The end of Winter at Pine Creek Waste Water Treatment Plant

Posted by Dan Arndt

I know, I know. With the title of the last two Monday morning blog posts having to do with the beginning of spring, or the end of winter, you’d think it would actually be over by now, wouldn’t you? Unfortunately, one last winter storm made our last outing with the Winter session with the Friends of Fish Creek live up to its name. Blowing snow, -12 degrees C temperatures, and a whole lot of ice on the river made it feel like an outing more in line with early January than the last day of March! The quantity of species seen though, did begin to look a bit more like spring. The number of waterfowl species that were laying over on the south end of the Bow River in Calgary certainly showed us that spring, indeed, was finally just around the corner. In fact, there was so much activity on the south end of our trek that I’ve had to blow up the usual map to give proper detail on where each species was seen!

While few and far between, one of the first birds that I picked out on the water last week was one of a few Cackling Geese in amongst the Canada Geese. While superficially similar, they really do stand out when sitting (or standing) near their larger cousins. In fact, it wasn’t until 2004 that the Cackling Goose was identified as its own species, with 4 subspecies identified.

The presence of a few duck species typically associated with prairie ponds and sloughs spending their time on the river is also another sure sign of a changing of the seasons. Both the Northern Pintail and Northern Shoveler were around in good numbers, but not too close. Even a single Tundra Swan flew down onto the river while we watched in awe.

Our first real good looks at the first migrant shorebirds to come through were along this stretch of river. These Killdeer are really quite hardy little birds. It’s no wonder they can be so numerous throughout the Calgary area!

In addition to the migrant waterfowl and shorebird species, there were also a couple of predatory birds around. A Merlin and Northern Goshawk made passes over us almost one right after the other, and we were treated to the disjointed yet beautiful song of this calling Northern Shrike for at least ten minutes before it was flushed by some dog walkers getting a bit too close.

Our first good looks at Herring Gulls this season were also along this stretch, many of which flew quite close to us, and in some cases, seemed to be just as curious about us as we were of them!

I mentioned Killdeer earlier, and we did come across a much larger group of them, but only thanks to the eagle eyes of Gus Yaki, which he had on loan from an eagle who decided to sleep in that day. Can you spot the Killdeer in this picture? (Hint: There are five Killdeer in this image.)

My first sighting of the next species of the day happened out on Vancouver Island over Christmas of 2013, and despite many trips out last spring in search of this species, and despite their relative abundance here in the spring migration, this was my first Eurasian Wigeon in Alberta. Again, a nice bird to see at the best of times. He seemed to be having a bit of a spat with his American relatives though…

We did also have a nice close look at a Redhead a bit further upstream, before things seemed to get a little bit too far off in the snow to get any good images, and yet, we did seem to have some Common Mergansers stalking us as we headed back up towards the start of our journey.

And that was it for our last week of the Winter Birding Course with the Friends of Fish Creek!

With the start of our Spring course next week, I’ll definitely be trying to not duplicate species that I get photos of each week, much like I tried to last year, with relatively good success.

Have a great week, and until next Monday, Good Birding

Lafarge Meadows – Spring has arrived!…?

Posted by Dan Arndt

March 20th, 2014 was the first day of spring. The Google Earth image that I’m using for this week’s map was from March 28, 2004, and seems to show much more open water on the Bow River, a bit of open water on both ponds at the park on the east side of the Bow River. It just goes to show how much colder, snowier, and icier this year has been (and continues to be!) than last.

Of course no visit to Lafarge Meadows and Sikome Lake is ever complete without a visit to the resident Great Horned Owls. With Dad on watch and Mom on the nest, it looks like they’re off to another good start this year. In fact, it won’t be too long now until the young start to poke their heads up and explore their new environment!

After a few weeks of them being more or less absent on the river, the Canada Goose numbers were back up as migrants began their trip north to their breeding grounds once again. This particular stretch of river is rather good for finding birds staging before their trek further north, or to disperse around the countryside near Calgary.

We were even lucky enough to see a (seemingly) early Mountain Bluebird along the river. While we only saw it at a distance, it was more than enough to be certain of the ID. Chances are good that this bird is finding enough to eat along the edge of the river with the various insects that are still present in the water, as well as egg sacs, larvae, and various other food sources near the banks of the river.

We ventured quite far south at Lafarge Meadows in hopes of finding some other birds a little bit closer to the water’s edge, but didn’t get anything much more interesting than the Mountain Bluebird until we headed back the other way. It all seemed to come fast and busy, with this adult Bald Eagle landing very close by to start, followed quickly by the sighting of some American Wigeon across the river, and then finding our first Killdeer of the season in amongst them!

Our last “new” birds of the day was a fly-by of a fairly sizeable flock of California Gulls, two of which flew by quite low, allowing for a much better view (and photos) than we had the previous week at Pearce Estate Park!

