  • The Gaboon Bush Viper (Bits Gabonica) is a beautiful and fascinating venomous snake found in East Africa. Its massive head compared to other vipers is very iconic and important as it allows this viper to have the longest fangs of any viper on the planet (up to two inches in length). Snakes are vital to the ecosystems they inhabit. They deserve your respect more then your fear. Don't kill snakes! Be sure to swipe to the left to see the behind the scenes photo of this amazing encounter!

  • The Resplendent Quetzal is one of the most beautiful birds on the planet. I spent the last few days photographing multiple nesting pairs of Quetzals in the Cloud Forests of Costa Rica. Taken with my Sony a1 II w/ the 300mm f/2.8 GM lens #birdsofinstagram #birdsphotography #birdlovers #birdphotography #sonyalpha #sonyambassador
  • It is nearly impossible not to fall in love with Patagonia once you have experienced it. The weather can certainly be rough, but the light at the end of the tunnel is often spectacular when the weather ends up cooperating. Sony a1 w/ 24-70 f/2.8 GM II #sonyalpha #sonyambassador
  • The Patagonian mountain range of the Southern Andes is easily one of the most beautiful and awe inspiring destinations on the planet. Torres del Paine National Park in particular is beyond incredible! Sony a7R V w/ 70-200 f/2.8 GM II #sonyalpha #sonyambassador #igreels #reelsinstagram #reelitfeelit #landscapephotography
  • The Bengal Tiger is the most beautiful big cat in the world. There is something so special and different about them when compared to lions, leopards or jaguars. Have you seen one in the wild before? Sony a1 II w/ 300mm f/2.8GM or 600mm f/4 GM #sonyalpha #sonyambassador #wildlifephotography #indiawildlife
  • Smartphones are pretty powerful these days but there is no substitute for having the right camera gear with you when on Safari... especially when you come across an incredible 🐆 in the wild! Sony a1 w/600mm f/4 GM #sonyalpha #sonyambassador #wildlifephotography #leopard
  • It is almost Quetzal season down in Costa Rica! What a truly amazing bird! Sony a9 II / 400mm f/2.8 GM w/ 2x TC
  • The Cheetah is such a fascinating creature! There is something truly special about seeing one in the wild while it is in its element. These predators are undoubtedly built for both speed and lethality! Swipe to the left to see the full image! Have you ever seen one in the wild? Sony a9 III w/ 600mm f/4 GM #sonyambassador #sonyalpha #wildlifephotography #wildlifeplanet
  • Yesterday, a new volcanic eruption opened up in the Keflavik Peninsula in Iceland. What better time is there to revisit one of my favorite eruptions in the region in recent history? These were all shot in the summer of 2021, when the world was in awe of just how close you could get to the incredible natural phenomenon! Have you seen a volcanic eruption in Iceland before? If so, which one? #volcanoeruption #volcanoes #djimavicpro
