A golden huddle by Minqiang Lu, China. Two females and a male golden snub-nosed monkey huddle together to keep warm in the extreme cold. Threatened by forest loss and fragmentation, this endangered species is confined to central China. Restricted to living high up in the temperate forests, these monkeys – here in the Qinling mountains in Shaanxi province – feed mostly in the trees, on leaves, bark, buds and lichen. In heavy wind and snow, Minqiang walked up the mountain carrying his equipment. He stayed for half an hour in temperatures of –10C opposite the tree where the group was huddled before achieving this eye-level composition. (Photo by Minqiang Lu/Wildlife Photographer of the Year)

The arctic hare, or polar rabbit, is a species of hare which is adapted largely to polar and mountainous habitats. The arctic hare survives with a thick coat of fur and usually digs holes in the ground or under snow to keep warm and sleep. Arctic hares look like rabbits but have shorter ears, are taller when standing, and, unlike rabbits, can thrive in cold climates. They can travel together with many other hares, sometimes huddling with dozens or more, but are usually found alone, taking, in some cases, more than one partner. The arctic hare can run up to 60 kilometres per hour (40 mph). Its predators include the arctic wolf, arctic fox, and ermine.

“I’d come to the Altai Mountains on an Adventure Sherpas tour. Our group of 12 was made up mostly of Minnesotans who’d left warm weather and falling leaves for frosty Mongolia. We’d come to sleep in cozy ger tents, the traditional yurt abode of the Mongolian steppe; sip mare’s milk tea; climb mountain glaciers; ride horses to an ancient battle site, and attend the annual Eagle Hunting Festival in Ölgiy...”. – Kathryn Kysar via The Star Tribune.

Captured by South African photographer Dillon Marsh, these fantastic photographs depict the many designs employed by sociable weavers to build sturdy nests that are safe from intruders such as cobras and tree snakes. They are also nice cool during the day, and stay warm during cold desert nights. A University of Stellenbosch graduate, Marsh is currently interested in landscape photographer who seeks out anomalies that can be arranged in a photographic series. Assimilation depicts scores of intricate weaver’s nests atop utility poles in Southern Africa. Colonies of sociable weavers have been known to stay attached to one particular nest for up to 100 years, according to The San Diego Zoo.

Female metro passengers hold flowers presented to them by metro workers, prior to International Women's Day in Kiev, Ukraine, 02 March 2016. The hustle and bustle of the morning commute is broken up by an unexpected surprise. The first passengers to step on the train receive – a warm welcome and a pot of flowers. One woman says, “It's very nice. All the running around and then you're given a flower, it's not often. It's very nice. I'm going to take care of this flower”. International Women's Day first emerged from the activities of labour movements at the turn of the twentieth century, in North America and across Europe, it is celebrated on March 08 in many countries around the world.

“A snapshot from mountaineer's life”. Have you ever wondered how does a mountaineer's day start? I will give you a hint: you wake up at 3 am, set the stove, wake up your partner, pretend it is warm, quickly consume a high-calorie breakfast, watch your friends slowly ascending the icy slopes of your dream summit with their tiny head torches glimmering against perfectly blue ice, and hope for the good weather. One would ask: why all this trouble? The answer is easy: for the love of the adventure and the unknown. Location: Chamonix, Haute Savoye, France.