Exploring new trails at Shannon Terrace

Posted by Dan Arndt

Last week’s walk took us to Shannon Terrace in search of a Mountain Chickadee that had been seen there the week prior. The main trail between Bebo Grove and Shannon Terrace was washed out in the floods last summer, and so instead of doing the usual route walking between the two areas of the park and back again, we explored a few trails that are part of the Fish Creek Provincial Park Single Track bike way, much of which I haven’t explored by foot or by bike.

One of the most shocking things this time around was just how docile and downright tame the Boreal Chickadees were. Feeding from the tree stump feeding trays, from our hands a number of times, and flying out into the open. It may have had something to do with the temperatures being well above zero that kept them so actively feeding!

Aside from that though, things were about as one would expect on the west side of Fish Creek Park. We ran into a pair of Brown Creepers on one stretch of single-track but unfortunately I wasn’t able to snap any usable images of them. Moments later, we were nearly run into by some cyclists getting some of the intended use out of the single track, bombing down on us at full tilt. Can’t really blame them though. These particular trails were built for them!

We crossed the bridge and found a couple of Red Squirrels feeding on the left over seeds at one feeding station, and this particular fellow decided to pose nicely for us. Along this loop of trail we found a few more Boreal Chickadees, a few more Black-capped Chickadees, and not much else.

It wasn’t until we nearly reached the end of our walk when we had another flurry of activity nearby. A few Red-breasted Nuthatches were actively feeding on another feeding station log, while this male Downy Woodpecker tapped away on some nearby aspen.

At the western extent of our walk, just before turning back to head to the parking lot, a small flock of 75 Bohemian Waxwings flew by, chirping, cooing and calling in the air above us, giving us some of the better views our particular group has had of them so far this year!

Next week: Pearce Estate Park  and Prince’s Island Park, just outside of Calgary’s downtown core. Stay tuned, and good birding!

A Monday Two-fer: Bebo Grove (again!) and Carburn Park

Posted by Dan Arndt

The depths of the bitterly cold winter have finally subsided, and so I think it’s about time I get caught up on our last two outings.

Two weeks ago we headed to Bebo Grove in search of the Great Gray Owl, Barred Owl, and American Three-toed Woodpecker that had been seen there once again through the winter. We explored some of the back trails which I had never been on, but now that I know these areas exist, I’ll definitely be back, especially come summer!

Bebo Grove -

Bebo Grove – February 23, 2014

After a search where the Three-toed Woodpecker had been seen before, we moved deeper into Bebo Grove. As we crossed Fish Creek, this nearly adult Bald Eagle flew into the trees nearby, and was promptly mobbed by Black-capped Chickadees and a few Downy Woodpeckers before flying off once again.

It was cold. Bitterly cold. The birds seemed distant, and few and far between, but sometimes the lack of birds will draw attention to some of the other features worth photographing. These grasses were poking up through the water of one tributary stream to Fish Creek, and had accumulated a good coating of frost on them.

As we passed the area where the Great Gray Owl had been seen, we heard a single White-breasted Nuthatch singing away, and a little later, one of three Pileated Woodpeckers for the day flew by, and if we hadn’t turned at just the right time, we would have completely missed the fly-by.

As we walked through another area I’d never explored before in search of the Barred Owl, we came up empty once again, but of course I did find something to shoot. There’s no point spending three hours in -30 degree weather unless you get some images to take home with you! This stand of aspen looked like a black and white photo as it was, and I’m not sure what it is exactly, but I never get tired of seeing row after row of them.

From that point onward, things started getting busier and louder. Another pan through the grove where the Three-toed Woodpecker had turned up for others only turned up a Golden-crowned Kinglet, a few of both White-breasted and Red-breasted Nuthatches, and our only Hairy Woodpecker we found that day.

The following week, we visited Carburn Park. This was the first time since the floods last year that I’d really spent any appreciable time in Carburn Park, so it was really quite striking to see the damage that had been done.

Two weeks earlier, a Hermit Thrush had been seen here, but once again sub -30 temperatures kept the park quiet, and none of our attendees even came out, so Gus, Bob and I walked the park in a little over two hours.

The Bow River was full of life, much of which had only recently begun moving for the day. The Buffleheads were by far the most active of any of the birds on the river, diving again and again in search of food.

As before in Bebo Grove, when things slowed down in terms of wildlife activity, nature provided. Shooting across the river at the opposite bank, hoarfrost coated the willows and smaller bushes beautifully.

Very few birds were present as we headed away from the river, but this Northern Flicker posed, um, interestingly, showing us what it really thought of the bitter cold. I do like the detail and color in the shafts of the flight feathers and the wispy body feathers.

We even had to double-take when we began hallucinating and seeing mythical creatures, like this (very cold) unicorn Canada Goose.

One thing that really stood out all along the floodplain in Carburn Park was the height of the flood debris, once again completely covered in hoarfrost, at waist level, looking for all the world like little frozen bird nests.

