Australian scientist discovers ‘chocolate frog’ in New Guinea swamps

Litoria mira has been declared a new species, despite looking very similar to the Australian green tree frog

An Australian scientist has discovered a new species of frog, the “chocolate frog”, in rainforest swamps of New Guinea.

Steve Richards, a frog specialist at the South Australian Museum, first found the spotted the cocoa-coloured creature in 2016 in incredibly challenging habitat.

‘Accidental meat’: should carnivores embrace eating roadkill?

My parents have been eating pheasants killed on the roads for years and encouraging me to try them. Is this the most ethical approach to meat-eating?

Motorists shoot me funny looks as I sheepishly cross a scrubby verge, trying my best to conceal the dead pheasant under my arm. I am in a part of Saddleworth Moor called the Isle of Skye by locals, and have just collected a free meal from the middle of the road.

Nobody can agree on how this area of moorland, in the West Riding of Yorkshire, earned its nickname. Some think it comes from a Victorian navvy, who exclaimed in a broad Irish brogue: “Look, there’s an ’ole in the sky,” as he considered a parting in the thick mist above him. Others think it was named after an inn of the same name. But either way, the area should be immediately renamed Pheasant Cemetery. Because, before I picked up my own bird, I counted 46 pheasant carcasses in various stages of decomposition, scattered and splattered on the road over several miles as I drove to Holmfirth for a day out.

Sex-mad and spectacular: 17 incredible facts about cicadas

Once every 17 years, trillions of cicadas emerge from beneath the ground in the US. They taste like tinned asparagus, are sometimes attracted to power tools – and can number 1.3m an acre

Brood X is upon us. Across the US billions, if not trillions of cicadas have emerged from below the ground, a biblical plague that occurs every 17 years. Gene Kritsky wouldn’t miss it. “This is special,” he says. An entomologist at Mount St Joseph University in Cincinnati, Kritsky has studied periodical cicadas for nearly 40 years. Brood X, the subject of three of his books, holds a particular place in his heart. In the middle of back-to-back interviews during his busiest professional period since 2004 (“It happens, every 17 years”), he found time to share his favourite facts with us.

‘You care for birds, and they heal you’: film profiles world of a Black falconer

A new documentary, The Falconer, follows Rodney Stotts, who found fulfillment in working with raptors and inner-city kids

Falconry is a profession with roots in the ancient Middle East and medieval Europe but one of its practitioners is making some history of his own.

‘A huge surprise’ as giant river otter feared extinct in Argentina pops up

Conservationists thrilled at the sighting of the wild predator, last seen in the country in the 1980s

“It was a huge surprise,” said Sebastián Di Martino, director of conservation at Fundación Rewilding Argentina. “I was incredulous. An incredible feeling of so much happiness. I didn’t know if I should try to follow it or rush back to our station to tell the others.”

The cause of the excitement was the sighting, last week, of a wild giant river otter – an animal feared extinct in the country due to habitat loss and hunting – on the Bermejo River in Impenetrable national park, in north-east Argentina’s Chaco province. The last sighting of a giant otter in the wild in Argentina was in the 1980s. On the Bermejo, none have been seen for more than a century.

Startup’s bug idea – to put cricket tortillas and chips on the menu

Company founded by three Spanish friends hopes to tap into demand for new sources of protein

There are no gargantuan mastiffs or shepherds on quad bikes watching over the hundreds of thousands of newborn animals that tumble and crawl around an unlikely farm among the wind turbines, motorways and patchwork fields of this corner of Castilla-La Mancha, in central Spain.

Nor are there any fences to pen them in. Plastic tubs, shelves and the insulated walls of a unit on a windswept industrial estate do the job perfectly well. But whatever Origen Farms lacks in land, tradition and rural romance, it aims to make up for in innovation, enthusiasm and resilience.

