Northern Owls in a Hoar Frost Wonderland

When I left my house this morning (Dec 11th) I was a bit bummed as the skies were gray and the light flat. But when we started gaining elevation out of Duluth, a hoar frost wonderland began to appear. Every single bud, branch, needle and twig on every single tree was coated in a feathery frost. Spectacular! Now if we could only find some subjects! I was traveling with Dave Shaffer from Spooner, Wisconsin (one of the best Black Bear photographers in the country…see his images (all taken in the wild) at http://www.bearwitnessimages.com) and we were after one thing…Owls!

Most birders and photographers who love boreal birds have heard of northern Minnesota’s Sax-Zim Bog. It is a Mecca for those searching out lifers or photos of northern birds such as Boreal Chickadee, Black-backed Woodpecker, Sharp-tailed Grouse, Ruffed Grouse, Pine Grosbeak, White-winged Crossbill, Evening Grosbeak, Common Redpoll, Hoary Redpoll and, of course, owls. Great Gray Owl and Northern Hawk Owl are regular nesters and can be found easily most winters. Boreal Owls, Snowy Owls and Northern Saw-whet Owl are much more rare.

After a couple hours of unfruitful searching, we spotted a dark blob far down the road. I knew instantly that it was a Great Gray…the Phantom of the North! This was Dave’s first ever Great Gray…a “lifer” in birder parlance. And what a bird! This guy (girl?) kept on hunting for over an hour as we watched and kept clicking the shutter.

This is probably my favorite image from the day. I lover the graceful curve of the Tamarack tip and the “bird in landscape” feel. It really gives you a sense of the boreal haunts of this magnificent bird. I tweaked the white balance to give it a more cool (blue) feel. Though these are the tallest owl in North America (30 inches tall!) they are all feathers and rank third in weight (behind Snowy and Great Horned).

Hoar frost Tamaracks Sax-Zim Bog MN IMG_1986Hoar Frost is relatively rare in the North Woods, but when it happens you better grab your camera and go! Here is a definition from http://www.weatheronline.com.uk
“Under clear frosty nights in winter soft ice crystals might form on vegetation or any object that has been chilled below freezing point by radiation cooling. This deposit of ice crystals is known as hoar-frost and may sometimes be so thick that it might look like snow. The interlocking ice crystals become attached to branches of trees, leafs, hedgerows and grass blades and are one of the most prominent features of a typical ‘winter wonderland’ day. However, the fine ‘feathers’, ‘needles’ and ‘spines’ might also be found on any other object that is exposed to supersaturated air below freezing temperature.

The relative humidity in supersaturated air is greater then 100% and the formation of hoar frost is similar to the formation of dew with the difference that the temperature of the object on which the hoar frost forms is well below 0°C, whereas this is not the case with dew. Hoar frost crystals often form intitially on the tips of plants or other objects.”

Great Grays are powered by voles—both Meadow Vole and Red-backed Vole. Some studies have shown that their diet is 97% voles. Their talons are tiny compared to Great Horneds which eat much larger prey (rabbits, squirrels). And voles must be in good supply as this guy caught two back to back within minutes.

At dusk we found another Great Gray along McDavitt Road, about a mile or two from the other bird (as the raven flies). Thankfully Great Grays often pick photogenic perches in this stretch of road that has NO power poles or fence posts!

10 Reasons NOT to Take Fall Leaf Photos

This fall’s color has been one of the most spectacular in recent memory…It is not every year that the oaks, aspens and maples all peak at the same time, but this year they are. So what’s your excuse for not getting out and shooting? Here are some of the reasons I find myself hmmming and hawwwing and procrastinating and avoiding taking fall foliage photos.

1. I CAN’T FIND A GOOD COMPOSITION
SOLUTION: Make your own! I found this dewy Quaking Aspen leaf and very carefully placed it on a background of reversed maple leaves that I laid out. I love the contrast of the yellow with the magenta.

2. IT’S CLOUDY OUT
SOLUTION: No problem, cloudy and foggy days are the best for recording the saturated colors of fall. Even rainy days can be great. But remember to use a polarizer to reduce the sheen from wet leaves.

3. THE LEAVES HAVE ALREADY FALLEN
SOLUTION: So what?…The leaves can be just as pretty and colorful on the ground.

4. I WORK DURING THE DAY
SOLUTION: Get out early! Frost on fall leaves can be a dramatic element

5. TOO LATE…SNOW HAS ALREADY FALLEN
SOLUTION: Count your lucky stars because this is a rare event. Get out right away and find some colorful leaves dusted with snow to make a stunning shot.

6. IT’S JUST A JUMBLE OF LEAVES, TREES, AND COLOR OUT THERE…I CAN’T FIND A SUBJECT
SOLUTION: Isolate! Find a clump of particularly beautiful leaves…or an individual fallen leaf…or grab the telephoto lens to highlight one area of color.

7. THE LEAVES WON’T STAY STILL
SOLUTION: Use this to your advantage…If leaves are swirling in an eddy of a river or creek, just set your tripod up and shoot at a very slow shutter speed…Slower the better. The leaves will become a swirl of color but the rocks and shoreline will be sharp.

8. I CAN’T FIND ANY COLORFUL LEAVES
SOLUTION: Shoot brown leaves

9. I ONLY BROUGHT MY WIDE ANGLE LENS
SOLUTION: The best lens is the one you have with you…So use it! But you have to be careful with wide angle fall foliage shots that you don’t include too much of a gray sky. Here I intentionally eliminated the sky to focus on the variety of colors in a wooded meadow.

10. I ONLY BROUGHT MY TELEPHOTO LENS
SOLUTION: Perfect…Much easier to find good compositions with a medium telephoto (70-200mm) than with a wide angle lens, I believe. Head to a vantage point or lookout where you can isolate part of the scene like in this image from Oberg Mountain, Minnesota, Lake Superior North Shore.

There you have it…A bunch of reasons NOT to shoot this fall’s gorgeous leaves…And a bunch of solutions to these common excuses. Now let’s get out there and shoot like crazy before all the leaves are gone!

Hard Frost

I was up with the baby at 5am…As I was rocking him back to sleep, I saw the temperature was hovering around freezing and the sky was clear. I knew the temp would fall a couple more degrees at or near sunrise, often the coldest time of day. Frost forms when the air temp around the leaf is below the dew point; moisture condenses out of the air onto the leaf and then crystallizes into ice. Conditions in early autumn are often ideal for frost formation; Cold, calm, clear nights in an atmosphere loaded with moisture. Winter is often too dry.

I headed over to the Wrenshall WMA where I knew a field of goldenrods and dogwoods would be a good place to find frosty subjects. A red dogwood leaf rimmed in frost first caught my eye. I intentionally chose a shaded background to contrast with the white fringe of ice.

My real goal, though, was to find an orbweaver spider web that had frosted over. I have a running “battle” with my friend and fellow author Larry Weber about finding and photograph a frosted orbweaver web. He technically won last year when he found an old tattered web that had frosted. But the one I found today was 80% perfect. Larry is in the Adirondacks so I’ll have to rub it in when he gets back!

Yes, mine is on a barbed wire fence but I kind of like the juxtaposition of permanent hard and cold metal with the impermanent delicate fragility of a spider web. Ironically, both are meant to capture and contain…One insect prey and the other cows!
