HUNTING IN WINTER
From 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.
The 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.

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

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.
Slamming 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.
Three 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.
