Rough-legged hawks and the advancing spring

Through the winter, Rough-legged Hawks, as with the adult above and the juvenile below, keep watch over the Prairies.  These hawks are equipped for the cold temperatures and many choose to skip the migration and over winter here.  As the weather warms, their cousins, the Red-tailed, Sharp-shinned, Cooper’s and Broad-winged Hawks are starting to return.

One of the great joys of spring for me is the return of these hawks to the fields and grasslands.  However with a few great encounters with the Rough-legged hawks shown here, I’m not in any particular rush.

The robins have been coming home for the last couple of weeks and a flight of about thirty Dark-eyed Juncos swarmed our backyard a couple of days ago.  So, spring seems close at hand.  I’m looking forward to more time with all the different hawks that spend their summers raising chicks here.

Eagles along the Grand Valley Road

Our family went for a drive along the Grand Valley Road northwest of Cochrane a few days ago in search of raptors of any description.  This road is nice drive that is rarely busy and can often yield sightings of owls, hawks or eagles.  In a hilly farmland area we noticed a number of ravens circling around a stand of trees in a field a couple of hundred metres off the road.  When we pulled over to see what the focus of their attention was two coyotes bolted out from under a large cedar and sprinted across the open into the thicker forest on the far side of the field.  Looking back to the spot where they started running we could see a carcass that had been mostly picked clean of what, judging by one of the horns that was sticking up, appeared to be a bison.  As it was on farm land it seems likely there were bison being raised here but there were no other farm animals within sight to confirm that theory.  With coyotes, ravens, magpies and probably a number of other predators drawn to this unfortunate beast, its herd was likely as far away from this spot as the fences would allow.  So, we were watching the ravens which were squawking and pestering the smaller birds picking at the  scraps when Bobbi noticed a Golden eagle (Aquila chrysaetos) approaching from down the valley.

We already had the long lenses out so we were able to photograph the bird as it flew overhead towards the other birds.  Two ravens also saw the eagle inbound and flew up to harass this new attendee.  The three looped around the trees for a minute before the eagle landed in one of the high branches and the black birds returned to ground.

During this chase, the overcast skies took on a more threatening tone and soon a soft snowfall turned into a blizzard.  I thought the Golden eagle would wait out the height of the storm from the perch so I kept looking around to see if the coyotes, or anything else, came back.

Out of the sheets of snow a Bald eagle (Haliaeetus leucocephalus) swooped in and took up a spot on a tree near to the Golden.  This had turned out to be a great encounter and when a couple more Bald eagles flew in and around over the next half an hour, it continued to get better and better.  The snow did finally ease up and there were opportunities for nice flight images.

The lighter skies appeared to spur one of the Bald eagles to say goodbye to a raven it had been sharing a tree with across the field and glide over to the bison skeleton.

This eagle brought a good amount of conviction to its scavenging intent and it chased off all of the passerine that had been crowding on the ground.

When we moved on, this eagle was alone on the ground having successfully landed and taken ownership of what remained.

The Golden eagle had disappeared and two Bald eagles were perched where they could keep an eye on the bones.  The collection of black birds were scattered in singles and small groups around the scene though none strayed close to the eagle holding dominion on the ground.  The last wildlife we saw as we drove away were the coyotes trotting along the hill towards the farm-house keeping their distance while still keeping an eye on the bison.


Rough-legged Hawks – they are everywhere…

… And that is a great thing.  Everywhere may be an exaggeration but if you drive along the range roads west of Calgary or hike along the edges of the fields around the Springbank and Bragg Creek areas, you are very likely to spy one of these beautiful birds perched on a treetop or telephone pole.  If you are lucky, or have the time to wait, you can see them gliding over grassy areas searching for the small creatures that they prefer to dine on.  In my wildlife searches this winter, I have enjoyed seeing many of these hawks.

Below, a couple of hawks working the fields around the Springbank Airport came close enough and stayed around long enough for me to photograph.

Great Gray Owl flights and perches in Bragg Creek

I had a great morning earlier this week watching this female Great Gray Owl.  She flew to several perches as she moved from the forest into the open meadows nearby.

She was watching for quite a while at each stop.   She seemed pretty relaxed, without any great urgency to hunt.

Down the field, the sun was reaching into the trees.  The light that got through was really beautiful.

I’m hoping to hang out again over the weekend.  We’ll see if she is thinking the same thing.
