The songbird’s dramatic decline in an ancient Cambridgeshire woodland is a story repeated across the UK as human activity drives species towards extinction

Richard Broughton has been nosing around this neighbourhood for 22 years. He gossips about inhabitants past and present, reeling off information about their relationship status, openness to visitors, brawls and neighbourly disputes. “They used to have a big punch up in spring here,” he says, pointing out where one family’s territory ends and the next begins.

Some areas are eerily quiet, with popular old haunts lying uninhabited. “I always get a bit of a pang now, walking through here and it’s empty. It’s like walking down your local high street and seeing your favourite shops are closed and the pub is boarded up.”

Anodyne children’s picture provides some gentle entertainment once you forgive the cloying anthropomorphism

‘Is that a butterfly fairy?” asks a confused seven-year-old who watches with me, pointing to the screen at the start of this Canadian animated tale. Nope. The purple creature with a humanish face and body, dressed in a hoodie, wings poking out of its back, is in fact the film’s rendering of a monarch butterfly. The film-makers behind this have really outdone themselves with their tackily revolting anthropomorphic butterflies. Still, if you can get past mutilating a wonder of nature, the movie is a harmless and rather sweet cartoon for under-eights.

Teenager Patrick is a monarch who cannot fly because of an undeveloped wing. His dad was a big hero in the community after pecking out the eye of a fearsome eagle (he paid the price too). But because of his wing, Patrick has been banned from taking part in the annual winter migration south to Mexico. Not this year, says his overprotective mum. (The film ignores the fact that the monarchs make their incredible epic journey only once.) So, Patrick turns stowaway, hiding in the emergency food supply with his chubby caterpillar pal.

Common eastern bumblebee queens’ ability while hibernating could help it endure flooding, scientists say

Bumblebees might be at home in town and country but now researchers have found at least one species that is even more adaptable: it can survive underwater.

Scientists have revealed queens of the common eastern bumblebee, a species widespread in eastern North America, can withstand submersion for up to a week when hibernating.

As the soundscape of the natural world began to disappear over 30 years, one man was listening and recording it all

Read more: World faces ‘deathly silence’ of nature as wildlife disappears, warn experts

The tale starts 30 years ago, when Bernie Krause made his first audio clip in Sugarloaf Ridge state park, 20 minutes’ drive from his house near San Francisco. He chose a spot near an old bigleaf maple. Many people loved this place: there was a creek and a scattering of picnic benches nearby.

As a soundscape recordist, Krause had travelled around the world listening to the planet. But in 1993 he turned his attention to what was happening on his doorstep. In his first recording, a stream of chortles, peeps and squeaks erupt from the animals that lived in the rich, scrubby habitat. His sensitive microphones captured the sounds of the creek, creatures rustling through undergrowth, and the songs of the spotted towhee, orange-crowned warbler, house wren and mourning dove.

The 2013 documentary Blackfish turned orca trainers into pariahs in the US. Now some are hitting it big in China

Some people spend a long time deciding what they want to do in life. Hazel McBride feels lucky that she’s always known. As a child in Scotland, she watched a VHS tape of Free Willy on repeat. That was the first time she felt a connection with killer whales . The second time was at age eight, on a trip to SeaWorld Orlando in 2000. Shamu was the animal world’s greatest celebrity, and in the US, SeaWorld ads were ubiquitous. Kids wanted to see the killer whales, and after they saw them, they told their parents they wanted to become killer whale trainers. McBride actually did it.

It wasn’t easy. Scotland didn’t have a SeaWorld, or warm water, or anywhere, really, where McBride could get experience with marine mammals. She had horses she cared for, and she was on the national swim team – a modest start. She sent out volunteer applications to local zoos and worked with California sea lions at a safari park. She reached out to trainers online and one told her a psychology degree would help, so she got one.

Loss of intensity and diversity of noises in ecosystems reflects an alarming decline in healthy biodiversity, say sound ecologists

Read more: No birdsong, no water in the creek, no beating wings: how a haven for nature fell silent

Sounds of the natural world are rapidly falling silent and will become “acoustic fossils” without urgent action to halt environmental destruction, international experts have warned.

As technology develops, sound has become an increasingly important way of measuring the health and biodiversity of ecosystems: our forests, soils and oceans all produce their own acoustic signatures. Scientists who use ecoacoustics to measure habitats and species say that quiet is falling across thousands of habitats, as the planet witnesses extraordinary losses in the density and variety of species. Disappearing or losing volume along with them are many familiar sounds: the morning calls of birds, rustle of mammals through undergrowth and summer hum of insects.

A five-day mindful adventure on the Knoydart peninsula – one of the last great wildernesses in the UK – offers the chance to fully unwind and leap into the unknown

It’s a relief to lay my rucksack down, plunge hot feet into the cool stream and pause to revel in the fairytale surrounds. Foxgloves stand tall against a cornflower-blue sky, ferns look almost luminous, the water glints in the early summer sunshine. A patch of moss-covered ancient forest provides shade, a cuckoo calls in the distance, mountains layer on the horizon.

I’m in Knoydart in the Highlands of western Scotland, one of the last great wildernesses in the UK, on a hiking and wild camping adventure. No roads cross the 22,000-hectare (55,000-acres) peninsula, a rugged place where a trio of Munros soar skyward, sandwiched between sea lochs Nevis and Hourn (poetically translated as heaven and hell). Over five days our group of eight will explore this land on foot, carrying our sustenance and shelter on our backs, led by two guides from The Living Project, Josh and Emily.

What can sound tell us about nature loss? Guardian biodiversity reporter Phoebe Weston tells Madeleine Finlay about her visit to Monks Wood in Cambridgeshire, where ecologist Richard Broughton has witnessed the decline of the marsh tit population over 22 years, and has heard the impact on the wood’s soundscape. As species lose their habitats across the world, pioneering soundscape ecologist Bernie Krause has argued that if we listen closely, nature can tell us everything we need to know about our impact on the planet

Paris claims ban breaches UK-EU trade deal but environmentalists say dispute is ‘hypocrisy’, given Macron’s rhetoric on saving oceans

France has been accused of hypocrisy by conservationists over a fresh post-Brexit dispute with the UK over fishing rights.

France launched an official protest after the UK banned bottom trawling from parts of its territorial waters last month, with the aim of protecting vulnerable habitats.
