Two lions who were rescued from circuses in Colombia and Peru last year and transported to South African wild have been killed by poachers in Emoya Big Cat Sanctuary.

A WWF appeal aims to highlight the threat of habitat destruction and climate change on wild populations

Erin Johnson, 27, of Anchorage, was killed Monday by a black bear while she was doing contract work for Pogo Mine in Interior Alaska.This was the second fatal bear attack in a two day span.

To see how far we've come in restoring grizzly bear populations in and around Yellowstone National Park, consider: There are five times more grizzlies now than there were in 1975, when they were first protected under the Endangered Species Act. The area grizzlies roam has increased by half. And conflicts with bears attracted to landowners’ chicken coops now pose a greater threat than hunting.

Latest estimates show that there are 104 tigers in the Kaziranga National Park and Burachapori, about 250 km from here. In 2014, there were 83 tigers in Kaziranga. While 95 adult tigers were found in Kaziranga National Park, two adult tigers and their cubs were found in Burachapori. Both the parks are located within the Kaziranga Tiger Reserve, sprawling over an area of 860 sq km.

Scientists reporting in the Journal of Mammalogy on May 30 have identified a new species of flying squirrel living in the Pacific Coast region of North America.

Mule deer, pronghorn and other animals rely on unbroken migration routes for food and survival, a necessity now in jeopardy as Trump pushes for development. By Oliver Milman.

'Extinction rates for birds, mammals and amphibians are similar to the five global mass-extinction events of the past 500 million years that probably resulted from meteorite impacts, massive volcanism and other cataclysmic forces'

Wolves and other top predators need large ranges to be able to control smaller predators whose populations have expanded to the detriment of a balanced ecosystem. That’s the main finding of a study appearing May 23 in Nature Communications that analyzed the relationship between top predators on three different continents and the next-in-line predators they eat and compete with. The results were similar across continents, showing that as top predators’ ranges were cut back and fragmented, they were no longer able to control smaller predators.

John Bevis explores the various feats of cunning and subterfuge undertaken by the Kearton brothers — among the very first professional wildlife photographers — in their pioneering attempts to get ever closer to their subjects.

Scientists in Denmark say that the country now has its first pack of wolves in over 200 years. Wolves hadn't been seen in the country in two centuries until one was spotted in Jutland five years ago. Since then, there have been concerns that male and female animals would meet and eventually mate, the Copenhagen Post reports. That now appears to have happened. DNA evidence from faeces has confirmed a female has settled in west Jutland, and CCTV images have shown a pair of wolves moving together in the region.

The Sun is rising on a calm and cloudy morning in late February 2017, and Jamie Sneddon and I have an important collection to make. After a short drive along the north-east coast of Scotland – passing open fields, detached bungalows, and blooming bushes of gorse that shine with a radiant yellow under the grey sky – we arrive at the muddy entrance of a farmyard. Many of the locals here in the remote Scottish Highlands are crofters: they nurture and trade certain root vegetables and small numbers of livestock and poultry, a lifestyle first developed in the 19th Century.

The animals tripped an alarm early Friday morning.

The world is hurtling towards the first mass extinction of animal life since the dinosaurs were wiped out 65 million years ago, according to the most comprehensive survey of wildlife ever carried out. By 2020, the populations of mammals, birds, fish, reptiles and other vertebrate species are on course to have fallen by more than two-thirds over a period of just 50 years, the Living Planet report found.

Conservationists don’t have enough money to save all the endangered species. How do we decide which ones live, and which ones die? A controversial new system for choosing may be coming to America soon.

One of the UK’s last killer whales, which was found dead last year, had some of the highest levels of a toxic pollutant ever recorded. By Rebecca Morelle.

A Canadian hunter is lucky to be alive after being attacked by a black bear. Richard Wesley was bow hunting near Fire River, Ontario, when he noticed a large black bear roaming nearby. At first, the bear seemed unfazed by Wesley's presence, but when the hunter makes a sound in an attempt to scare off the approaching bear, it charges.

Texas lawmakers have approved hunting feral hogs and coyotes from hot air balloons. The state already allows shooting feral hogs from helicopters. The latest hunting twist comes as the state looks for new ways to control a growing hog population that causes millions in damages to crops every year.

Officials are struggling to clear towns of toxic animals so that people displaced after the 2011 nuclear meltdown can come back. By Kimiko de Freytas-Tamura.

In northern New England, moose number about 70,000, but changing weather seems to be throwing the balance of nature off-kilter, giving an edge to one of the animal's most dangerous enemies — bloodsucking ticks. This has alarmed moose researchers, including Professor Peter Pekins, who is the chairman of the Natural Resources and Environment Department at the University of New Hampshire.

A study led by University of Tasmania researchers Cesar Tovar and Gregory Woods has shown that immunotherapy can cure Tasmanian devils (Sarcophilus harrisii) of the devil facial tumor disease.

A new breeding population of the critically endangered Indochinese tiger has been found in a national park in eastern Thailand, conservationists say. Camera traps discovered a small population with at least six cubs in the jungle. Poaching and the loss of habitat has reduced the global population of the sub-species to under 250. Conservationists said the success was due to the stepping-up of anti-poaching efforts in Thailand.

A Tauranga fishing boat skipper who was forced to release an estimated 30 tonnes of jack mackerel to save six dolphins caught in his net is being praised for his actions by fishing company Sanford Ltd - and by a boatload of recreational fishers who saw the drama unfold. "They tried their hardest to get them out of their net without losing their catch, because they had a huge amount of fish in there," said recreational fisher Paul Bowyer.

Photos of an owl swooping in with wings wide, eyes glowing and talons outstretched might not really be because of chance. Photographers using mice to lure the owls have caused a fierce debate.

We all know that animals need plants to survive, but most of us wouldn’t expect the culling of wild dingoes in outback Australia to have an effect on native grass. But a new study shows that’s not the case – removing dingoes has had a surprising effect on grass and other planet life on the Australian outback, and it’s created a cascade effect that’s led to an over-abundance of woody shrubs.

The price of raw ivory in Asia has fallen dramatically since the Chinese government announced plans to ban its domestic legal ivory trade, according to new research seen by the Guardian. Poaching, however, is not dropping in parallel. Undercover investigators from the Wildlife Justice Commission (WJC) have been visiting traders in Hanoi over the last three years. In 2015 they were being offered raw ivory for an average of US$1322/kg in 2015, but by October 2016 that price had dropped to $750/kg, and by February this year prices were as much as 50% lower overall, at $660/kg.

The 1967 article “A Close Look at Wildlife in America” both defines and reflects our growing concern for endangered species.

The herbivorous rodents kill off competing ground squirrels—the first such behavior seen in a mammal, a new study says.

The world's count of wild tigers roaming forests from Russia to Vietnam has gone up for the first time in more than a century, with some 3,890 counted by conservation groups and national governments in the latest global census, wildlife conservation groups said Monday.

A flying insect that’s suddenly swallowed by a bat probably doesn’t have a lot of time to reflect on its fate. If it did, though, it might wonder how on Earth the swooping mammal managed to grab it with so little warning.
