Derek Mooney and guests explore the natural world in all its forms.

Classified as Red listed and a bird of high conservation value, The Ring Ouzel is thought to be down to a handful of breeding pairs in Ireland. Ornithologist Eric Dempsey reveals the story of this elusive species and the efforts being made to protect its fragile habitat.

Tonight, Terry Flanagan takes listeners beneath the surface of the International Basking Shark Conference, held at the Atlantic Technological University in Galway. The August event brought together scientists, conservationists, and ocean advocates from five continents.

Earlier today, a very special documentary was broadcast on RTÉ Radio One as part of our Nature on One series. Presented by Eric Dempsey, its subject was one of Ireland's most critically endangered breeding bird species: the Ring Ouzel, a close relative of the much more familiar Blackbird.

Of all of the ornithological surveys carried out by conservation charity BirdWatch Ireland, its annual Irish Garden Bird Survey is far and away the most popular. This winter's survey season – its 37th – will kick off on Monday 1st December and will run until the end of February 2026.

Proud Corkonian Jim Wilson is a man who feels very much at home on the open waves. Back in July, Jim travelled to Castlehaven Harbour to go night kayaking with Naoise and Jim Kennedy from Atlantic Sea Kayaking. He recorded a truly captivating report for tonight's programme.

Our good friend Collie Ennis, Biodiversity Officer with Trinity College Dublin, was in touch recently to inform us of something unusual...a walnut struck him on the head! Rather than fall from a tree, the walnut had apparently been dropped by a Hooded Crow. Terry Flanagan went to investigate.

Tonight's programme opens with Derek rifling through the entire back catalogue of Swedish pop sensation ABBA for one of their earliest songs - Ring Ring. They make a surprise call to listener Elizabeth Carney in Sligo but only get her answering machine!

Very sadly, a migratory species of wading bird called the Slender-billed Curlew has formally been declared globally extinct by the International Union for the Conservation of Nature and BirdLife International. Eric Dempsey talks about the lost bird and previews his upcoming documentary on The Ring Ouzel.

Listener Robert Brown sent us a photo of a robin with a crooked beak and we finally get through to Elizabeth Carney, who has questions about groups of crows on a beach and sandhoppers.

2025 marks the 5th anniversary of The Hare's Corner, a Burrenbeo Trust initative that helps landowners create space for nature through new habitats. Terry Flanagan went to Staffordstown in Meath to meet farmers Michael and Penelope Monaghan, Hare's Corner advisor Donna Mullen, and Michael's mum Walburga, who tunes in to us weekly at the age of 107!

BirdWatch Ireland's Cuskinny Marsh Nature Reserve in Cork has just added dedicated roosting islands for the wetland birds to sleep and shelter. Ornithologist Jim Wilson joins the programme to explain the additions.

Michele Browne went to Mizen Head to meet Mary McCarthy (and her father Paddy) to talk about how fishermen of old would look to nature for signs of the weather. Mary reads these signs so well now, that people contact her for short term forecasts. You can hear a longer version of Michele's report on the website.

Though rarely seen, owls play a quiet but vital role in Ireland's ecosystem. The next featured talk in Killarney National Park's 'Autumn Talks Series 2025' will be 'The Secret Lives of Owls in Ireland'. Alan McCarthy, Barn Owl Project Officer with Birdwatch Ireland, will give the talk.

The Edward Worth Library is a rare books collection, bequeathed to Dr Steevens' Hospital, Dublin, by Dr Edward Worth. It recently launched a web exhibition 'Birds at the Edward Worth Library' and Éanna Ní Lamhna was the speaker. Terry Flanagan went along to see this hidden treasure.

Éanna is taken with a new Irish version of 'Where the Tree Dogs Fly', an illustrated picturebook by Aileen Crossley. The author talks to Éanna about the new edition, An Áit a nÉitlíonn na Madaí Crainn, which is a 'love letter from mother nature to a troubled child'.

Listener Martin Murray from Waterford sent us in some lovely photos of a Glossy Ibis feeding. Ornithologist Eric Dempsey explains this interesting bird.

Dublin city hosts a secret world of wildlife. When Éanna Ní Lamhna's 'Wild Dublin: Exploring Nature in the City' was first published in 2009, it explored the surprising natural riches of our capital. Much has changed in 16 years and Éanna has now updated the book to reflect the new species, flora and fauna in the city.

Last Thursday (October 2nd) was National Tree Day, a special day organised every year by the Tree Council of Ireland for primary school pupils (and the rest of us) to discover how amazing trees are. Éanna is a former President of the Tree Council of Ireland and she tells us more about this year's celebrations.

The 'season of mists and mellow fruitfulness,' as John Keats put it, is well and truly with us. Have you noticed the vast amounts of fruits, seeds and berries around this year? That's because it's a mast year. Terry Flanagan went to meet Dr. Matthew Jebb, Director of the gardens at the National Botanic Gardens, to find out all about mast years.

Each year, Jeremy Turkington and his colleagues at Hometree collect seeds from native Irish plant species in order to propagate them and ensure their future and genetic diversity in Ireland. For tonight's programme, our researcher Michele Browne met him to find out more.

This year marks the 37th year of the annual Killarney National Park ‘Autumn Talks Series', which is set to return this Thursday (October 9th). We speak to long-standing organiser of the annual series of talks, Pádruig O'Sullivan, Conservation Ranger with the National Parks and Wildlife Service.

