Viewed through an amateur telescope, the Milky Way’s dusty center sweeps diagonally across the sky, draping stellar nurseries. Superheated by the massive black hole at the center of galaxy M87, a jet of gas shoots out across several thousand light-years.
A view through the massive galaxy cluster called Abell 1689 shows light from more distant galaxies smeared by the sheer force of Abell’s gravity.
F96, nicknamed Frostbite because of the loss of parts of her ears and the tip of her tail during the winter of 2012-13, is a young female mountain lion followed as part of Panthera’s Teton Cougar Project. But April showers and May flowers brought forth more than herbaceous growth—both grizzly and black bears emerged from winter slumbers in April of this year.

Bear kleptoparasitism (kleptoparasitism is science-talk for “stealing food from another animal”) is ubiquitous wherever bears and mountain lions overlap in North America.
But higher mountain lion kill rates in summer are explained by more than just bear kleptoparasitism—cougars kill more prey in summer because 1) they hunt smaller prey in summer (like deer fawns and elk calves), 2) higher temperatures increase invertebrate activity (which voraciously consume dead animals, Ray et al. F96 did abandon the bear-infested hillside to hunt elsewhere this past Spring, and then she more successfully consumed the prey she killed.
The studies described in this post were just published in Behavioral Ecology, and can be found here. We'll look for answers and post them here, along with regular updates about the science and conservation status of felids. National Geographic supports scientific research of lions, tigers, cheetahs, leopards, and other big cats with a view to finding viable ways to protect them in their natural habitat. Death is always near, and teamwork is essential on the Serengeti—even for a magnificent, dark-maned male known as C-Boy. Go behind the scenes of recent National Geographic coverage of some of the world's top predators. Gentoo penguins have plenty to be apprehensive about when entering Antarctica's frigid waters. Young royal terns, like this one learning to fly on a Florida beach, leave their nests within a day of hatching. Black-footed albatrosses like this male (right) and female on Hawaii's Tern Island may meet to dance and work on nest construction for several seasons before breeding, nurturing a bond that can last 20 years or more. King penguins have established colonies across seven islands and island groups in the southern reaches of the Indian and Atlantic Oceans. Dapper black-and-white razorbills (at right) and bright-beaked puffins (at left and in air, at center) find a haven on Scotland's Shiant Islands. Bright-beaked Atlantic puffins spend most of their lives at sea, speeding through the air at up to 55 miles (88 kilometers) an hour, darting underwater to hunt, or resting on the waves.
During the summer, kittiwake birds, like this one guarding eggs on Alaska's Prince William Sound, form cliffside breeding colonies that can be many thousand strong. Help protect the last healthy, undisturbed places in the ocean so we can learn how to help healthy reefs thrive, help unhealthy reefs recover, and better preserve the ocean. Explore the world's oceans, from their prehistoric beginnings to modern-day efforts to preserve their natural wonder.
Immerse yourself in the wonders of the deep through colorful maps, photos, and satellite images. The National Geographic Society’s freshwater initiative is a multi-year global effort to inspire and empower individuals and communities to conserve freshwater and preserve the extraordinary diversity of life that rivers, lakes, and wetlands sustain. The Florida Wildlife Corridor will be featured in America the Wild: Gator Country, starring Casey Anderson, Sept.
When National Geographic Television learned about the Florida Wildlife Corridor Expedition from National Geographic grantee Carlton Ward Jr, they extended their exploration of Florida’s Gator Country to discover the little-known wildlife habitat in the Everglades Headwaters.


Guided by Florida Wildlife Corridor Expedition member Joe Guthrie, America the Wild star, Casey Anderson, learns about the population of Florida black bears that inspired the Florida Wildlife Corridor Expedition and the habitat needed for their survival.
Guthrie and colleagues from the University of Kentucky lead the National Geographic crew into the field in partnership with National Geographic’s CritterCam program to produce never before seen footage through the eyes of a Florida black bear.

On January 10, 2015 we begin a new 1000-mile leg of our Expedition, to highlight a wildlife corridor from Central Florida to the Gulf Coast, through the Big Bend, and across the Panhandle all the way to Alabama, where our trek will conclude. We’ll document our journey the entire way, using social media to showcase imagery and reporting from the field. What's the fastest snake in the world?The deadly black mamba of eastern Africa can cruise at a speed up to 7 miles per hour (11.27 kilometers per hour) in short bursts.

