The Winners Of The 2016 National Geographic Nature Photographer Of The Year Contest

A solitary bear sits on the edge of one of the Barter Islands. There is no snow, when at this time of year, there should be. In speaking with the locals in Kaktovic, they've noted that it's been an unseasonably warm winter, and that the ice will be late in forming this year. This will have an impact on the local polar bear population, when it comes time to hunt seals for their food in the winter months...

A colossal Cumulonimbus flashes over the Pacific Ocean as we circle around it at 37000 feet en route to South America.

This Green Meteor was captured while taking a time-lapse to document the urbanization around the Skyislands in India. The camera was set at 15s exposure for 999 shots and this came into one of those shots. Green Meteor’s greenish color come from a combination of the heating of oxygen around the meteor and the mix of minerals ignited as the rock enters Earth's atmosphere. I think for those 15 seconds, I was the luckiest photographer on the planet to have capture this phenomenon.

To restore original natural dynamics in streams many measures are necessary. In the 'Leuvenumse beek' a nature organisation tried to increase heterogeneity of the river bottom and water retention by putting dead wood in the streamsystem. In autumn when rainfall is high, pieces of forest get flooded. Once i saw this little beech in the water, trying to survive under these harsh conditions. I returned sometimes to this place to take pictures. One evening all the conditions were satisfactory.

This image was taken last summer on Skomer Island, Wales. It is well known for its wildlife, the puffin colony is one of the largest in U.K.The photo shows a detail or study of an Atlantic puffin resting peacefully under the rain. As Skomer is inhabited, puffins do not feel afraid of humans, and so people can be close to puffins and the photographer can think about the right composition and take this kind of intimate portraits. Also that morning the conditions came together: rain and light.

I captured this image during the migration of the sardines along the wild coast of South Africa. Natural predation, sardines are preyed upon by cape gannet birds and common dolphins. The hunt begins with common dolphins that have developed special hunting techniques. With remarkable eyesight, the gannets follow the dolphins before diving in a free fall from 30 to 40 meters high, piercing the surface of the water head first at a speed of 80km/h to get their fill of sardines.

A morning stroll into the blissful forest ! Ceaseless drizzles dampening the woods for 12 hours a day; The serene gloom which kept me guessing if it was a night or a day. Heavy fog, chilling breeze and the perennial silence could calm roaring sprits; And there I spotted this 20cm beauty the Green vine snake ! I wondered if i needed more reasons to capture this with the habitat; For I was blessed to see this at the place I was at. I immediately switched from the macro to the wide angle lens.

An EF2 tornado bears down on a home in Wray, Colorado- May 7, 2016. As soon as we were safe, as the tornado roared off into the distance through a field before roping out, we scrambled up the hill to check on the residents.Thankfully, everyone was alright, and we were grateful for that. As I was checking in with a young woman coming out of the basement, we became very aware of a strong new circulation - right above our heads. We needed to run for cover, and did so before saying a proper goodbye.

A remarkable conservation success story, the graceful Great Egret was saved from the brink of disappearance in Hungary, when in 1921 there were only 31 mating pairs remaining. Less than a century later, international conservation efforts have triumphed. We can now count over 3,000 mating pairs in Hungary alone.

Green turtles devour the soft tentacles of a jellyfish which are a common food source for many turtles.

'Friendship knows no color, nationality, race and social level, friendship knows no age and gender, friendship knows no distance' -quoted by Luis A Ribeiro Branco-. This way must be. And this images perfectly could represent that message. Two Empusa Pennata which seem to play a game on the thin plant. Wildlife image and absolutely uncommon to see a couple of this species together.

The Crow saw the Puffy Owl resting and decided to chase away the Owl from its territory.

These polar bear remains have been discovered at one of the islands of Northern Svalbard. Unfortunately we do not know definitely whether the bear died from starving or aging, but more likely if we see the good teeth status - from starving . They say nowadays such remains to be founded very often - global warming and ice situation influence the polar bear population a lot.
