Red deer graze following the end of the rutting season on November 12, 2014 in Glen Etive, Scotland. The rutting season sees the large red deer stags compete against each other for mating rights and can be heard roaring and bellowing in an attempt to attract the hinds. The rut draws to a close in early November when the males will spend the winter feeding to regain strength for the following year's season. (Photo by Jeff J. Mitchell/Getty Images)

A tranquilised golden lion tamarin is inspected, weighed, and measured in the lab by a research biologist. These are the adorable images of a group of endangered monkeys having their regular health check up. From having their weight checked in tiny scales to measuring their size the cute creatures are happy to follow doctors orders. The golden lion tamarin is endangered with less than 4,000 believed to still be living in the wild. Spread across three locations on the coast of southeastern Brazil, tamarins are regularly monitored to aid the growth of the species. Photographer Jami Tarris travelled to the Atlantic Forest in Rio de Janeiro to photograph the mammals. (Photo by Jami Tarris/Caters News)

Undated handout photo issued by The National Trust of one of the first seal pups of the season to have been born at the site of one of England's biggest colonies, Blakeney Point, on the north Norfolk coast. Grey seal numbers at Blakeney Point have grown steadily since 25 pups were born there 13 years ago. Last winter, 1,566 pups were born and with numbers increasing by about 25% each year, it is expected to become the biggest colony in England. (Photo by Justin Minns/PA Wire/The National Trust)

A adorable bear cub cant get enough of playing buckaroo – as it hangs onto its mum splashing about in a river. His mum was attempting to catch a fish supper for the pair as the plucky cub continued to jump on her back. And as she was concentrating on her meal the young bear became a distraction. So she sprung into life with him on her back before he was tossed into the water much to his delight. (Photo by Lisa Sidorsky/Caters News)

The giraffes dancing. When it comes to dancing these giraffes are definitely head and shoulders above the rest. The beautiful creatures appeared to be performing an elegant dance routine as they crossed their necks and swayed in time to the music in a series of synchronised dance moves. Despite their size the giraffes appeared to create perfect symmetry in what looked like a graceful dance routine. (Photo by Andrey Gudkov/Caters News)

A one-week-old female baby Sumatran elephant is seen next to her mother, Siska, at the private Taman Safari zoo in Pasuruan in eastern Java island on November 14, 2014. The baby, born on November 6, was succesfully bred in captivity as part of conservation efforts for the critically-endangered Sumatran elephant. There are fewer than 3,000 Sumatran elephants remaining in the wild, according to the International Union for Conservation of Nature. According to conservationists rampant expansion of palm oil, paper plantations, and mines, has destroyed nearly 70 percent of the Sumatran elephant's forest habitat over 25 years and the animals remain a target of poaching.

A snow-covered horse grazes a pasture near Cremona, Alta., Sunday, November 9, 2014, during the first heavy snow fall of the season. Heavy snow and plunging temperatures are expected to hit the Upper Midwest section of the United States this week, leaving as much of a foot of snow in its wake and pushing thermometer readings down 20- to 40- degrees overnight, part of a system being pushed in by the remnants of Typhoon Nuri that hit Alaska's Aleutian Islands with hurricane-strength winds over the weekend.

Two 18-month old lion cubs are seen at the Antelope Park, in Gweru, Zimbabwe, November 8, 2014. Lion walk was introduced to Antelope Park over a decade ago as part of an on-going conservation program to save African lions, whose population had dropped about 70 percent in the past two decades to estimatedly 320,000. Only cubs aged below 18 months are taken for lion walk. Once they grow older, human interaction is limited. The big cats will be groomed for release into the wild once they acquire the hunting skills and grow an edge to secure food against competitive predators like hyenas. (Photo by Caters News)
