Travel Tuesday: Southern Alberta’s Snowy Owl Irruption of 2013-2014

Posted by Dan Arndt

There have been many articles published this year about the incredible, record-setting irruption of Snowy Owls in Eastern Canada and the Eastern United States. For example, over the span of one weekend in late 2013, over 300 individual birds were counted in Newfoundland. In a similar fashion to a story from last winter of a Snowy Owl being seen in Hawai’i (where it was unfortunately shot by USDA’s Wildlife Division), this year one was seen as far south as Bermuda!

You can tell just from eBird that there are Snowy Owls all across Canada and the northern U.S., but relatively few make it further west into British Columbia.

Here in the Calgary area, we’ve been rather lucky as well, as this is the third winter in a row where we’ve been on the receiving end of a fairly large irruption. While I haven’t been out as much this year to search for them as I was last, I’ve still had some fairly good luck, netting four owls in a single day in November in the Beiseker area in mid-December, two owls at once in a single day around Frank Lake in late January, and six owls in a single day in the Blackie area in early February. Some local die-hards have even reported finding as many as fifteen (yes, 15) in a single, all-day trip southeast of Calgary.

This map from eBird shows pretty much what one would expect given those numbers, and I wouldn’t hesitate to consider this the furthest westerly extent of the same population of Snowy Owls responsible for the massive numbers out east.

One interesting thing discovered by Project SNOWstorm is that many of these Snowy Owls are in very good health, which goes against the common belief that these irruptions are the fallout from a crash in the lemming population on the tundra, leading starving owls to search further afield for suitable food to survive the winter. There are some others that suggest that this common belief may be completely erroneous, based on the research of Norman Smith, Tom McDonald, and other researchers in the U.S. and Canada.

Of course, not all the Snowy Owls that make their way down here in the early winter will return north. Even those in great health that simply are unable to adapt to the food supply further south, those that have close encounters with power lines, vehicles, or other man-made hazards will simply be unable to return north due to injury or death.

You might have noticed as well that I tend not to label my Snowy Owl photos as male or female. Based on data collected from Scott Weidensaul and Norman Smith indicate that the usual conclusions of all-white individuals being older males, and heavily barred/marked individuals being young females may be much more complex than previously thought.

One thing that is indisputable by any birder, photographer, or even someone who simply enjoys nature and all of its beauty, is that Snowy Owls are absolutely marvelous creatures, and always a treat to find, whether it’s the first one you’ve ever seen in your entire life, or the twentieth one you’ve seen that day. I’ll never get tired of photographing them, especially when they pose in front of such a nice backdrop!

Expecting the unexpected in the Weaselhead

Feb3

Posted by Dan Arndt

My first visit back to the Weaselhead Nature Area since the Christmas Bird Count in mid-December turned up a much different array of birds. I always seem to find that birding in the Weaselhead, no matter the time of year, comes in fits and starts. In the winter, this is even more pronounced, as there were times where we’d walked for twenty minutes between running into any birds whatsoever, let alone anything less common than a Black-capped Chickadee.

Maybe it’s the abundance of birds at the start and at the end of this walk that sets the tone for the outings here. The first set of feeders were being visited by the usual Black-capped Chickadees, but with them were a trio of Downy Woodpeckers, a male and female Hairy Woodpecker, and half a dozen amorous House Finches, feeding and singing up a storm.

It was quite a sight to watch the female Hairy Woodpecker pick out a seed from the feeder…

… and then climb up the tree a short way, place the sunflower seed into the hole, and crack it open with a few rapid taps.

On our first pass of the feeders at the bottom of the hill, our only real bird of note was this White-breasted Nuthatch, “hank, hank, hank”ing away for no apparent reason, until a second male came into view before the two of them flew off in a scuffle.

While we headed from there to our usual Boreal Chickadee grove, flock after flock of Bohemian Waxwings flew overhead, and we even had a pair of chance sightings of a Bald Eagle, and then a few minutes later, a Rough-legged Hawk, which bulked up our species count just a bit more for the day.

Upon arriving at the grove, Bob stopped the group abruptly to point out a single Brown Creeper feeding at the base of one of the larger spruce trees and I snapped off a couple of photos of this elusive species. I suppose like most of the other birds we found today, these birds simply don’t care what a groundhog says about the season, they know that it’s time to breed soon, and they need to collect their energy before things get into full swing!

We did also find a lone Boreal Chickadee after a few minutes of patience, but unfortunately it didn’t stick around long enough to pose for a photo. Shame!

And so began a long, quiet stretch of our walk. While we did have a few flocks of Black-capped Chickadees with the odd White- or Red-breasted Nuthatch thrown in, we observed no Northern Goshawks, no Merlins, no Cooper’s or Sharp-shinned Hawks, and the largest Bohemian Waxwing flock we found deeper into the Weaselhead was a whopping four (yes, 4) birds.

It all paid off though once we began our trip back. While I was bringing up the rear of the group, the lead observers spotted a female Pileated Woodpecker, which we had seen earlier on in the walk, but this time she was much closer. She flew back into some deadfall, out of sight, and while the rest of the group trudged on, I thought I’d try my luck photographing her.

What do you think?

And closer still.

By the time I reached the feeders again, the group was well ahead of me, and I wouldn’t catch up to them until we reached the end of our walk, but in the time since they had passed the lowermost feeders, a few surprises had moved in, in the form of a pair of Dark-eyed Juncos, a lone American Tree Sparrow, and a surprising first-winter White-throated Sparrow, picking through the seeds on the ground.

