No matter how many red fox I come across in my travels, I always get excited when I see one. Such elegant creatures. This one was spotted at Silver Salmon Creek in Lake Clark National Park in Alaska.

This was one of the four bull moose that I saw vying for a single female last fall in Alaska during the yearly rut. Chugach State Park, just outside of Anchorage.

Earlier in the week I posted a wide shot of a coastal brown bear hunting silver salmon at Lake Clark National Park in Alaska. Here’s a close up.

The Rocky Mountain elk has the largest antlers of all the elk subspecies in North America. In springtime and throughout the summer, the antlers continue to grow and are covered in velvet. Eventually, they’ll shed the velvet and then the antlers themselves. This guy had been sleeping in the grass and all I saw were those great big antlers until he woke up.

This bear has plans. Big plans. But he’s just going to think about them for awhile longer before taking action. Photographed at the Vince Shute Wildlife Sanctuary in Orr, Minnesota.

Just a common raccoon doing what raccoons do. This one was spotted in Key Biscayne, Florida creeping around a campground at the end of the day in search of scraps.

The American Marten, also known as the American Pine Marten, ranges throughout most of northern North America. They are in the weasel family of mustelids and about the same size as a mink. I photographed this one just outside of the northeast entrance to Yellowstone. I wish the background wasn’t a cut pile of wood, but I’ll take it as martens can be elusive and hard to spot despite their healthy numbers.
