THE FALCONER

2 Replies

 

 

falconry-23I couldn’t help but notice two hooded falcons perched on the back seat of a VW bug in the grocery store parking lot where I worked. ( forty-five years ago!)  A guy with a ponytail drove it.  When I said something about the prairie falcons, he looked a bit surprised.  I guess nobody had ever correctly identified his falcons before.  That’s how I first met Terry Heath.  And with that introduction, we shared a short conservation that ended with Terry inviting me to photograph his hunting falcons. As I tagged along on hunting trips It became clear that for Terry, falconry was no hobby, nor was it just a sport hunting venture.  No, Terry was in the grip of a full-blown obsession with falcons.

THE PRAIRIE FALCON

falconry-24Week-old prairie falcons huddle together on a simple scrape at their cliff eyrie. The aggressive divebombing adults give Terry a glimpse into the potential flight characteristics of the young falcons.

A PEREGRINE NAMED ANGEL
falconry-2Another mallard for the bag.  Every flight of Angel, the peregrine, was stunning,

falconry-26Angel suddenly reappears out of nowhere to stoop on the lure. (above)    For a few worrying minutes, Angel was nowhere to be seen.  Had she made a kill out of sight?  A big worry. falconry-25  A falcon with a full crop is difficult to coax to the glove.  Candy (right) was a fixture on the hunting trips.   But once, after hawking for pheasants, Candy went missing and didn’t return to the car.   Before leaving Terry threw out his coat.  The next morning there she lay, waiting.

falconry-35Searching for suitable quarry for the falcons led us out to the edge of the lava flows of eastern Idaho. Passing a pair of ravens hanging out along the road, Terry slows and pulls over a couple of hundred yards down the road.  Stepping out of the van Terry removes the peregrines hood and lifts the falcon above his head.   In an instant, the peregrine is off the glove and power-pumping those long, slender wings into the wind towards the dumb-struck ravens.  From a jump start, the ravens took flight and started to climb. Now, these ravens share the sky with all kinds of raptors from goshawks to golden eagles so the sudden appearance of a peregrine is no big deal.   But this one had them in the crosshairs!   Though the peregrine’s power of flight is legendary, she could not outclimb the ravens.  A peregrines advantage is on the way back down and the ravens knew it.  The flight was quickly a quarter mile above the sage highlands and climbing.  But the persistent peregrine wouldn’t give up.  As the flight threatened to disappear, out came the lure.

falconry-14Desperate to get back to open water, the mallard deploys futile last-second maneuvers. The peregrines focus is clear.  Mine, not so much.

 

GRAY JAY

4A pair of gray jays have finished their nest by early April.

I first saw the gray jays as they flew across the road in front of me.  They both carried loads of building materials in their bills.  The next day I went searching for their nest.  It was rather easy to find as they were both busy with construction.  The nest was about twenty feet high in a medium-sized black spruce.  They had completed a loose bowl of dry spruce twigs and were currently engaged with stuffing this framework with insulation.  The pair gathered black, grizzly hair lichens as well as spruce grouse feathers.  But their most prized finds were the long soft plumes of the northern hawk owl.  After delivering a load of insulation, the birds would hop into the nest and push with bills and feet as they rotated around in the nest, fitting and forming it to just the right shape.9The female begins sitting on the nest and a week later her clutch of spotted eggs is complete.  The pair is quiet at the nest site and does not attract attention of those nest raiders, magpies and ravens.  When a red squirrel was spotted nearby it was dive-bombed by the male gray jay and driven away.

8For nearly three weeks the female incubated her four eggs.  A few times a day she will leave the nest but only for a few minutes, perhaps to drink.

11The male gray jay shows up at the nest about once an hour or so to feed his mate.

5Laying eggs is an energy drain and the female spends hours sleeping.

10 Early nesting grays jays  must be able to handle cold, wet conditions in their Alaskan habitat.

12Both adults help feed the quickly growing gray jay chicks.  Gray jays store amazing amounts of food including carrion and I wondered if they would feed their cached supplies to their chicks.  But Instead they foraged the ground for insects and larva, much better food for the new chicks.

3851As the chicks grew the gray jays cached stores of carrion became more important.  And it quickly became apparent that the nest would never hold four growing chicks for long. By the time the chicks were about two weeks old, they jostle for the best position at the nest. I witnessed deliberate attempts by the larger chicks to force their smaller siblings out.  One morning there were just two chicks left in the nest.  Below the nest on the ground were the missing chicks, both dead.  From human eyes, a tragic event.  But for nature, another one of those mysteries of survival.

