Sunday Showcase: Long-eared Owls

Posted by Bob Lefebvre

Long-eared Owls are fairly common in the Calgary area and breed in and around the city, but they are nocturnal and so secretive that many birders go years between sightings. In early summer I was told of a Long-eared Owl nest in the city with young in the nest. Here are some photos of this family taken by several local birders.

(Note: The birds are secretive since they are vulnerable to predation from Great Horned Owls, magpies, ravens, crows, porcupines, and hawks. It is very important when observing them to not give away the location of the nest. This nest was very close to a public pathway. Although the young have fledged long ago now, the owls may nest in the same area again next year, so I won’t reveal the location. I did share it with Dan Arndt, Andrew Hart, and a couple of young birders who had never seen this species before, but we didn’t want to put undue stress on the birds or draw attention to the location by having too many people go to see them.)

June 11, 2016. Only one young remained in the nest. We were concerned that they had been predated, so stopped visiting for a while. But later on we saw two fledged young together near the nest, so they may just have fledged at slightly different times. Photo by Dan Arndt.

On June 26 Andrew Hart and I went to see if the last of the owls had fledged. The nest was empty, but we found two very vocal and active young owls nearby.

Book Review: North American Owls by Dr. James R. Duncan

Jul26

Re-posted with permission from the Bird Boy blog. Originally posted July 19, 2015. See the Bird Boy blog at this link. It is based in Canmore, so Calgary-area birders may want to subscribe to it.

North American Owls – A good book?

“Owls are fascinating to us because they are simultaneously foreign and familiar.” So states Dr. James R. Duncan on page 6 of his book The Complete Book of North American Owls. He goes on to explain the biology and unusual features of North American Owls. Further into the book, he has a complete profile of every known species of Owl in North America. The result is an all round excellent guide which is essential to any Owling expedition, whether diurnal or nocturnal.

The introduction is informative, but manages to convey its large amount of information in an interesting way. Mainly on the biology and ‘special adaptations’ of owls, this document starts off with captivating sentences that show the relationships between owls and humans. On page 6, he states it well and plainly. “When owls and humans meet, it is sometimes hard to know which is more fascinated, startled, and sometimes even frightened.” Once he has the reader in his grasp, he progresses to the more scientific parts. He explains the intricate mysteries of owls and their amazing arsenal of survival skills. This entirety is built upon the excellent images that are not simply pictures of owls, but relevant and comprehension-aiding parts of the book.

This brings me to my next point: photography.
The photos are all clear, and have the proper photo credits. The more common species have multiple photos, at least one of both adult and immature, while the lesser known species may have only one or two. The photo choices and placement fits and does not get in the way, but helps with understanding the species. I did, however, notice one slight error: the front page photos from the Northern Pygmy Owl and the Mountain Pygmy Owl had been swapped! Apart from this, everything was exceptional for all the pictures.

Most owl species in the book have 1 to 4 pages of detailed descriptions and photos. On each owl’s front page, the Owl’s common and Latin names are top of the sheet, precise range maps and a general physical summarization lie beside the text. In the writing itself, the primary information is the song, range, food, and nesting. Behaviour and nesting habits are also mentioned. I found that the author tried to insert some interesting little pieces of info that may not help with identification, but are interesting nonetheless, including quotes such as this: “It [the Northern Hawk Owl] roosts within forested stands at night, and has been seen flying for such cover from open areas when Great-horned Owls emerge at dusk to start hunting.” (page 128).

The book is well organised, a 25cm tall, 19cm wide, 2cm thick volume, the font is easy to read and a reasonable size. It is not so much a field guide as a home guide, in my opinion, meaning that I would keep it at home and read it there rather than take it into the field (although if you’re going owling, take it when you can, it would be very useful).

To conclude, the pictures are good, the writing is very informative, and you can tell that the author has made an effort to keep it interesting. All in all, Dr. James R. Duncan has succeeded in making one of the best and most influential owl guides that I have ever read.

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

Feb11

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.

Sightings range from October 1, 2013 to February 10, 2014

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!

Have a wonderful week, and good birding!

The Long Walk in Lafarge Meadows

May22

Posted by Dan Arndt

One of the longest walks with the Friends of Fish Creek birding courses is the Sikome Lake to Lafarge Meadows trip. With a variety of ponds, wooded areas, river access, and open fields, the number of different biological niches that are filled along the route make it hard for me to skip or overlook any one area over another. This is one of the reasons that when I found out it was available for the May Species Count weekend last year, I jumped at the opportunity. Sure it’s a whole lot of walking, and there are some other areas that can be covered by driving, or still others that are smaller and can be completed in a couple of hours, but this week’s walk with the Friends of Fish Creek on Sunday was a great scouting trip, and was absolutely worthwhile.

