What do moose eat in the winter?

Visitors to the Greater Yellowstone often look at the vast sagebrush and wonder what purpose it serves...other than catching your feet and tripping you on every step. Actually, this ecological community supports a remarkable diversity of wildlife. For example, sage brush flats provide critical winter habitat for moose. Such as the bull moose pictured here browsing on bitterbrush.

Ermine

Catching a glimpse of these little guys is always a treat...one that never lasts long. This is an ermine. Their coat turns from brown to white each winter, allowing them to be nearly invisible as they move through a snow white landscape. Their tail has a black tip on the end, which functions as a decoy luring any potential predators to strike there, rather than a more vulnerable part of the body.

Bull Bison in Grand Teton

This may be my favorite thing to see in the winter...a big bull bison covered in frost. The winter coat of a bison is so well insulating that there isn’t enough heat escaping their body to melt the frost. I’ve been able to photograph this bull several times over the last couple years. His exceptionally red coat, and the red patch on his face, make him easily recognizable.

Red Fox in Grand Teton

There are few things I find more visually striking than a red fox against the white snow. I found this fox as it was hunting for rodents under the snow. The fox will listen carefully for movement under the snow, turning its head back and forth to pin point the sound before leaping into the air and diving head first into the snow.

In Search of Great Grey Owls

     It has been a challenging year for Great Grey Owls in the Tetons. With such a heavy snowfall, and repetitive thawing and freezing cycles, the snow pack was near impenetrable for these skilled hunters. Quite a few succumbed to the harsh conditions and were found dead. The ones that survived, managed to do just barely that, and did not have the strength to nest and raise chicks.

     On a typical year I spend a lot of my time with these owls. So much so that is easy to take it for granted. My search, going on three months, for just one good Great Grey image has really made me appreciate the time I’ve had with them in the past.

     After hearing about the appearance of one in the backcountry the other day, I dropped everything to investigate it. It took several hours of hiking, but just as the sun dropped behind the mountains I found the “Phantom of the North” hunting in an aspen grove. My time with her was brief, as darkness was enveloping the forest I still had to trek through to get back to the car, but I was reminded why I spend an inordinate amount of timing searching for just a moment with these birds.

Perseid Meteor Shower in Grand Teton National Park

Hopefully you were able to experience this year's Perseid Meteor shower. I missed it the last two years, so I decided this was the time to make up for it. I stayed out all night for two nights in a row photographing the shooting stars reflecting in alpine lakes and soaring over the Teton mountain range. The image featured below was one of my favorites. Between 4:30 am and 5:00 am the sun, while still far from breaking the horizon, began to lighten the sky and the mountain tops. In this thirty minute window the meteors, as if to take advantage of their last opportunity to appear against the darkness, began rapidly flashing in the sky every few seconds. The image below is a combination of several consecutive exposures to give a sense of what this scene felt like.