Big cats seized by US authorities from Tiger King zoo in Oklahoma

Animal park that featured in 2020 Netflix series investigated in possible violation of Endangered Species Act

US authorities have seized 68 big cats from an Oklahoma animal park that featured in the 2020 Netflix series Tiger King, the Department of Justice has said.

In an affidavit of more than 50 pages, prosecutors said they believed a jaguar, seven lions, 46 tigers and 15 lion-tiger hybrids owned by Jeffrey Lowe and his wife, Lauren Lowe, had been sold, purchased or transported, which would be a violation of the Endangered Species Act (ESA).

Climate crisis behind drastic drop in Arctic wildlife populations – report

Native shorebirds and caribou among species at risk as survival strategies are upended

A drastic drop in caribou and shorebird populations is a reflection of the dire changes unfolding on the Arctic tundra, according to a new report from the Arctic Council.

The terrestrial Arctic spans approximately 2.7m sq miles (7m sq km), marked by extreme cold, drought, strong winds and seasonal darkness. Species living in this environment have adapted to thrive in the harsh conditions. But the climate crisis has upended such survival strategies, according to the State of the Arctic Terrestrial Biodiversity report, published by the council’s Conservation of Arctic Flora and Fauna (Caff) working group.

Snoring, slugs and sarcoptic mange: is it safe for cats and dogs to sleep on our beds?

Dogs can carry bacteria and parasites, while cats smuggle in gory ‘presents’. So is it best to lock them out of the bedroom?

Vomiting on the bed. Snoring. The shedding of hair. The stealing of sheets. The passing of wind. Night-time face-licking. A higher-than-average chance of catching sarcoptic mange …

If I could sit my dog down and quietly explain the risks associated with him sharing the bed with us, this is the list I would read to him. But I know he wouldn’t listen. Oz, our young lurcher, would only warmly reimagine that scene he recently saw. When, on my birthday, the family let him come upstairs and on to the bed to wake me up. When he saw, for the first time, Upstairs Land. And then widdled with joy.

Securing a swift return: how a simple brick can help migratory birds

Many swifts flying back to Britain will find their summer nests lost to building renovations. But bird bricks are offering them an alternative home

Eagerly anticipated by many, it is a thrilling moment when you first hear the distinctive screech or catch sight of the long, tapered wings of the first swifts arriving for the summer. For thousands of years they have looped to the British Isles from Africa to raise the next generation, taking advantage of the long daylight hours in the north and the opportunity to scour the skies for insects from dawn to dusk.

Since they left Britain’s shores in August last year, these remarkable birds will have flown some 14,000 miles without stopping; feeding, sleeping, drinking and preening themselves on the wing. The birds returning now are likely to be at least four years old – the breeders. They head straight back to their nesting holes under eaves or gaps in stone and brickwork that they claimed and defended last summer. Within a few days their mate will arrive and, having spent nine months living independently, they will start to preen each other’s feathers within the nesting hole, crooning softly and bonding once again.

World is home to 50bn birds, ‘breakthrough’ citizen science research estimates

University of New South Wales led study suggests six times as many individual birds as humans but that many species are very rare

There are about 50 billion individual birds in the world, according to new research that uses citizen science observations to try to estimate population numbers for almost 10,000 species.

The paper, led by scientists at the University of New South Wales, suggests there are about six times as many birds on the planet as humans – but that many individual species are very rare.

‘He grabbed the lead and said: give me the dog’: can pet detectives stop the rise in animal theft?

Dogs are more valuable than ever – which is why so many are being snatched. But some owners and pet detectives are fighting back

The village of Partridge Green in West Sussex on a gorgeous spring morning. The early mist has burnt off; a wood pigeon coos; a flurry of pink snow falls from a showy cherry tree; outside the butcher’s, an orderly, socially distanced queue has formed; a chap out for a morning spin motors along the high street in his vintage MG. It is, as my companion, Colin Butcher, says, a scene straight out of Midsomer Murders.