And as we finished up our walk, we did find one of the local celebrities here in Carburn Park in the form of a small herd of White-tailed Deer. Not only were there a few very docile females, but there was also a pair of males, one with a well established rack of antlers, while the younger looked like a sad impersonation attempt.

Thanks for reading folks, and good birding! I’m very, very happy that the weather here in Calgary has made a significant turn for the better, and look forward to many migrants arriving in the coming weeks!

Backyard Saw-whets

Posted by Bob Lefebvre

There have been quite a few sightings of Northern Saw-whet Owls in and around Calgary this winter. Some of the sightings have been at night in back yards. The owls are probably looking for mice, which sometimes feed on seeds below bird feeders. Here is a link to a post about one seen in SE Calgary in December.

The owl below was photographed by Sarah Louise Lynch in Heritage Pointe, DeWinton, Alberta on February 20, 2014.

The owl below was seen at noon on February 9, 2014 in the St. Andrews Heights neighbourhood in NW Calgary. It was found by Dave and Susan Russum, who were led to investigate by a number of agitated chickadees and nuthatches in a spruce tree.

This is probably the same owl I had found in that neighbourhood three days previously. I had told Dave about it since it was only two blocks from his house, so they were on the lookout for it. When I found it, there were twenty-three magpies and seven chickadees mobbing the owl in a spruce tree. Whenever you see that many agitated birds in a mob, it is worth investigating. Sometimes they are mobbing a cat, but most often it is a bird of prey. I have found several owls and other raptors that way.

Another no owl day at Griffith Woods Park

Posted by Dan Arndt

Our walk this week returned to Griffith Woods, in search once again of the Great Gray Owl that had been a regular visitor there for well over a month now, as well as the Great Horned Owls and even a Northern Pygmy Owl that had been seen and heard there recently. The week got off to a good start, with Monday’s group having no trouble finding the Great Gray Owl, and the Tuesday group only missed it by a less than an hour before it flew off deeper into the dense spruce forest that are the hallmark of Griffith Woods.

The story throughout the day was that of distant birds and minimal photo opportunities, but I was very pleased that I was able to snap the shots that I did. When I downloaded my camera card at home, I found that I had only taken 31 shots in the course of the outing, so to have  a 25% “keep” rate I think is pretty good!

The first real opportunity came when we spotted a small flock of Bohemian Waxwings high up in a spruce tree, and I was able to capture a pair of them breaking off from the group showing their rufous undertail coverts and the bright lemon yellow on the tip of the tail feathers.

We hunted along the trail under the power lines for any sign of the Great Gray Owl that was our quarry, but the only evidence we were able to find of it was this hunting impression in the deep snow, showing the impression of the head and wings as the owl hunted one of many unfortunate voles that had become its dinner.

Never let it be said that I know everything there is to know about all of the parks we visit. This week’s surprise was the discovery of another small pond on the north-west end of Griffith Woods Park. All it really would have taken was for me to look at one of the many maps that I’ve published even here on this website to actually notice its presence, but thankfully Gus Yaki came to the rescue again and showed us where all the Canada Geese we had seen all morning were flying to. Also on this pond was a lone Common Goldeneye, and much to our surprise and delight was a solitary, and very uncharacteristically quiet, Blue Jay along the hedgerow behind one of the nearby houses.

Another nice surprise was a pair of Dark-eyed Juncos feeding underneath a spruce on the way back into the park after we had finished exploring the pond.

And then the wind picked up, and everything got quiet. While we retreated deeper into the wooded trails, the birds came fewer and further between, and only stayed in sight for mere moments at a time. Even our last species of the day, this Rough-legged Hawk, disappeared a few seconds after I spotted it soaring high above the nearby homes, but enough to positively identify it with its distinct dark wrist patches.

And so wraps up another week of the Friends of Fish Creek Winter Birding course. Next week we head back to Bebo Grove in search of last week’s quarry, the American Three-toed Woodpecker, along with another Great Gray Owl, a Barred Owl or three, and hopefully a Northern Saw-whet Owl!

Have a great week, and good birding!

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!

Birding Bebo Grove in the depths of winter

Posted by Dan Arndt

This week’s trip was unfortunately cut short as my lined cargo pants and a pair of thick long johns still weren’t enough to keep the bitter cold bite of the wind away. I wasn’t the only one though, my camera quit after little more than an hour of walking in what felt like -36 degrees C. This is the first time my Pentax K-5 has actually powered down due to the cold, and I’ve birded in colder actual temperatures, but it must have been the wind chill that got to the battery as well, and no amount of battery switching in the field would keep it working. I really only managed to snap off a few photos of a Black-capped Chickadee and a mass of floating ice crystals above the creek itself. I realized my camera (and my legs) would have no more of it when I attempted to take a photo of a Red-breasted Nuthatch we saw a bit further along on our route and I watched the screen fade, and them simply turn off.

Have no fear. I’ll make it up to you, dear reader, tomorrow, with some photos I’m sure you’ll enjoy!

Good birding!
