WILDLIFE SELF PORTRAITS

41-21-12

Wary of leaving the security of the Slana River, an adult beaver slowly approaches a scent mound.  Interrupting an invisible beam, the beaver triggers a digital camera to capture this self portrait.

BEAVER BEHAVIOR

41-21-1Hauling armloads of mud and moss, beavers continually add to their mounds and frequently add a fresh scent.   Bulletin boards for beavers, scent mounds are important features of their territory. And a good place to set up a camera trap I thought.  You know,  just to see what might pass. Kind of a wildlife selfie station. I pick the place, they pick the time.

Once or twice a month this wandering lynx passed the lens.

Over the spring/summer months the camera had several views of this scent mound.  To the beavers the camera was part of the scenery. I had nightmares of them chewing on the camera or even pulling the whole camtraption into the river.  But they completely  ignored it. Beavers sometimes used the mound as a feeding platform or to just sit and chill for a few minutes.  A late night surprise, the south end of a northbound grizzly. (below)

ak-21-12After a couple weeks of rainy weather I arrive at the camera station with a dry Nikon.  The set-up is prone to problems. False triggers, battery failure, flash and sensor failure due to moisture, even snowshoe hares chewing cords. The beavers were busy refurbishing an old bare-bones lodge downstream and had all but stopped coming to the scent mound. But I kept the camera station operating. I like unexpected surprises.

NORTHERN GOSHAWK

 

HUNTING IN WINTER

533-19-8From a perch in a stand of stunted black spruce, a well camouflaged immature northern goshawk stalks its prey.   Their short, wide wings and long tail give it both speed and manoeuverability to pursue prey in the forest. No small bird or mammal is safe from a sudden ambush, but this winter the large accipiters  key on snowshoe hares.

28-19-5The snowshoe hare has perfected the art of camouflage, but as an extra defense against the  goshawks, they often use snow burrows.  But the snowshoe hares’ best defense against the sudden attacks by goshawks is its nocturnal behavior.

533-19-3As I photographed a snowshoe hare this immature northern goshawk suddenly appeared out of the blue shadows and killed my photo subject.  She mantles her prey with powerful wings.

533-19-9Often northern goshawks show little fear of humans.  When I approached it flew a few yards away but quickly returned to its prey.  The goshawk fed for nearly an hour leaving only the feet, fur, guts, head and large bones.

28-19-6While the snowshoe hare population is near its peak this year, their primary predators populations (northern goshawk, lynx, coyote and great horned owl) are also peaking.  And this heavy predation will inevitably cause the next snowshoe hare population crash.

ALONE WITH THE NORTHERN GOSHAWK

GOS_011For months, over two nesting seasons I spent nearly every day in the company of northern goshawks.  Slowly they would reveal their secret lives.

GOS-012

After the chicks hatch,  northern goshawks become very aggressive at their nests.  By visiting the nesting territory on a daily basis, starting early in the nesting season I seemed to have gained the trust of the goshawks.  By building my blind near their nest under the cover of darkness, wearing the same clothes everyday and never disturbing the nest, I was able to climb into my photo blind or walk around the forest below unmolested.

 

SQUIRREL SMARTS

The great female goshawk rose up from her eggs and stepped to the edge of her three-foot wide nest.  Eyes of blood locked onto her target.  Diving headfirst off the nest, she pumped her wings quickly accelerating to attack speed.  Long tail feathers flared and pivot, sending the goshawk speeding around the base of a large douglas fir and crashing into the understory.  Squealing in terror, a red squirrel jumped to the trunk and instinctively darted to the opposite side, sticking like velcro to the rough, dry bark, then squirrel shot up the trunk into the canopy.  Again the goshawk attacked.  Going up, the squirrel was faster but  on the way back down the goshawk closed the distance.

Among the thick branches of the canopy the squirrel had the edge, but not by much.  Using feet, bill and wings, the goshawk literally swam through the boughs.  Desperate to lose the hawk, the squirrel spiraled up the nest tree and right over those precious eggs, before jumping to an  adjacent tree.  The squirrel somehow missed being snagged by those talons, utilizing unearthly tricks of speed and anti-gravity.  I could keep track of the chase through the various observation and lens slits cut into the photo blind, but the action was much too quick and hard to follow so I missed getting any photos.  It was inevitable I guess, when I felt the squirrel coming up my blind tree, the gos riding his wind.  A vision of the squirrel taking refuge up my pant leg was suddenly a painful possibility.  Just as the squirrel shot inside the blind I yelled and smacked the side of the blind.  Luck was cheap that June morning.  After a couple of quick laps around the legs of me and my tripod, the squirrel dashed back out and jumped to the next tree about five feet away.

533-268-2Slamming through the branches with little regard for its plumage, the gos didn’t let up.  But the squirrel had a little luck of his own stashed away.  Running headfirst down the trunk, the squirrel made an Olympic jump 25 feet from the ground.  Bouncing off the forest floor the squirrel made for thicker scenery.  After orbiting several more big trees and an amazing sling-shot the squirrel made it to a thick jungle of downfall.  For the next 30 minutes, the goshawk perched 20 feet below her nest and preened.  The squirrel barked, chattered and buzzed and told the world what he thought of goshawks nesting in his five acres.