Sikome Lake and Lafarge Meadows, the longest walk.

Right off the bat there was activity. While we waited for the main gate to be opened for us, we heard our first House Wren and Clay-colored Sparrows for the year, along with at least three Ring-necked Pheasants and many, many Savannah Sparrows. Once we got to the south parking lot though, we the number of new species jumped again. First, a Cooper’s Hawk was waiting for us in the parking lot, a few Black Terns flew overhead, and hundreds of Cliff Swallows swirled about high up in the morning sky.

I had heard that the owlets at Sikome Lake had fledged last week, and when we came upon the two young, we could not have asked for a better scene. We were treated as well to our first good views of a Violet-Green Swallow, standing out distinctly from the many Tree Swallows who had taken up nests in the wooded grove.

Great Horned Owlets

When we finally tore ourselves away from the amazingly adorable owlets, we headed to the first set of ponds and were treated to even more new sights. First, an adult Killdeer performing its broken-wing display, leading us away from a very well hidden nest that no amount of searching would have found. Over the pond, a trio of Forster’s Terns called back and forth, one pair even displaying and finally mating. A female Belted Kingfisher looked on with disdain, hoping they wouldn’t scare off all the fish. As we headed back south, a few Spotted Sandpipers were courting as well, and while this pair wasn’t quite as much interested in exhibitionism, a few we found later on in the day didn’t seem to mind our intrusion one bit.

On the south side of the bridge were more delights. Our first Yellow Warblers were calling from the woods repeatedly, until their calls became the dominant noises surrounding us, but the distinct call of a low flying Swainson’s Hawk was definitely impossible to miss!

Our trip to the far south end didn’t turn up any new species, but did turn up better looks at some old ones, including Yellow-headed Blackbirds, Cinnamon Teal, and Red-necked Grebes, with no less than six pairs nesting on the pond this year. We headed back, deciding to call it a day after four hours of walking and birding, but even still we added two more clear sightings. First, this Clay-colored Sparrow singing on the fence on the south side of the bridge, and the clarion call of a Baltimore Oriole on the north side, just as we called it quits.

It was a great day to be birdwatching, despite the gray skies!

Next week we’re off to the Weaselhead for the May Species Count. This promises to be an amazing morning. See you then!

Spring Migrants and a warm welcome at Carburn Park

Apr29

Posted by Dan Arndt

Finally we had a warmer day, and while there was a little wind and the light wasn’t perfect, there were certainly a few moments where everything made it all worth while, even the last few weeks of dreary, snowy misery.

Carburn Park

We started, and finished, with the show-stealers of the day, and it made it difficult to really have anything match the incredible sight.

While Dad was protecting the young, the mother and babies were well guarded and seemed to be completely unfazed by the presence of 14 people checking out the area.

In the first pond at Carburn Park, we saw quite a bit of evidence of beaver activity, and we did manage to spot a pair of them swimming about, with this one getting close enough for me to photograph.

Beaver

While we headed south in the earliest start of the season so far, we got lucky with a few birds we hadn’t seen before, like the Song Sparrow and Savannah Sparrow, but neither were in any position for me to get photos. Swarmed by low flybys of literally hundreds of Tree Swallows at a time, our eyes were on the sky much of the time, allowing me to spot this distant Rough-legged Hawk circling above the parking lot, most likely rising on thermals to continue his northward migration.

Rough-legged Hawk

As we neared the parking lot again, and scanned along the river to see what we could see, we were gifted with this beautiful flyby of a male American White Pelican. Awesome.

We headed up along the bank of the river, and while we saw a good number of Franklin’s, Ring-billed, and California Gulls, and even bigger numbers of Tree Swallows, but due to the number of boats on the river, the photo opportunities were slim. That all changed once we turned back onto main pathway and reached the second pond. We got really good looks at Red-necked Grebes and a single Common Loon, and I knew that if they stuck around, I’d be back later on with the Swarovski ATX 85 to take some much closer shots.

Common Loon

Our next good views were on the river, one of which was, I think, one of the most surprising of the day. A lone Yellow-headed Blackbird was flocking with a group of European Starlings. For a bird that is almost always seen in cat-tail wetlands, seeing it foraging on the bank of the river was really odd!

Yellow-headed Blackbird and European Starlings

Another of the awe-inspiring sights was the Tree Swallows banking, diving, and feeding over the Bow River, and I think we had just as much fun watching them.