Combining the fire of red with the serenity of blue, it has the ability to soothe as well as excite passion. She dispersed from her mother’s home range in May of this year, when she was 20 months old. Typically, the large male bears emerge first, followed by subadults, and then finally females with newborn cubs. She began hunting the cooler, forested north slopes—forests carpeted in an explosion of new green vegetation.
In a Colorado study, we found that black bears visited 48% of deer and elk killed by cougars in summer, and in a California study, they visited an amazing 77% of deer killed by cougars (Elbroch et al. So, when bears are around, cougars spend less time at kills, and less time between kills…both of which lead to more frequent killing of prey.
2014), and 3) higher temperatures increase how quickly meat spoils (Bischoff-Mattson and Mattson 2009). One possibility is that cougars seek out smaller prey during the summer bear season to mitigate competition with black bears over carcass remains, just like cheetahs do in the presence of African lions (Hayward et al.

Invertebrates outcompete vertebrate facultative scavengers in simulated lynx kills in the Bavarian Forest National Park, Germany. The mountain lions ability to overcome this is why I love these creatures they are determined and perseverance make for the perfect A pex cat predators.
It is essencial for their survival, But it is good to know that sometimes they are able to face and win over a bigger predator like black bears. There are 38 species of felids, ranging from the seven-pound tabby in your lap to 500-pound Siberian tigers—with cheetahs, leopards, ocelots, and other striped and spotted cats in between. We'll also share National Geographic articles, videos, and behind-the-scenes features and keep you up to date on our Big Cats Initiative work to help big cats hang on in the wild. Bloggers and commenters are required to observe National Geographic's community rules and other terms of service. Combining the resources of National Geographic and the Cincinnati Zoo, and drawing on the skills of an incredible crew, we documented these amazing cats in a way that’s never been done before. To reach the summer's bounty of fish, squid and krill, they often must negotiate a phalanx of hungry sea leopards. They gather with other hatchlings in groups called creches that can be thousands of birds strong.


These massive seabirds use a wingspan topping 8 feet (2.5 meters) to glide gracefully, often for hundreds of miles, using thermal updrafts to gain altitude.
As tall as three feet (one meter) and weighing an average of 30 pounds (14 kilograms), they are the second largest penguin, after the emperor.
It's estimated that nearly 8,000 razorbills and more than 200,000 puffins use these islands as their breeding grounds each year. They return to land each year to form breeding colonies, collecting twigs and grass to build their cliff-top nests.
During mating rituals, male birds show off their feet to prospective mates with a high-stepping strut. Robert Ballard, as he reveals the details behind this story of stealth, subs and superpowers. We’ll host a series of Saturday Trail Mixers, where followers can join the Expedition team and participate in our trek. Purple is prevalent in nature in everything from eggplants to amethysts, and humans have adopted it as a symbol of royalty.Here, snow-covered fir trees appear lilac during sunrise in Germany's Black Forest.
Spring bears are hungry, some of which have lost near a third of their weight while in hibernation.
Perhaps she didn’t know at the time, but this was also where black bears linger in Spring, grazing lush new growth like cattle and keeping cool in the shade. In one case in California, a large female mountain lion was displaced by an average-sized female black bear from a deer kill. And she wasn’t alone, bears stole carcasses from all the mountain lions we followed over the course of the summer. Prey preferences of the cheetah Acinonyx jubatus Felidae: Carnivora: morphological limitations or the need to capture rapidly consumable prey before kleptoparasites arrive? Perhaps it was a much larger tom that came upon and killed the black bear, caching it cat style beside the original kill. When a gannet spots a target, it folds its wings back and rockets downward, piercing the water like an arrow.
F96 successfully killed her first deer just 75 meters from a trail frequented by joggers and mountain bikers, and peacefully consumed it while concealed by tall sagebrush sufficient to hide her comings and goings. Thus, Spring and early Summer foods—like animal carcasses—are essential to bears for recovering depleted reserves quickly, before the distractions and energy expenditures associated with the mating season. F96’s next five deer kills were stolen by black bears, several within hours of when she made them.
In other words, cougars might hunt smaller prey so they can finish their meal rather than deal with the black bear(s) that inevitably shows up when there’s enough meat to attract their attention.
I watch animal shows a lot and see bears scare away other animals to eat after hibernating. What we found when we visited the kill a week later were the remains of the deer and bear, side by side. Where bears and cougars overlap, cougars suffer bears stealing their kills, and frequently.
Wolves, grizzly bears, people, condors (in the south) and occasionally packs of coyotes also push cougars from their kills. Typically mountain lions hear the approach of the bear, and don’t even stick around to spit and hiss.