I didn’t tarry too long, but thought I’d pause for a moment at another of the lower feeders, as this male Downy Woodpecker obliged me with a few shots while he finished his brunch.

All in all, another very successful day, and while the light was flat and gray, the birds were accommodating, vocal, and up to no end of entertaining antics! Next week, we head into Bebo Grove in search of the American Three-toed Woodpecker!

Have a great day, and good birding!

Sunday Showcase: Goshawk Feeding

Jan5

Karen and Roger Bolton had the unusual experience of seeing a Northern Goshawk eat a Blue Jay in their yard in Glamorgan, SW Calgary, on December 7, 2013. These powerful raptors are scarce in winter in the Calgary area. They feed on game birds like pheasants and partridge; rabbits, and rodents, as well as songbirds. (Click on the photos to enlarge them.)

Sunday Showcase: Winter Waxwings, Kinglet, and Chickadee

Tony LePrieur photographed these birds in Fish Creek Park on December 15, 2013.

Harris Toth had this little Northern Saw-whet Owl visit his yard in the Parkland neighbourhood of SE Calgary on December 15. The same night, another (or the same one) was seen in Queensland, only about 2 km away. These owls are quite common in the summer and there are always some around here in the winter, but they are strictly nocturnal so they aren’t often seen.

Tony LePrieur found this male American Three-toed Woodpecker, and other birds, in Fish Creek Park on December 8.

Refinery Park and Lower Beaverdam Flats – An Eagle’s Paradise

Dec9

Posted by Dan Arndt

Well… maybe paradise is overselling it a bit, but we did a good show from a few Bald Eagles on our outing this past Sunday! Three days this week the outings had been cancelled due to extreme weather and extreme cold. Unheard of for the hardiest of our leaders, but everyone has their limits! Unfortunately, the weather early this morning kept most of our participants away, so we headed off with three leaders and one hardy participant into the cold and the wind.

Refinery Park and Lower Beaverdam Flats

What started off as a cold, blustery and grey day turned into some amazing blue skies, much warmer weather than we’ve seen all week, and some great opportunities to get some action shots. Needless to say though, it took a little bit for everyone to get going, including some of the first groups of birds we saw. This backwater along the Bow River was completely full of mostly Canada Geese and a few Mallards for good measure.

Even the Bald Eagles looked completely unimpressed in the cold and the wind. The expressions of utter contempt for both us, and the hundred or so waterfowl just below them in the water, have led me to nickname these two as Hekyll and Jekyll.

As we turned back to follow the river bank southward, things started to pick up. The sun was making a serious attempt to break through the meager cloud cover to the south and east, and some of the birds began to show a few more signs of life. A third immature Bald Eagle was being chased (but not quite harassed) by the Common Raven keeping a keen eye on it from below.

As the wind picked up a little, it caused the birds to begin to fly up-river, allowing some half-decent flight shots. Along with the wind picking up, the sun finally began to break through, and provided some great light for the remainder of our walk. First up, a male and female Common Goldeneye, flying by within a few minutes of each other.

A moment later, a female Barrow’s Goldeneye flew by, and a male of the same species broke away from the Canada Geese at the far shore and made his way into the middle of the river shortly after.

This group of Buffleheads touched down in the water about halfway into the river, showing off their bubble-gum pink legs. That’s one lucky male Bufflehead getting the pick of mates this winter!

And last but not least, this male Common Merganser flew by quite close, showing off his bright red bill and a hint of green in the head as the sun began to shine.

We continued south along the river without seeing too much else of note, but shortly after we turned back on one of the inner pathways, this subadult Bald Eagle flew by behind us and alighted in a tree, closely tailed by a flock of scavenging Common Ravens, looking for whatever scraps they could manage to steal from the wary bird of prey.

A couple of Black-billed Magpies even came in for a piece of the action. Or maybe just a piece of the Mallard.

If there’s one thing I love most about winter birding in Calgary, I’d have to say that above the Snowy Owls, above the winter finches, and even above the odd vagrants we’re gifted with every couple of years, I certainly love seeing the influx of Bald Eagles the most. One of the groups this week in Beaverdam Flats recorded no less than ten (yes, 10) Bald Eagles in a single outing. While it’s not quite the same as the incredible numbers seen on both east and west coasts in the height of the season, it’s still an incredible treat to us landlocked city-slickers to have such unrestricted access to these regal and immensely powerful raptors.

That brings us to the end of our Autumn Birding Course for 2013. We’ll be picking back up in January again, but between now and then I’ll be sure to keep you all updated on the Christmas Bird Counts I’m taking part in, as well as the various travels that I happen to find myself on this holiday season!

Thanks again for reading, and good birding!

Sunday Showcase: Pileated Woodpecker

Dec1

Bernard Tremblay got these amazing close-up photos of a male Pileated Woodpecker feeding on a fallen log yesterday, November 30, 2013, in the Weaselhead Nature Area in SW Calgary. After a few minutes the woodpecker was scared off by a Merlin.

The camera used was a Nikon 7000 + AF-S Nikkor 300 mm lens + Nikon AF-S teleconverter TC -14E 1.4 x. The camera settings were: 420 mm 1/1600 sec f5.6 ISO 2000.

Male Pileated Woodpecker. The red crest extends all the way to the base of the bill; on the female the red doesn’t reach the bill. There is also a red mark from the bill to the throat, which is black on female birds.
