Time to rethink orangutan conservation, now we know that our red relatives are actually very adaptable.
A feral cat snapped by a remote camera in the wild.

It's becoming harder and harder for animals to find human-free spaces on the planet. New research suggests that to try to avoid people, mammals are shifting activity from the day to the nighttime.
People transporting gasoline by boat in Indonesia’s Kayan Mentarang National Park.
The world's national parks cover an area bigger than South America. But a new survey finds that one-third of this area is subject to pressure from human developments, potentially putting wildlife at risk.
Eyes in the sky: drone footage is becoming a vital tool for monitoring ecosystems.

Ecology is in the midst of a technological revolution. From tiny sensors that can be fitted to animals, to swarms of remotely-piloted drones, researchers have a host of new ways to study the natural world.
Tundra swans, which nest in the Arctic and migrate south in fall, alight at Mattamuskeet National Wildlife Refuge in North Carolina.
The Interior Department is narrowing protection for migratory birds to cover only deliberate harm such as hunting, but not threats like development or pollution that kill millions of birds yearly.

Rhino resurrection is tempting, but if humans cannot save a species in nature, what future for animals that we manufacture?
The last male Northern white rhino died in February. Two females remain, but extinction seems likely.
We can't save all endangered species, but we could save some. Zoo populations will be the last hope for many threatened species.
Ocelot of trouble.
Three researchers studied the "crop raiders" of the Brazilian rainforest in the hope of aiding both local farmers and wildlife conservation.
The thorny devil, one of Australia’s many remarkable and unique animals.
Most of Australia's plants and animals are found nowhere else on Earth. This remarkable biodiversity requires a bolder, brighter conservation vision.
Most Australian kangaroo species, such as the bettong, are largely out of sight and out of mind.
A new documentary makes some controversial claims about the health of kangaroo populations. But the real threat is not to Australia's iconic kangaroos -- it's to dozens of other, obscure species.
Biofluorescence makes researching cryptic species such as this Lizardfish easier and less harmful.

Much of the world's ocean is teeming with 'cryptic' fish species, which are small and hard to spot. But a new technique shines a light on these fish, which may in turn help to keep our seas healthy.
