A radio-collared wolf pauses to survey her surroundings before plowing through the deep snow. While looking ahead she used one ear to listen for members of the pack following behind as they co-ordinated their movements up a hill in search of prey.

When not using his antlers to fight over breeding rights, this elk delicately used his antlers to scratch a hard to reach spot!
The dipper gets the distinction of being the only aquatic passerine (songbird) in North America. Remarkably, it makes its living diving and swimming in frigid glacier fed waters and then flies around in temperatures as low as -40 degrees. Adaptations that allow this bird to survive include an extra layer of feathering, an enlarged preen (oil secreting) gland for waterproofing, a nictitating membrane (third eyelid), enlarged muscles of the eye to accommodate for underwater vision, nasal flaps and increased hemoglobin levels to boost their blood oxygen carrying capacity that is essential for underwater swimming for up to 30 seconds at a time! I spotted this one along a partially frozen river as it entered a small ice cave in search of food.
One more for today. This lamb of the year watched me from a comfortable distance on a snow covered mountain near Destruction Bay, Yukon. The herd blended in so well with the snow it was hard to spot them initially. I wanted to mimic this in my photo so I overexposed more than typical to create this effect.
In a co-ordinated burst, a flock of snow buntings cascades from a tree to fly off in search of food.

Last weekend I came across a peculiar scene with this bald eagle literally swimming across an icy cold river using its wings as oars. Up in the sky the distinctive call of ravens could be heard as they circled. The eagle managed to make its way to shore, climbed up a bank and rested in the snow. After several minutes it attempted to fly off but was unable to get any lift. It did this a few more times but still couldn’t get off the ground. Thinking that it had fractured one of its wings, I put my gear down and hiked into the forest to try to keep out of its sight while I approached it. I got to within about 30 feet before I ran out of any tree cover. By then the eagle had spotted me and I made a dash for it (don’t worry, I’m a trained professional and I have handled many birds of prey!). It quickly beat its wings and ran through the snow as fast as it could. Just as I was getting close enough to grab it, it managed to get out onto an ice-flow that would not support my weight. It seemed to know this because it turned and watched me as I came to a halt. Thinking that it might come back onto more stable land, I headed back into the forest to wait. About thirty minutes later, I moved into a better vantage point but it must have caught sight of me. With its powerful legs it sprang up into the air and managed to get just enough lift to take off. Thankfully, it cleared the river, flew several hundred feet and managed to perch in a nearby tree!
While I didn’t see the initial incident it is highly likely that the ravens managed to ground the eagle in the river. Once there, it became waterlogged. By resting in the powdered snow, some of the water was absorbed while the rest turned to ice. By repeatedly trying to take off, the ice crystals on the tips of the feathers would have been knocked off, which must have been just enough for it to regain flight. Thankfully no broken bones, but likely a bruised ego and a new respect for ravens! I on the other hand learned that eagles can swim and I have a new respect for their ability to tolerate frigid conditions and still survive!

From Little Red Riding Hood to present day, the wolf is often given an image that is not even close to factual. Hollywood continues to portray wolves as human killers (eg. the latest Jason Bourne film) and groups advocate for open hunting seasons because they feel the wolf is killing all their deer or free ranging livestock. On the other extreme are the advocates that think wolves can do no harm. As usual, somewhere in between these two extremes is where the wolf belongs. Here, one sits down in a field of daisies just long enough for me to snap off a few pictures before rejoining the pack.
