A few days ago I went to see this pale beauty! Its been on my “owl bucket list” for a long time. Especially gratifying since I searched three times for the subarctic at Springbrook Nature Center in Fridley, Minnesota a few years ago.

After a 4 hour drive from our homestead on the Wisconsin border of Minnesota, I arrived on the complete opposite side of the state on the North Dakota border. I had just about an hour before the sun set.

A wildlife photography friend had tipped me off to the location of this stunner. It had been seen on and off for a couple months. But as I began searching the numbers trees in the woods along the Red River of the North I started wondering if I would really find it.

But then there it was! On a tree I thought I had looked at on my way in. Wow! What a pale beauty! The Subarctic (or Western Taiga) subspecies of Great Horned Owl is very pale or even white with black markings. But the disc around the eyes almost always shows some color. They can be mistaken for Snowy Owls if it weren’t for this trait (and of course their feather “horns” which on Snowies are tiny and usually hidden).

This boreal subspecies occasionally may mate and nest in northwestern Minnesota. This bird appeared to be a male since it seemed smaller in size. Females are significantly larger than males.

Thanks again to Matt Sorum who found this in Clay County a couple months ago!

Video shows it coughing up a pellet, stretching, fluffing, watching a couple woodpeckers and silhouetted against the full moon.

Has it been a tough winter in Minnesota? Ja, sure ya betcha! Up near Lake Superior we had 84 days that were below zero, Eleven feet of snow, Minus 50 degree windchills, a couple days of minus 40 air temps, and snow on the ground until Mid May. In fact, when we left from Wrenshall on May 11, I still had snow in my ravine! So what’s a little more winter in Yellowstone? Temps ranged from 22 degrees to around 60 degrees, but there was still much residual snow from winter in the Hayden Valley. The Lamar Valley was snow free. It all depended on your elevation.

Twelve-foot high snow banks greeted us in several passes in the Hayden Valley on May 12th! I’m jumping as high as I can and nowhere near the top.

Is there a more beautiful blue in Nature? The Mountain Bluebird actually seems to glow when seen in the right light. Though not technically iridescent, the blue color is created by tiny air pockets in the barbs of feathers which scatter incoming light. So we are seeing reflected light, not blue pigment in the feathers. [Canon 7D with Canon 400mm f5.6 lens, f5.6 at 1/1250, braced on car window frame]

Sandhill Cranes nest in the Park. We found this guy between Mammoth and Norris. I like how the S-curve of his neck matches the curving stream. [Canon 7D with Canon 400mm f5.6 lens, f6.3 at 1/6400 (not sure why I had such a high ISO…A mistake for sure), braced on car window frame]

Juvenile Yellow-bellied Marmot. Adorable!

The three above are the very personable Yellow-bellied Marmot (Marmota flaviventris), a mountain-dwelling rodent that lives in talus slopes and boulder fields of the western U.S. The closest they get to Minnesota is the Black Hills of South Dakota. Their cousin the Hoary Marmot is found in British Columbia and Washington state (Marmota caligota).

Marmots have a “harem-polygynous” mating system in which the male defends two or three mates at the same time. They hibernate from September to May, which explains why we never see them on our fall trips in late September or early October. They are omnivorous but eat mainly plant material supplementing with grasshoppers, bird’s eggs, etc. Each colony is 10-20 individuals. Marmots can live to 15 years! When alarmed they give a high-pitched whistle, which is how they got their nickname..”Whistle Pig.”

We found out that there is a Great Horned Owl nest near the natural history museum/visitor center at Mammoth…and it has been there for years. We just stumbled upon it when we saw a photographer shooting something and went to investigate. A Black-billed Magpie was mercilessly harassing the owl…from only a foot away! (I got some video).

Male Pronghorn just sitting around chewing its cud…literally. When I watched my video of this buck, you can see the wave in his neck as he regurgitates food into his mouth to chew again. [Canon 7D with Canon 400mm f5.6 lens, f7.1 at 1/160, tripod]

It usually pays to stay out in the field until the sun goes down. We found this Coyote hunting the Hayden Valley sagebrush flats in golden light. He came quite close to me as this shot is barely cropped! [Canon 7D with Canon 400mm f5.6 lens, f5.6 at 1/2000, Handheld]

He made some magnificent leaps in order to break through the crusty snow to get at small rodents but all were too far away for good photos…but I did get some video and this HIGHLY cropped image.