We headed back, prepared to call it a day, and had our best views of a pair of Osprey in the distance.

After the rest of the group left, I returned to the bank of the second pond to see what I could see through the scope, and get some better photos of the Red-necked Grebes, Common Loon, and I ended up getting some nice ones of the Great Horned Owls as well!

Aren’t they just adorable?

Thanks for reading!

Next week, we’re off to South Glenmore Park, to see what we can see on the Glenmore Reservoir, and maybe luck out with some early arriving warblers and a few more sparrows.

Good birding!

Sunday Showcase: Great Grey Owls of Grand Valley Road

Apr14

Posted by Dan Arndt

In late March of this year, Paul Turbitt and I headed out to Grand Valley Road in search of Great Grey Owls, and I had both my best day in terms of numbers of owls, but also in terms of photos. This individual owl seemed incredibly tolerant of people, and patient enough to make three hunting attempts in the hour that we sat and watched. More than a few times, the owl flew in our direction, seemingly unthreatened by our presence.

Enjoy the photos.

This Great Grey Owl was little wary when we first showed up…

But after a little patience and some sun to distract, we were all but forgotten about.

This owl must have felt a little exposed though, as it kept a keen eye on the skies.

Oh! What’s that?

Looks like lunch!

Hmm… nope, missed it.

I blame you, you know.

Ready for takeoff…

Maybe the hunting’s better down here…

Nailed the landing!

And one more wing-spread shot. Can’t get enough of these gorgeous owls!

Bye for now!

Friends of Fish Creek Autumn Birding – Week 13 – Bow Valley Ranch and Sikome Lake

Dec3

Posted by Dan Arndt

I will always remember my first visit to the Fish Creek Provincial Park Headquarters building in search of birds. It was a cold winter morning, quite similar to yesterday, and we were in search of some Great Horned Owls. We found them, of course, as the owls here are almost as reliable as the sunrise and sunset, before heading off and exploring the area around the Headquarters, and then down to Sikome Lake to look for some more owls and check out what was on the river.

This week was very similar, with maybe a few more surprise species popping up, a couple of near misses on the owls, but all in all, it was another wonderfully successful walk.

Since this walk covers two main areas, I’ve added two maps instead of your usual one for the same low cost as you pay for your current blog subscription! I know with the holiday season in full swing, money is tight, so I’m passing the savings on to you!

We started up at the Headquarters building area known as Bow Valley Ranch, and had quite a bit of success up there after some moderate search efforts. In the end, everyone left satisfied and content with what we had seen so far, with hopes for many more birds to come.

Bow Valley Ranch

The pair of Great Horned Owls that have been consistently found here all week, and to my understanding, for well over ten years, were our primary goal here at the east side of the Fish Creek Provincial Park Headquarters building. In our searches, we were mobbed by a fair-sized swarm of Black-capped Chickadees, but as is typical for these mixed flocks in winter, we got a little added bonus of a lone Brown Creeper.

Brown Creeper

Nearby, there was a terribly dedicated Downy Woodpecker drumming at a small stand of low bushes in search of some tasty insect larvae or some other arthropods hidden in the bark.

We spent a good ten to fifteen minutes looking for the Great Horned Owls, walking to the far east end of the pathway, and on our way back we were greeted by the high-pitched flight calls of some White-winged Crossbills picking at the cones at the peak of the spruce rows.

White-winged Crossbills

We were about ready to call our search off when one of our keen-eyed birders noticed a small clump of something dark and grey huddled up against the trunk of one of the spruce trees.

There is an owl in this picture, I swear.

A bit of hand waving and flagging down some of our group to come get better looks wound up with a fairly decent angle in the dull, overcast light, and it was clear that this was one Great Horned Owl that did not want to be disturbed this morning.

Great Horned Owl

Once we had discovered our quarry and had our fill of its excellent camouflage skills, we headed west towards The Ranche, and out in the fields south of the compound was this White-tail Deer buck, casually browsing in the low bushes and making his way eastward along one of the many deer trails in the park.

White-tail Deer buck

Our last new bird at Bow Valley Ranch was this lone Red Crossbill, calling and preening and generally looking a bit out-of-place in a flock of White-winged Crossbills.

We headed back to the vehicles shortly thereafter and headed south to Sikome Lake. There were plenty of waterfowl in the fairly swift waters of the Bow River that morning, and quite a few of them were quite close to shore, allowing good looks, and excellent photo opportunities.

Sikome Lake and Boat Launch

Once again, it took a bit of searching for the Great Horned Owls before we found one lone lookout.

