Episodes

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)

Tolga Aktas on the Jackdaw 04.01.2026

Conservation biologist Tolga Aktas shares his fascination with watching jackdaws. He was struck by the contrast between its black plumage and piercing pale eyes, which they likely use as a communication tool. Jackdaws form large, noisy communal winter roosts with other species, and aren't afraid to mob predators behaviour which Tolga finds spectacular to see. Presented by Tolga Aktas and produced...

Polly Atkin on the Short-Eared Owl 28.12.2025

The poet and non-fiction writer Polly Atkin observes the wintering of short-eared owls in Cumbria. They are the UK's most nomadic owl, with residents joined by migrants from Scandinavia, Iceland and Russia, seeking a gentler version of the season. Fellow owl-lovers have told Polly of the moment they arrive exhausted at the coast, and she has watched a pair nest in a building site near the sea, con...

Liz Berry on the Robin 21.12.2025

For poet Liz Berry, December is the robin's month, when our hearts are warmed by its singing under frosty streetlights. She wonders if its midwinter song is one of the reasons why we feel close to robins, and imagine them as our companions in the thin places between living and dying. Liz tells the story of how the robin brought her hope during a difficult pregnancy, inspired by its fierceness and...

Horatio Clare on the Pheasant 14.12.2025

The author and journalist Horatio Clare reflects on the cultural history of the human relationship with pheasants. Its Latin name Phasianus Colchicus links the pheasant to the ancient kingdom of Colchis on the shores of the Black Sea, made famous in Greek mythology as the land of the Golden Fleece. These large, colourful long-tailed birds are native to Asia, and likely journeyed to western Europe...

Paul Farley on the Starling 07.12.2025

In the season where starlings gather to murmurate in our winter skies, poet Paul Farley is admiring this dazzling bird up close. Every spring a pair of starlings used to nest in a hollow wall in the house where Paul grew up, and he never got tired of studying its dark iridescent plumage. Laying in bed at night Paul would hear the starlings' impressive mimicry, and remembers the sound of a radio be...

Amy-Jane Beer on the Carrion Crow 16.11.2025

When nature writer Amy-Jane Beer moved to her current home, it seemed like the perfect rural dream. However, there then came an insistent knocking sound every morning - a pair of carrion crows would tap the windows, affronted by their reflections. Amy describes watching and learning to love these birds, which she sees as her quirky, idiosyncratic neighbours. Presented by Amy-Jane Beer and produced...

Polly Atkin on the Tawny Owl 09.11.2025

The home of poet and non-fiction writer Polly Atkin is surrounded by tawny owls. They are the most common owl in Britain, ranging from 20,000 to 50,000 breeding pairs, though we don't know exactly how many. Polly describes hearing the first melancholy call of a tawny owl in autumn, echoing around the lake at Grasmere. Kept awake by chronic illness, the owls' nighttime calls remind Polly that we ar...

Paul Farley on the Shelduck 02.11.2025

Poet Paul Farley welcomes the return of the shelduck to our shores, back after their summer migration to the Wadden Sea. These vast mudflats off the coast of The Netherlands and Germany provide a refuge for shelducks as they go through their so-called 'catastrophic moult' where they simultaneously loose all their flight and tail feathers. Paul imagines this vast gathering of around 200,000 birds a...

Roland Arnison on the Leach's Petrel 19.10.2025

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. His quest took him 40 miles out into the Atlantic to St Kilda in search of the Leach's petrel, one of Britain's rarest birds that only nests on a handful of offshore rocky islands. We join Roland scrambling up a cliff at midnight to h...

George McGavin on the Red-backed Shrike 12.10.2025

Entomologist and wildlife presenter George McGavin describes his lifelong fascination with the red-backed shrike. When George bought his first bird guide at the age of 10, this small shrike caught his eye because of its habit of impaling large insects and small vertebrates on thorns. This 'butcher bird' was once a common visitor to the south of England but was lost as a British breeding species by...

Paul Farley on the Redwing 05.10.2025

Poet Paul Farley muses on the autumnal arrival of redwings, small thrushes that migrate here from continental and northern Europe to spend the winter. Paul watches a flock of redwings feast on a rowan tree laden with berries, and listens out for their high-pitched nocturnal call as they move under the cover of darkness. Presented by Paul Farley and produced by Sophie Anton for BBC Audio in Bristol...
