A wildlife centre in Leicestershire says it is "overwhelmed" with the numbers of underweight hoglets.

An octopus has been filmed changing colour whilst sleeping, and scientists think it might be to due with it dreaming. So our eight-legged sea creature friends can dream, who knew? The footage, captured by PBS for an upcoming documentary Octopus: Making Contact, shows the mysterious creature asleep and changing from grey, to yellow, then almost invisible as it camouflages itself against the ocean.

The Trump administration has announced a plan to divert water to California farmers, fulfilling a campaign promise by the president, but contradicting federal biologists who found the plan would drive endangered salmon closer to extinction and could harm other fish.

In addition to devastating effects on bee populations and the pollination needed to feed humans and other species, widely-used pesticides chemically related to nicotine may be deadly to birds and linked to some species' declines, according to a new study.

If researchers can figure out how pigeons and rats evolve to thrive in hostile city habitats, it could help other beasts—including us—adapt to climate change.

Dozens of rainbow lorikeets have been flying into large glass windows at a Queensland university — some dying on impact — but a unique style of curtain has come to the rescue.

Slocan valley farmer Jim Ross spotted an unusual convoy on Monday as he pulled into a gas station near Salmo in the afternoon twilight — three B.C. government trucks and a stock trailer with plywood tacked over the slats. Intrigued, Ross asked the government employees what kind of animal was in the trailer while they filled up their vehicles at the snowy Centex station. He didn’t get an answer, so he asked again. And again.

The photographer tells CBS News the squirrel was a mother defending its babies – and she persevered

On Haida Gwaii, British Columbia, culling deer is an act of cultural and ecological restoration. By Leslie Anthony.

Thousands of adorable but poisonous Bufo toads, which can kill pets and are dangerous to children, have invaded a suburban Florida neighborhood. Cane toads, as they are known, range from 6 to 9 inches in length. Their babies are dime-sized, though, and those are the creatures hopping around in droves.

Karma's a bitch.

An African hunter who claims to have killed more than 5,000 elephants says he is 'totally unrepentant' about the deaths he has caused. Ron Thomson, 77, who worked in Africa's national parks for almost six decades, claims he was not hunting the animals for pure sport but was managing population that would otherwise have got out of control.

Ecologists long suspected the rugged mountains of Sailyugemsky National Park -- tucked into the Central Asian notch where Kazakhstan, Russia, China, and Mongolia meet -- were prime habitat for the beautiful, endangered snow leopard. But little was known about the numbers or habits of the elusive creatures. In 2010, American researcher Rodney Jackson of the Snow Leopard Conservancy donated 20 motion-activated camera traps to his Russian colleagues in hopes of learning more.

The gray wolf population in Yellowstone National Park has dropped to about 80 wolves, officials say — less than half of the high population mark in the park. While Yellowstone leaders won’t have an accurate count until the fall after surviving pups are visible, the park’s top biologist doesn’t expect numbers to rise dramatically after litters are included in population estimates.

“Pest” bird species such as crows, woodpigeons and jays can no longer be freely killed in England after the government’s conservation watchdog revoked the licence permitting it. The move by Natural England came after a challenge to the legality of the “general licence” by a new environmental group, Wild Justice, created by conservationists Mark Avery, Ruth Tingay and Chris Packham.

Give a mouse a wheel, and he’ll be sure to run. Lots of scientific studies have depended on that behavior to test the effects of exercise on health. There’s been some concern, though, that wheel running is not a natural behavior and thus not a good stand-in for human exercise. Maybe the captive mice are just acting out a neurosis, the thinking goes.

A previously extinct species of bird has re-evolved back into existence, according to a new study. The Aldabra rail first went extinct around 136,000 years ago. Now, it's reclaimed its home island. According to a study published Wednesday in the Zoological Journal of the Linnean Society, a peer-reviewed scientific journal, sediments from the Aldabra Atoll in the Indian Ocean show that the island has been completely submerged multiple times, wiping out all species inhabiting it.

Bird populations across the French countryside have fallen by a third over the last decade and a half, researchers have said. Dozens of species have seen their numbers decline, in some cases by two-thirds, the scientists said in a pair of studies – one national in scope and the other covering a large agricultural region in central France.

The number of seabirds on an island in the Bristol Channel has soared following the eradication of rats, conservationists have revealed. There has been a boost in the numbers of Manx shearwater, puffins and guillemots on Lundy Island 15 years after a project to remove rats ended. The RSPB said the number of seabirds on the island, off Devon, had tripled to 21,000.

The group of 35 will be shipped Down Under to protect the species from poaching.