533-163-1Three weeks earlier, the goshawk had calmly sat on her eggs while this same squirrel climbed the nest tree, dug into the bottom of the nest to find and nibble on mushrooms.  I guess it seemed like the perfect place to dry mushrooms.

 

 

 

NORTHLAND NIGHTS, NORTHERN LIGHTS

star trails-13-3Relaxing in the wood fired Snorkel hot tub.

After supper, I built a fire in the hot tub.  Overnight the temperature had dropped to about fifteen below zero F. and the temperature in the hot tub was down to about seventy degrees F.  It takes about two hours to get the hot tub temperature back to one hundred degrees.  Cindy and I jumped in and watched the stars and the occasional meteor streak overhead.  An hour later we climbed out and got dressed in the nearby sauna, also heated with a wood stove.

I noticed a green glow of aurora borealis in the north and decided to take out a camera.  I set the tripod and camera on the ice of Rufus Creek.  The camera was set on interval timer to record a photo every ten seconds that I could later turn into a video.  Returning to the house I told Cindy the aurora was really going for it so she got dressed for the cold and we went outside.  I took along another camera and set it to record the aurora dancing over the house.  We watched as the aurora went crazy.  But it was getting chilly so I suggested we walk out to the hot tub and check the temp.  I slide the lid over and the thermometer read 106 F.  A bit on the warm side but tolerable so we stripped down and jumped in.  And for the next hour we relaxed in luxury and soaked it all in.

SNOWSHOE HARES

 

DSC9993In early March, snowshoe hare (Lepus americanus) tracks began to appear where none had been all winter long. I guess the solitary males are out and about looking for females. The snowshoe hare cycle has been on the upswing for a couple of years but the hares are still uncommon in most of the black spruce forests around our place on the northern edge of Wrangell/St. Elias National Park. High quality hare habitat, mixed forests with willow and alder thickets are the nucleus of hare populations and often the only places where hares are common during low-cycle years . These “bunny patches” are where snowshoe hares multiply and disperse.  A rising (or falling) hare population has a big impact on most predators and their prey.  With snowshoe hare populations locally low, their main predators, lynx, red fox, northern goshawks, great horned owls and even northern hawk owls are low as well.  Low numbers of predators has relieved pressure on prey species such as spruce grouse and snowshoes allowing them to recover.  Grouse populations have the ability to rebound rather quickly as we have seen them do locally.  All these cycles are driven to a large degree by the rise and fall of snowshoe hares.

THE MARTEN

49-20-5The marten scrapes out a tough living in the northern forests.  The largely nocturnal members of the weasel family, prey on small birds and mammals.

49-37-2A tireless traveler, the marten (Martes americana) leaves an endless line of tracks through the Alaskan wilderness.  Like other members of the weasel family, martens successfully hunt quick prey like the red squirrel and snowshoe hare in deep snow. Tracks are the most common sign of the presence of martens.  Following or backtracking marten tracks will tell a story of what this tough, little predator has been up to and gives clues to their habits. Though they are seldom very common, martens are not endangered over most of their range.  But martens are so shy and secretive that little is known about their mysterious lives.   Old growth  forests with large trees and numerous standing and fallen dead trees are a martens prefered habitat, providing cover, food, shelter and cavities for their dens.

SONG OF THE BOREAL

 

aaa

For the past six weeks or so we have been delighted by the nocturnal trilling song of a little boreal owl.   I believe the male has claimed our little forested yard as his own.  He sings almost every night from one of the old northern flicker cavities in the black spruce stand surrounding our home.  With his little round head filling up the hole he serenades the darkness, or sometimes accompanies the glow and flicker of the aurora.

PHOTOGRAPHING AURORA BOREALIS

aurora borealis-15-50Aurora borealis in my back yard.  Slana, Alaska

The aurora borealis displays are really picking up this year.  After a few years of slow aurora activity its an exciting change and a great excuse for stay up late and snapping a few photographs.  With todays wonderful digital cameras getting great aurora photos is easier than ever.  I remember the day when I had only Kodachrome film with an ASA speed of either 25 or 64.  Living in Alaska it could take more than two weeks just to get your processed film returned and check your results.  Today you can snap a shot or two check the exposure using  your histogram display, adjust your exposure if necessary and shoot away .  You can be confident of what you’re getting.

OWLS BY DAY, OWLS BY NIGHT

BY DAY

DSC_1262Adult male northern hawk owl is active during the day.

For a few weeks I have been photographing a pair of northern hawk owls that have nested in a stand of tall white spruce.  Hawk owl populations are cyclic and for the past three years they have been rare in my part Alaskan interior.  Over the past twenty years, I have been trying to capture their little known life history.  In those twenty years I have found only six or seven active nests.  Continue reading