There are no murders today in Partridge Green, but it is a crime scene, and the crime is one that appears to be sweeping the nation. Butcher – ex-police (you can tell), then private investigator, now company director and chief investigator of The UK Pet Detectives – is on the case. He steps from his Range Rover wearing a fleece with an official-looking badge and “UKPD” emblazoned across the back; a twist on NYPD, except PD stands for Pet Detective. “I know the impact of seeing that UKPD – it’s such an international sign,” he says later, putting the jacket on before knocking at an address linked to his main suspect.

Wild boar corner Italian woman and steal her food shopping – video

A group of wild boar surrounded a woman who had just come out of a supermarket near Rome and stole her shopping, rekindling a debate about the animal's presence in Italian towns and cities. A video posted on social media shows the boar pursuing the woman in a supermarket car park in the village of Le Rughe before raiding the shopping bag she is forced to drop. Italian farmers have protested in recent years about wild boar wreaking havoc on their land and causing fatal road accidents

‘Beavers are just being beavers’: friction grows between Canadians and animals

Beavers cause internet outages, steal posts and even put 30 sq km of a town underwater – but experts say the animals have a profound effect on ecosystems

At first, the theft of wooden fence posts seemed like a crime of opportunity – amid soaring lumber costs, stacks of wood have gone missing from construction sites across North America.

But officers in the Canadian prairie community of Porcupine Plain, Saskatchewan, soon identified the culprit: local beavers had stolen the posts to build their dam.

Campaigners lose court case to stop Ugandan forest clearance

Court ruling gives go-ahead for sugar plantation in Bugoma forest, home to endangered chimpanzees

Conservationists in Uganda have condemned as “shallow and absurd” a court ruling that authorised the government to allow swathes of a tropical forest to be cleared for a sugar-cane plantation.

Three environmental groups had taken the government to court over a decision to allow Hoima Sugar Ltd to build on 5,500 hectares (13,500 acres) in the Bugoma Forest Reserve.

Cod almighty: how a ‘mythical’ Faroes delicacy has vanished

A giant cod that was once a fishing staple is now so rare it has become the preserve of a few fine diners

It was no ordinary cod that Teitur Christensen was preparing. The head chef at Barbara Fish House, one of four restaurants located in tiny wooden houses in Tórshavn, the Faroe Islands’ capital, Christensen was hosting what has become known as a “Bank evening”, because of the main dish. In the small cosy rooms of these ancient houses – one of which was built more than 500 years ago – his team was getting ready to serve what has become an almost mythical fish: the Faroe Bank cod.

The Faroe Bank cod’s reputation is partly built on its size. It is huge: a three-year-old specimen is already twice as large, on average, as the Atlantic cod. But it is also legendary because of its rarity. A genetically distinctive member of the cod family, it was once plentiful before being nearly fished to extinction. In 2008, all commercial fishing of Faroe Bank cod was banned. Only the Faroe Marine Research Institute (Famri) is now allowed to catch them, when its researchers survey the fish population twice a year.

Trillions of brood X cicadas move closer to emergence as soil temperatures rise

Great Eastern Brood set to emerge in the last two weeks of May and into early June, with hordes of bugs to push up from underground

Brood X, otherwise known as the great cicada hatching of 2021, is drawing closer as soil temperatures in some parts of America move closer to 64F (18C) – the trigger, according to scientists, for trillions of the insects to push up to the surface and into the trees to mate.

Officials suspect Goiat the bear of Catalan livestock attacks

Val d’Aran regional government in Spain believes there are ‘several indications’ animal is responsible

Experts are analysing samples taken from the scenes of four recent attacks on livestock in northern Catalonia to determine whether they herald the return of a brown bear called Goiat who has become notorious for his depredations.

Goiat, who was brought to the region from his native Slovenia in June 2016 as part of an EU project to consolidate the bear population in the Pyrenees, is loathed by many farmers in and around the Val d’Aran because of his taste for sheep, goats and horses.
