Mountain Goats in Wyoming

“Mountain goats. Beartooth Plateau, Wyoming," writes Jay Anderson in sharing these three photos with us. "Part of the greater Yellowstone ecosystem.” These amazingly sure-footed climbers and leapers (able to soar up to 12 feet in a single bound) are not actually goats; they're part of a family that includes gazelles and antelopes. They're able to maneuver on steep slopes in part because their cloven hooves have inner gripping pads and sharp, curved, anti-slipping dewclaws and can be spread apart for traction. The age of a mountain goat can be determined by counting the growth rings on their horns, which they don't shed. Many thanks to Jay for his photos. Have you ever seen or photographed a mountain goat?

The Unseen Gray Tree Frog

“I accidentally put my hand on this gray tree frog while hiking over lichen-covered granite boulders at Borestone Mountain Audubon Sanctuary in Guilford, Maine," writes Jill Osgood in sharing her photo with us. "The cold slimy frog under my hand made me scream, but the frog seemed unfazed. Truly amazing camouflage!”

In addition to having those lichen-like blotches to hide them, Eastern gray tree frogs can change color to match their surroundings; their scientific name is, appropriately enough, Hyla versicolor. Thanks, Jill. Anyone else encountered a tree frog or other animal so well camouflaged that you've nearly missed it?
