Dorset cliff cameras fail to solve missing puffins mystery
Wildlife cameras have failed to explain why the last known colony of puffins on the south coast of England has failed to raise young.In 2023, naturalists noticed that the seabirds near Swanage, Dorset, had stopped bringing fish to their nests on the cliffs.They speculated that rats or crows had eaten the chicks.However, motion-sensor cameras installed at the site in 2024 have recorded no predators and have not provided any other explanation, the National Trust said.
More than 70,000 images were viewed from the cameras at Dancing Ledge.In 2024, the puffins were seen to build nests but did not deliver food, probably because their eggs did not hatch, according to the National Trust which manages the site.Marine ornithologist Dr Richard Caldow said: "It's disappointing that the cameras didn't reveal exactly what the problem is."This is important because it's the last known regular nesting site for puffins on the mainland of southern England."Sadly... without intervention, they are probably facing extinction here."
In recent years, only three nesting pairs of puffins have been seen at the site. However, a survey in 1958 recorded about 85 birds.This year, researchers are asking for local boat operators to help pinpoint exactly where the puffins are nesting.The National Trust and its partners plan to reinstate the cameras in 2026, with improved equipment and locations.

Yorkshire Dales project helping to save rare orchid from extinction
A project to bring back one of the UK's rarest wildflowers has shown its first signs of success, experts lady's slipper orchid was thought to be extinct by the early 20th Century, until a single plant was discovered in a remote area of the Yorkshire Dales in location was kept secret, with volunteers providing round-the-clock monitoring over several decades to prevent the plant being dug up and stolen.A scheme was launched two years ago to plant hand-reared orchids, with a plant discovered last June the first to germinate "of its own accord" since 1930, according to the Yorkshire Wildlife Trust (YWT). "The lady's slipper is a real icon of limestone habitats," Jonathan Leadley, from YWT, explained. "Where we've got limestone geology there's often a wealth of wildlife, but we've lost so much of the wildlife from these habitats."This is a real flagship, like a superstar."Efforts to boost the population began in the 1990s, with a plea for help that resulted in a small number of privately-owned, wild-sourced orchids being offered as part of a captive breeding were reintroduced to locations in the north of England - which were also kept secret to avoid the ongoing threat of theft - with the project led by YWT since were propagated in Kew Gardens' laboratory, with young plants then nurtured by a network of volunteer specialists managed by the National Trust. Mike Fay, Kew senior research leader, said it had been a "flagship" conservation scheme for many years."The appearance of a seedling is incredibly exciting and offers us hope," he Walker, from the Botanical Society of Britain and Ireland, paid tribute to the "hundreds of volunteers and enthusiasts who have carefully nurtured [the plant] back into the wild". Mr Leadley said that while "only a minority of people" stole plants, it was "certainly" still a threat."When all this effort is being put in by lots of people to try and bring a species back from the brink of extinction, we really don't want all of that effort to go to waste by a selfish individual pinching that plant," he said."We've got to keep it guarded for now, but hopefully at some point in the future there'll be so many of these plants out there that everybody will be able to enjoy them."

Farne Island 'puffin cam' attracts thousands of viewers
A webcam allowing people to spy on puffins has garnered tens of thousands of National Trust has set up cameras near puffin burrows and clifftops on the Farne Islands, off the coast of ranger James Porteus said viewers were "loving it" and that it was helping to end unequal access to said people were able to witness some "really amazing behaviour up close" and told viewers to keep an eye out for pufflings - baby puffins - leaving their burrows at dusk, previously rarely seen as visiting hours on the remote islands are restricted. The Farne Islands are a National Nature Reserve in England and an internationally important home to approximately 200,000 Porteus said viewers had seen puffins bringing fish into their burrows, opportunistic gulls trying to steal the catch, and "amazing sunsets" on the north-west facing camera."There's always something to watch," he said. Puffins have been facing growing threats including climate change, Mr Porteus said."They're a species that need our help," he manager for the Northumberland coast Daniel Wilson said the cameras were solar battery powered and look like a blended piece of were set up to capture the 2025 breeding season and were installed just before the first seabirds Wilson, who has been with the trust for about 20 years, said seeing the huge team project come to fruition was "incredibly rewarding".In the first three weeks of operation, the main puffin camera reached 90,700 views and the average watch-time is about five was an average of 25 people watching at any one time, the National Trust team said it intended to keep the stream going until at least the end of June.

People left with a 'headache' after discovering bizarre island-in-a-lake-on-an-island-in-a-lake-on-an-island - as one vents 'my brain cells hurt'
The remote regions of the world are full of some incredible and baffling mysteries. Now, one discovery, shared in a viral post on Instagram by @ has left social media users reeling. Located in remote northern Canada, this is the world's largest island-in-a-lake-on-an-island-in-a-lake-on-an-island. If that description sounds confusing then you're not alone, as Instagram users have flocked to the comments to complain that the island left them with a 'headache'. One frustrated user vented: 'That just scrambled my brains.' At the centre of this geological Russian nesting doll is a small, sea-horse-shaped island measuring just over 300 metres (1,000ft) long from end to end. That island is nestled inside a small unnamed lake which takes up most of the area of another larger island. This, in turn, is sat within a 55-mile (90km) lake located near the coast of Victoria Island, the eighth largest island in the world. Zooming out, you can see that this island is sat inside a larger, 55 mile (90km) lake One commenter said they 'literally had a headache' after trying to understand this strange island This island-in-a-lake-on-an-island-in-a-lake-on-an-island is what geologists refer to as a 'recursive island'. Geography buffs used to believe that the largest of these recursive structures was an island in a crater lake on Volcano Island in the middle of Lake Taal on the Philippine island of Luzon. But careful satellite analysis has revealed that the unnamed Canadian recursive lake is significantly larger. However, that exciting bit of trivia may have been lost on many social media users who have struggled to comprehend the island's tongue-twister-like description. On Instagram, one baffled commenter complained: 'I literally had a headache after reading this'. 'I had a stroke reading it,' another chimed in. Meanwhile another wrote: 'My brain is fried.' Even those who did manage to get their heads around the description still reported being left frazzled by the efforts, writing: 'I think I got it, but I think I pulled a brain muscle trying.' Even those who did understand what they were reading complained of pulling a 'brain muscle' while trying The island-in-a-lake-on-an-island-in-a-lake-on-an-island At the centre is a small island measuring 300m from end to end. That island is nestled inside a small unnamed lake which takes up most of the area of another larger island. This, in turn, is sat within a 55-mile lake near the coast of Victoria Island. Due to the island's remote location in the freezing Arctic, it is unlikely that anyone has ever set foot on this strange recursive island. Victoria Island, or Kitlineq as it is called by the Innuit residents, has a population of less than 2,000 people despite being larger than the US state of Idaho. However, Canada's unique geography means that this region is littered with recursive lakes. Canada is also home to the world's largest island-in-a-lake, Manitoulin Island in Lake Huron, and the largest lake-on-an-island, Nettilling Lake on Baffin Island. According to the NASA Earth Observatory, nearly all of Canada was covered by glaciers during the last ice age. As the glaciers moved, they carved out a network of channels and deposited small hills made up of glacial till, a mixture of clay, sand, and rock dug up by glaciers. Dr Daniel Kerr, a geologist from the Geological Survey of Canada, told NASA's Earth Observatory: 'This area became ice-free by about 8,000 years ago. 'But because of the weight of the ice sheet, the land was depressed and the waters of the Arctic Ocean flooded the land.' That left the region dotted with millions of small lakes, many of which had islands of them which, in turn, had their own nested lakes and islands.
