Video by @ronan_donovan // Seasonal change is one of my favorite parts about living in the north. The winter is a great equalizer in the natural system. The frozen Yellowstone River becomes a torrent in spring as the high elevation snowpack melts, nourishing the landscape below. Hop on over to @ronan_donovan for some sounds of spring. #montana #picoftheday #nature

Also, why is this species a ‘good news story’? #followme on @paulnicklen to learn more about this great species. #whale #nature #naturelovers #hangone #photooftheday #picoftheday
Photo by @daviddoubilet // Table corals compete for space on Sno Reef on the Great Barrier Reef. This is a picture of a healthy robust Great Barrier Reef but today the worlds largest coral reef is literally in hot water and struggling to survive. Rising temperatures are causing coral bleaching, a process that occurs when thermal stress causes the coral polyp to lose its algae that provides its color and supplemental nutrients. Sequential back to back bleaching events in 2016 and 2017 have affected nearly 900 miles of the reef giving the reef little time to recover.

Photo by @cookjenshel On Arbor Day we need to recognize the important role that trees play keeping our planet healthy. During one year, a mature tree will absorb more than 48 pounds of carbon dioxide from the atmosphere and release oxygen in exchange. In this era of human induced climate change we need them more than ever. @natgeocreative @thephotosociety #ArborDay #WiseTrees #climatechange #planttrees #savenature #trees
Video by @Renan_Ozturk @coryrichards // It's Everest season! Here is a jovial photo-booth portrait sequence of Sherpas and other Nepali high altitude workers (and western volunteers) who help deliver climbers to the summit each year. Shot during a session of the @khumbuclimbingcenter - This program conducted each year in the offseason helps educate these brave workers to do their jobs more safely and also embraced the positive spirit of climbing! @conrad_anker @mreverest7x @jenniloweanker
Video by @tbfrost | Oceanic white tip sharks , one of the most endangered - filmed off Cat island in the Bahamas just 3 days ago. Photographer and conservationist Hussain Aga Khan is seen here photographing the sharks as part of his efforts to help protect the ocean - and sharks - through his conservation fund : @fonassociation To see more video of this amazing dive and to see a video where one of these curious sharks swims right next to me, follow @tbfrost
Photo by @argonautphoto (Aaron Huey). A #Leopard tries dragging an Impala higher up her tree as another Leopard approaches below. #MoremiGameReserve, #Botswana. The red light is used because it causes much less stress than a white spot light. She was later able to get the Impala to a higher branch but almost dropped it on this attempt! Can you imagine carrying something close to your own weight by your teeth while climbing a tree!?
Photo by @CristinaMittermeier // Sailing on silver seas after the massive storm that hit our ship with 60-knot winds and 8-meter seas for 5 days finally cleared. Our crew was delighted by the exhilarating speed and acrobatic turns of a pod of Peal’s dolphins that accompanied our expedition vessel for several hours as we began crossing the Drake passage on our way back to the Falklands. On #Assignment for @NatGeo, @NatGeoPristineSeas and @Sea_Legacy with @PaulNicklen, @Ladzinski, @Andy_Mann and @CraigWelch. Grateful for the opportunity to shoot on this important story.

Image by @joelsartore | A critically endangered red ruffed lemur at the @millerparkzoo. These lemurs are very clean and spend a large amount of time grooming themselves with their specialized incisor teeth, hind claws, and tongues- which are colored black. They live in matriarchal groups and forage for food together during the abundant wet season. Unlike most lemurs, red ruffed lemurs will often divide and find food on their own during the dry season. Red ruffed lemurs live in a very small range in the forests of northern Madagascar and are threatened by the huge surge of illegal rosewood logging that began after an undemocratic change in political power in the area in 2009. These lemurs are also threatened by hunting, burning of habitat, the illegal pet trade, and frequent cyclones.

Video by @salvarezphoto (Stephen Alvarez) As a photographer one of the things I practice is noticing small things, details. Occasionally it pays off in unexpected ways and I sometimes see the strangest things. I often photograph red efts that I see in the forest. They are the juvenile form of the Eastern newt (Notophthalmus viridescens). But I had never seen this before. A bright green caterpillar crossing the newt like a bridge. Funniest thing was that the newt waited patiently for the insect to cross before moving on. There is a whole wild world on the forest floor. #forestunseen #home #redeft
Video by @Filipe_DeAndrade @brianmoghari and @mckenziebarney | While they’re excellent natural pollinators and extremely beneficial to their environment, the ruby-throated hummingbird makes it quite a challenge to get a great shot. But it’s a fun challenge. For this adventure we wanted to film them on their migratory path back to Central America for the winter. We knew that at that point on their migration they would be extra aggressive and territorial over food sources since they have to travel over 500 miles without stopping. There was a lot of coffee and a lot of nectar drank on this shoot. Check out the entire sequence in my series #WildUntamed on natgeowild.com/untamed or click the link in my personal bio.
