PHOTOGRAPHING AURORA BOREALIS

Leave a reply

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.

RED SQUIRRELS, HOARDING BEHAVIOR

32-15-185Red squirrel carries mushroom which will be added to its growing winter larder.

32-15-131Each fall in preparation for a long, cold winter red squirrels here in Alaska begin a frenzied gathering of food.  Their hoarding behavior has very important survival benefits.  Gathering food in the fall, before snows arrive will save time and energy.  During the short days of winter red squirrels need to conserve their energy.  When snows cover the forest floor red squirrels are more exposed to predation and the less time they must spend searching for food the better.

MUSHROOMS AND RED SQUIRRELS

Red squirrels work overtime in late summer/early fall gathering mushrooms.  I spent several days this week photographing them.  Though red squirrels can be a nuisance around our wilderness home I try to tolerate them. Our current red squirrel seems to be satisfied living a life in the wild so as long as he minds his own business he is on the payroll.  I discourage bad squirrel behavior such as chewing on the house and if they persist, they get that one way ride up to my mean old neighbor ladies place.  And she handles red squirrels just like most of my neighbors do.

LAST DANCE OF THE SOCKEYE

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 →

HUNTING LIKE A HAWK

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.