Come July of this year the name of the gray jay will change once again.  They will  officially be known as the Canada jay.  And like camp robber and whiskey jack, gray jay will be just another nickname used to describe this gray-colored jay of the northern forests.

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.

533-19-1An adult northern goshawk feeds on a snowshoe hare.

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.

533-48-1High in the canopy a female tends to her day old chicks.

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.

NationalGeographic_492285

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.

 

 

 

HAWK OWLS, HOME HUNTING

A pair of northern hawk owls check out the view from atop a prospective nesting cavity. Hawk owls, like other owls, do not build a nest but use natural cavities and bowled out snags.  The male establishes a territory that includes potential nests sites, but it seems to be the female who makes the final choice of snags.

After settling on another snag, the female incubates her eggs.  Hawk owls nest early, usually in late April and will endure winter conditions.

DSC4708At nearly four weeks a fledged great gray owlet has jumped from its nest to the forest floor.  Free from the confines of the nest, (I too am finally freed from the solitary confinement of my photo blind)  the owlet walks and leaps to a place to perch.

Fledged owlets move about fifty to a hundred feet every day,  picking out a slanting tree to climb.   The ground is a dangerous place for the young, flightless owls. The mobile owl family becomes more difficult to locate by the day.

Female great gray owl holds another red-backed vole just delivered by her mate.  The well fed owlets are not hungry at the moment so the vole will be placed in the nest for later.  For nearly four weeks I had a rare and intimate view of the owls family life at the nest.

DSC7601As the female raises up from her brooding, she gives me my first look at the tiny owlets.

DSC9643The owlets hatching over a period of about a week account for their age and size difference.  Competition among the owls for food favors the older owlets.  The smallest owlet, here just a couple of days old, could not hold its own and one morning it was gone.

Watch video of male delivering a red-backed vole. (above)

DSC3218

After a couple of weeks there is no longer a need for constant brooding and the female finally gets a little time to herself.  But even then she stays close and alert for danger.  One day a pair of ravens hung around the nest in an attempt to harass her from the nest long enough to steal a chick.  She held tight and her mate arrived to chase the ravens about.  Eventually the ravens left.

DSC6522A female great gray owl spreads her wings as she gently lands on the edge of her nest to resume incubating her four eggs.   For two months this nest is the nucleus of activity for a pair of great gray owls.  Owls do not build their own nests. Instead they use a variety of ready-made and vacant nests, like this one built many years before by northern goshawks.  The great grays I had photographed three decades ago in Idaho prefered the bowled out tops of large broken pine trees for their nests.

DSC7359Eggs laid in the third week of April must be protected from the weather, as incubation begins with the first egg. The female does all the incubating and will sit on her eggs for thirty days.

DSC7473To gain access to the nesting great grays, more than fifty feet above the forest floor, I scabbed two long extensions ladders together and added an additional extension using two by fours.  I had located the nest thirteen years ago.  The three-foot wide nest was built by northern goshawks in a towering quaking aspen. Every spring I’d hike to the remote nest site to check its status. Goshawks had used the nest only once during the last thirteen years.

From my self-imposed confinement in the lofty, swaying photo blind, I witnessed much more than just the daily activities of the great gray owls.  The female owl and I watched red squirrels, that rarely seen red squirrel predator, the marten, groups of migrating caribou, and a variety of bird life.  Early one morning, not long after arriving, a huffing grizzly bear sow and yearling cub who had caught my scent quickly moved off beneath the blind.  Once a curious cow moose who could hear my camera clicking finally looked up.

DSC5985

DSC2049A couple of times a day the female flies off the nest to drink, cast her pellet and perhaps stretch before returning to her precious clutch of eggs.

DSC6427The male hunts for his mate and has just arrived with prey, a baby red squirrel.  The male, who hunts during the day using sight and sound, is an opportunist and preys on a variety of small birds and mammals.  Red-backed voles are by far the most important prey but shrews, small birds, and young snowshoe hares are also prey.  Adult red squirrels are usually too alert and quick to be given much attention by the hunting male.  But young squirrels, probably raided from their grass and sphagnum nests, are regularly on the menu.

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.

Click on the left side of the audio bar to hear the song of the boreal owl.
