Anton for BBC Audio in Bristol. This programme features audio recorded by Roland Arnison on the Isle of Mingulay.

Polly Atkin on the Grey Wagtail 12.04.2026

Non-fiction writer Polly Atkin tells the story of a magical moment when a grey wagtail joined her swimming by a waterfall in a tree-lined gorge. Produced by Sophie Anton for BBC Audio in Bristol. Featuring audio recorded by Jarek Matusiak from Xeno-Canto (Grey Wagtail -XC360715).

Jo Wimpenny on the Red Kite 05.04.2026

The zoologist and writer Jo Wimpenny shares a story of a close encounter with a red kite in the Chiltern Hills, which swooped in to steal some food. This has become a more common experience in the area with the bird's population having grown by over 1,000% since the 1990s. Jo points out that although the return of a species that lives so well alongside humans won't always be welcomed, it's helpful...

Jack Baddams on the Siskin 29.03.2026

For ornithologist and wildlife researcher for BBC's Springwatch, Jack Baddams, March is 'siskin season'. As a licenced bird ringer, he puts ID rings on wild birds so we can learn more about their lives. One of Jack's favourite bird encounters while ringing was during a bird ringing demonstration for the public. The crowd was fascinated by a female siskin with its delicate citrus green and yellow p...

Mike Dilger on the Cetti's Warbler 22.03.2026

Naturalist and TV presenter Mike Dilger remembers spending a bird breeding season 30 years ago surveying the Cetti's warbler. The Cetti's has a secretive nature, and like most birders Mike is more familiar with its explosive song rather than it's appearance, which has been described as ‘someone dropping a saxophone in a reed-bed’. Since Mike's foray into the world of conservation science in the mi...

Juliet Vickery on the Dipper 15.03.2026

CEO of the British Trust for Ornithology Juliet Vickery fell in love with dippers while studying them during her PhD in south-west Scotland. She finds them packed full of character, and perfectly adapted to life between water and land. Dippers have to make sure their complex song is heard above the sound of rushing water, and for Juliet the combination of bubbling bird song and bubbling brook is c...

Roland Arnison on the Manx Shearwater 08.03.2026

In 2024 and 2025 expedition leader and film-maker Roland Arnison kayaked along the west coast and isles of Scotland to find and record the sounds of seabird species. As part of his quest he stopped on the island of Lunga, a protected area for its breeding seabird colonies and incredible place to spot them. One night Roland climbed the cliffs to find a colony of Manx shearwaters and recorded them c...

Horatio Clare on the Buzzard 01.03.2026

The writer Horatio Clare remembers the buzzards of his childhood, which soared above his home in the Black Mountains in south Wales. Produced by Sophie Anton for BBC Audio in Bristol.

Liz Berry on the Wren 22.02.2026

Poet Liz Berry lived near the Wren's Nest Nature Reserve in the Black Country for years, but it was only recently that she stopped and listened to a real wren there. It made her think how the bird was hiding in the place name, which is one of Britain's most important geological sites. The wren's latin name Troglodytes troglodytes means 'cave-dweller', reminding Liz of the folk that used to work in...

Hannah Stitfall on the Long-tailed Tit 15.02.2026

Every Spring wildlife filmmaker Hannah Stitfall heads out to look for long-tailed tits. She hopes to film them building their nests - intricate, domed structures built out of moss, feathers and spider silk. Unlike many other small birds, the long-tailed tit is capable of cooperative breeding, and will help relatives raise their chicks if their own don't survive. For Hannah the long-tailed tit is o...

Polly Atkin on the Long-eared Owl 08.02.2026

The non-fiction writer Polly Atkin is particularly fond of owls. Tawny owls surround her home in Grasmere in Cumbria, and she has observed the wintering of short-eared owls at the coast. One which remains elusive is the highly secretive long-eared owl, which Polly has never seen in the wild. Considered to be thinly but widely-spread in the UK, they are a scarce breeding species and very difficult...

George McGavin on the Gannet 01.02.2026

As a child, the entomologist George McGavin found a dead gannet on the beach, and set about extracting the skull for his collection. He was fascinated to discover the hundreds of pointed barbs in its mouth. Now years later he marvels at this clever bit of evolution which prevents fish falling out of gannets' beaks as they dive into the water then become airborne again. Produced by Sophie Anton for...

Juliet Vickery on the Brent Goose 25.01.2026

CEO of the British Trust for Ornithology Juliet Vickery is particularly fond of brent geese, having studied them on the Norfolk coast for three winters. They are our smallest goose, which migrate from the Arctic Circle every year. She describes what she learnt about fluctuations in their population, and the fascinating connection with lemmings in the Siberian tundra. Produced by Sophie Anton for B...

Horatio Clare on the Rook 18.01.2026

The writer Horatio Clare has a message from the rooks, pointing out the ways they differ from crows. Produced by Sophie Anton for BBC Audio in Bristol. This programme features audio from Xeno-Canto recorded by Olivier Swift (Rook - XC703729)