Great Horned Owl

This area is also one of the must-visit places within Fish Creek Provincial Park, mostly because of how familiar the birds here are with humans. While there may be some compunctions against feeding wild birds, the Downy Woodpeckers, Red- and White-breasted Nuthatches, and of course the ever-present Black-capped Chickadees are comfortable enough to eat right out of one’s hand.

White-breasted Nuthatch

Once we had our fill of hand-feeding the birds, we headed down to the edge of the Bow River to see what waterfowl we might find. The river was full of Canada Geese, Buffleheads, Common Goldeneye, and even a few Barrow’s Goldeneye. We also did manage to pick out a subadult male Common Goldeneye just coming into his adult plumage, which was quite interesting to see!

As we headed north along the river bank, we had a fairly low flyover of an adult Bald Eagle which is always a welcome sight… unless you’re a duck.

Dropping down into the poplar stands on the inside bank of the Bow River, we stopped for a moment to glance over what appeared to be skunk tracks, and continued north back up the slope in the quiet woods to find this female Hairy Woodpecker doing what they do best.

Skunk Tracks

Topping off our day was this patient juvenile Bald Eagle watching over a flock of Canada Geese as the snow began to come down in heavier flakes and much faster than before.

As we headed back to the parking lot to head home, we did have a close encounter with a Coyote which dropped down into a creek bed and out of sight before popping up right along the trail we had been following not half an hour before, flushing up some of the Canada Geese we had been so close to earlier in the day.

Coyote

It has been quite the productive, beautiful, and diverse course so far, and it’s a bit sad to see it end in just one more week, but on the good side, it also means that we’ll be well on the way towards spring migration with the start of the 2013 Winter Birding course starting up on January 7th!

See you here next week!

Travel Tuesday – Birthday Birding with Bob

Jul24

Posted by Dan Arndt

As I have done for a few years now, I decided this year that I would take a day off around my birthday and get a few new life-birds and a few other target species off my list. As the week came closer, the weather looked more and more like it simply was not going to cooperate, and when my birthday arrived, it rained straight through the day. Two days later, the clouds cleared long enough for Bob Lefebvre and I to get out and find some birds. While the wind was more active than I would have liked, the day turned out quite nicely, topping out at 27 degrees C, (or about 81F for our readers south of the border).

We planned our route a few days before to tie in with Bob’s scheduled trip on the Loon survey. We would hit the entrance to Big Hill Springs Provincial Park, then go over to Horse Creek Road, up Grand Valley Road, then down through Bragg Creek to the Brown-Lowery Provincial Park, then back up to Leisure Lake to do the loon survey. Finally, we would make a trip down to Frank Lake, to get Bob’s shorebird count up, and finally we would head home from there.

Birthday Birding Locations

With our route planned, we headed out at 5 AM, and got to our first site just as the sun was clearing the horizon.

Bob had heard of a number of Rock Wrens on territory just north of the main entrance to Big Hill Springs Provincial Park, and when we stopped the car and listened for a few moments, it was immediately apparent that they were still present. With a little help from some call playback, we were able to get some extremely good views of one of the males loudly defending his territory.

This bird is appropriately named.

Rock Wren closeup

We headed up Grand Valley Road shortly after, in search of one of the many Great Gray Owls that have been seen there many times this spring and summer, but also historically seems to be the best spot around to find them. We drove for quite some time before Bob’s eagle eyes spotted one flying behind a gravel pile, so we stopped and waited, and moments later, it flew out and onto a nearby fencepost. This reclusive individual only stayed around long enough for us to get a handful of photos, but we did manage a few that turned out.

Watching us very closely.

Great Gray Glare of Death

As we headed down to Horse Creek Road, the wind had picked up quite a bit, and when we stopped to listen for the rails distinctive clicking calls, we could barely hear anything over the wind. No rails were heard or seen on this trip, but we did get some very nice close ups of these Wilson’s Phalaropes.

Wilson’s Phalarope

After that brief stop, we headed straight down to Brown-Lowery Provincial Park, and got incredibly close views of another life-bird for me, the Cape May Warbler. It seemed that there were quite a number of them in the park, most on nests, along with Wilson’s Warblers, which never quite came out to give us decent views.

Bob’s annual Loon Survey up at Leisure Lake was part of our trip, and we did manage to circle the lake, find the nest and eggs, and saw both the male and female Common Loon out on the water.

We finished up our day out at Frank Lake, and planned to head down to Basin 2, where we saw a huge number of species, and I was able to add Northern Harrier to my year list finally as well, but as far away as it was, paired with the heat, the photos simply would not suffice. So instead, here’s a Marbled Godwit to distract you.