One of the most memorable songs in the wonderful musical 'The Sound of Music' – released a shocking 60 years ago! – is about the beautiful Edelweiss flower. It happens to be one of Derek's favourite songs, but why does he start tonight's programme by playing it? Keep listening and all will become clear.

When you are abroad and you see a beautiful plant, you might be tempted to uproot it or collect some seeds, and bring it back to your garden. We have one simple word: DON'T! Éanna Ní Lamhna explains the huge risks of introducing a non-native plant to the ecosystem.

The term “birdbrain” should not be seen as an insult. Many bird species exhibit remarkable intelligence and problem-solving skills. The New Caledonian Crow, for example, fashions hooks from twigs and uses these to extract beetle larvae from wood. We examine impressive skills from some of our feathered friends.

One of the most striking examples of intelligence, manipulation and cooperation in the avian world concerns the Greater Honeyguide, a species native to Africa that feeds on beeswax. Sanele Nhlabatsi, a researcher from the University of Eswatini, recently led a study about how the species enlist human hunters to help it find food.

Returning to the subject of invasive alien species, it is hard to imagine that some of these species might still be found for sale in some local garden centres around Ireland, but they are according to Noeleen Smyth, Assistant Professor in Environmental and Sustainable Horticulture at UCD.

Tonight, we hear a repeat of Dr. Ken Whelan's documentary on the Mayfly. Something strange is happening with mayfly populations. In this Nature On One special, fisheries scientist Dr Ken Whelan sets out to uncover the truth.

The Sustainable Futures Forum brought together experts in biodiversity, climate action, and education. Terry Flanagan explores Ireland's nature crisis with Seán Ronayne, Éanna Ní Lamhna, Niall Hatch, and meets voices from the EPA, Creative Ireland, and UCC students working across science, policy, and the arts for a sustainable future.

Derek and Niall discuss how we can identify different species through their distinctive features and calls, and we answer some of your questions.

Last month, the town of Dungarvan celebrated the unveiling of Crockery Mountain, a 45 foot wide mosaic made from donated cups, plates, bowls and mugs. It was created to encourage sustainability and avoid waste. Terry Flanagan had to pay a visit and he speaks to the artist, Sean Corcoran.

In the human world, we know that friendships are important. But a recent report in 'Proceedings of the Royal Society B', show that friendship is an important bond for gorillas studied in Rwanda. One of its authors, Victoire Martignac, tells us more.

Over the course of the summer, we received lots of positive emails from listeners about improved butterfly numbers. Terry Flanagan met lepidopterist Jesmond Harding of Butterfly Conservation Ireland to find out whether our optimism this year is justified.

Global Action Plan is an environmental charity that guides people on a journey of discovery to reconnect us with nature and with one another. Terry Flanagan, met with Hans Zomer, CEO of GAP, and Niamh Ní Iceadha, the charity's Education Officer, in the organisation's Ballymun GLAS gardens, where they outlined some of their initiatives.

BirdWatch Ireland is Ireland's largest wildlife conservation charity, with a nationwide membership of over 15,000. Those members all receive Wings, the NGO's main membership magazine, and the children's edition, Bird Detectives. Niall Hatch takes us through the key issues in both magazines this summer.

Ireland's historic Royal Canal, originally built in the late 1700s, is now home to the longest Greenway in the country which extends from Dublin to Longford. Author Tom Dredge speaks to Éanna Ní Lamhna about his new book about the waterway, 'Rambling Along the Royal Canal: A Journey into the Heart of Ireland.'

Among her many credits, Éanna Ní Lamhna is a celebrated and prolific natural history author, with many books under her belt. One of the most popular of those books is 'Wild Dublin – Exploring Nature in the City', which was first published in 2008. Excitingly, Éanna tells us that an updated second edition will soon be published.

Two of the most popular urban-dwelling creatures you may encounter at home or during your commute are the Red Fox and the Sparrowhawk. These two species just so happen to be the subjects of one of Ireland's largest street art projects at the Aviva Stadium. Terry, Richard and Niall decided to take a DART to the area to investigate.

Ornithologist, author and regular contributor Eric Dempsey has had Sparrowhawks on his mind too. In recent days, a newly fledged hawk has taken up residence close to his house in Co. Wicklow and has literally been screaming loudly for its parents to bring it food.

Brendan Fitzpatrick sent a voice note to tell us about an interesting music festival. This summer, Co. Wicklow is alive with the sound of Ancient Music in the Forest, a festival celebrating ancient, traditional and early music in the natural forest amphitheatre at Dorlindon Nature Sanctuary, Kilmacanogue, Co. Wicklow.

Tonight's episode of Mooney Goes Wild is a bit different. We decided to send Terry Flanagan and Niall Hatch off on a very special mission...to travel to Rathfarnham in Dublin and get up close and personal with the nocturnal Irish predators that visit Martin's back garden.

Breda Kelly wrote to us recently about her garden in Ballinteer, Dublin. She has a diverse garden... but apparently a total lack of bees. In fact, she notes that all other insects are “as rare as hen's teeth” in her garden. Our panellists discuss.

While Breda may be lacking insects around her home, Niall tells us that he has the opposite problem at the moment: Common Wasps are nesting in a cavity below the front door of his house.
