LAST DANCE OF THE SOCKEYE

Leave a reply

Taking a peek into a tributary of the Copper River in Alaska’s interior reveals a rarely witnessed but prehistoric cycle of life.  Traveling nearly three hundred miles up the Copper River through a soup of glacial silt, sockeye salmon have reached their gravel spawning beds.

Since leaving the ocean and entering fresh water, sockeye salmon undergo dramatic changes.  Their silver skin turns to crimson red and their head becomes green. The male sockeye develops a wickedly hooked jawed, an aggressive attitude, and a one track mind to reproduce. Continue reading →

Adult, male Steller’s sea lion on the prowl in Prince William Sound.  Pink salmon, the most numerous of Alaska’s five species of salmon are schooling by the thousands just offshore.  The pink salmon returning to their freshwater spawning streams are dogged by a gauntlet of predators including, harbor seals, bald eagles, killer whales and sea otters as well as Steller’s sea lions.

HUNTING LIKE A HAWK

Leave a reply

DSC_2027A northern hawk owl perched atop a dead, black spruce overlooking its preferred hunting grounds, an Alaskan muskeg wetland.

The northern hawk owl is named after its hawk-like hunting behavior.  Like hawks, the hawk owl hunts by day using its keen eyesight to spot small birds and mammals.  The red-backed vole is by far the most important prey species. But the hawk owl is an opportunist and other species of voles and several species of shrews are also caught. During those years when snowshoe hares are plentiful, hawk owls will add these much larger prey species to their list, as will many species of birds from the tiny, common red-poll to birds up to the size of ptarmigan.

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 →

SEA OTTERS

On a recent trip to photograph humpback whales in Alaska coastal waters my plans were foiled because of bad weather.  High winds kept our small boat in the harbor.  But these same winds presented an unexpected photo opportunity.  Rough seas brought a couple dozen sea otters to a small protected bay for shelter from the storm.  At first the sea otters were shy and stayed out of reach of my telephoto lens.   But by hanging out in plain sight for hours each day they grew used my presence and would sometimes drift in close enough for photographs.

BACKYARD SAFARI PART 3

RED SQUIRREL

32-15-30I am still on my backyard safari.  This is where I do some of my favorite work.  I have had professional photographers scoff at the mere suggestion of doing in-depth work with such “insignificant” species as the red squirrels, voles and the like. But I happen to enjoy photographing all species of wildlife including red squirrels.  The idea of a backyard safari is to give one the incentive to compile a complete coverage of the wildlife in your immediate surroundings as well as gaining experience turning photographic potential into great photographs.

The red squirrel jumping straight on is a tough one.  I found a place where the squirrel routinely jumps form one branch to another.  The distance is just over three feet and it takes less than a second.  The problem lies in the tiny amount of depth of field with the 560 mm telephoto lens.  I use a Nikon 200-400 lens with a 1.4 tele-extender and pre-focus at about 4 meters.  There is less than one inch that will be in sharp focus.  I manage to get off about three frames each time the squirrel jumps and only about one in fifty photos will be in focus.  What that boils down to is about one photo every four days will be a keeper.  I could increase the percent of successful shots by adding a trigger which trips the shutter as the squirrel crosses a beam of infra-red light.  Maybe next week.

TRACKS

One of the few sets of snowshoe hare tracks I have seen in the backyard this winter.  They are currently at the low-end of their population cycle.

BOREAL OWL

The male boreal owl is still calling from the flicker holes but not every night.  I suspect he is also singing his territorial songs from other possible nesting sites in the area.

AURORA BOREALIS

Aurora borealis dancing over our little homestead

.All week I have been on  safari, backyard safari that is, trying to sniff out a few photographs. I continue working with the pine grosbeaks and red squirrels but they have proven tough subjects.  Yes even squirrels can be very challenging especially when you try for something new.  Last night a fantastic aurora show kept me busy for a few hours after midnight.  The unexpected beauty made up for those frustrating red squirrels.

For the past couple weeks a boreal owl has been singing after dark.  I had developed this situation by placing a couple of ladders within camera range of his singing posts.  He sings his territorial song while sitting at the entrance of a couple of old northern flicker nesting cavities.  On top of the ladders, I mounted ball heads so I could climb and place my telephoto lens and flash bracket quickly and quietly.  As I photographed the aurora borealis the boreal owl was singing from both of the flicker cavities.  During lulls in the aurora activity, I approached the cavities to see what was going on.  At one cavity there was no owl at the hole and I could hear the male singing from the other cavity.  Just for fun I scratched the tree trunk and to my surprise the head of a boreal owl emerged.  There were two boreal owls!  The male had attracted a mate.  That was exciting news.  Perhaps they would choose one of the cavities for their nest.

Ever feel like going on a safari but just can’t get away? Well, take a safari in your own back yard. Here you’re the expert. You know the terrain and what to expect.  And believe it or not everyone can benefit from this little exercise. In fact, even with the smallest back yard, some amazing and beautiful images can be made. I regularly take a backyard safari.

My Big Backyard
I bet my back yard is bigger and wilder than yours! Our ten acres of northern boreal forest borders Wrangell/St. Elias National Park, Alaska, our largest National Park. My back yard stretches south for a couple hundred miles through the wilderness of Alaska.  We have had grizzlies, wolves, red fox, lynx, great gray owls, nesting hawk owls, bald eagles, golden eagles, willow ptarmigan, great horned owls, sharp-tailed grouse, boreal owls, marten, caribou, Alaskan moose and much more on out little ten acre homestead. But still it is usually a difficult challenge to photograph the local wildlife .  Nothing comes easy.

Developing Photo Potential
Getting the most out of your backyard safari is the same as any photo trip. In fact your own backyard offers the best opportunity to learn to develop photographic potential. And, there is no better place to gain valuable experience in finding solutions to photographic problems we all encounter in the field.

Look for a unique perspective.

Create feeding stations for birds and squirrels.

Take the time to let wildlife become used to your presence.

Build a blind if you have shy wildlife species.
