Birds of Elliston Lake

A little-known gem in the city is Elliston Lake, a stormwater pond at the east end of 17th Avenue SE.   It is the second-largest body of water (after Glenmore Reservoir) in Calgary.  At times it can harbour an impressive array of waterfowl, as well as some interesting mammals. (Click on pictures to enlarge them.)

When the Friends of Fish Creek group went there last Saturday, the lake was mostly frozen over, but there were still several thousand waterfowl on the few open areas.  (The northeast corner of the lake usually has some open water all winter.)

 The north half of Elliston Lake, looking west.

From 17th Avenue SE, turn south on 60th Street to access the parking lot.

The action actually started before we even got to the parking lot – a Merlin was feeding on a Rock Pigeon on the roadway.  I got a poor shot through the car windshield.

There was quite a bit of traffic, so it abandoned the pigeon and landed on a nearby pole.

A few minutes later we saw the Merlin attack a flock of pigeons above 17th Avenue.

Almost as soon as we started the circuit of the lake, someone spotted a Red Fox out on the ice.

Later, we saw the fox check the shoreline for disabled waterfowl, but it came up empty.

The birds didn’t seem to mind the fox much; they just moved away from the shore.

A close inspection of the masses of Canada Geese and Mallards turned up some interesting birds:

A juvenile Barrow’s Goldeneye (below, rear) is identified by having a steeper forehead and shorter bill than the Common Goldeneyes.

Many of the Canada Geese on the lake belonged to one of the small, short-necked subspecies, but there was one goose in among them that was smaller yet – only slightly bigger than a Mallard.  At first I thought it might be a Cackling Goose, but those are Mallard-sized and have a very stubby bill.  This goose (lower centre) is just a very small subspecies of Canada Goose.  Compare it to the Mallards just behind it.

Here is a Gadwall (rear):

There were a few Ring-necked Ducks:

Below are two Ring-necked Ducks (right foreground) with Lesser Scaup:

This Lesser Scaup landed on the ice and tried to walk back to the open water, but slipped…

…so he just gave up and sat down.

We also saw some Common Redpolls feeding on birch seeds:

Bird Profile: Bohemian Waxwing

A rush of wings, followed  instantly by  high-pitched trills break the silence. It is a cold, wintry scene, snow falling slowly from the never-ending sheet of clouds that blanket the sky in a gloomy grey. Standing still, nothing is to be heard; no cars, no people, and, above all, no birds. Just when it seems as though the entire world has gone into a peaceful slumber, the calm is broken by the sound of nature.

When they descend in hundreds, berries don’t last long at all. These birds are highly social and travel tight together, descending en masse on fruit bearing trees, where they proceed to rapidly consume thousands of berries. A very hardy bird, the Bohemian Waxwing toughs out the frigid winters of northern latitudes, enduring harsh conditions.The waxwing is both gregarious and elegant with a slick crest, and soft, silky plumage; it is deemed attractive by many. Named for the red, drop-shaped, waxlike tip on their feathers, this bird has warm grey-brown plumage, a black patch through the eye and a yellow-tipped tail. Bohemian Waxwings are berry aficionados and during winter, survive on the fruit of trees such as mountain ash and juniper, but also eat saskatoon and choke berries. Such a heavy reliance on one source of food can greatly affect a birds population and will cause much fluctuation. If there is a high population one year and a low fruit crop the same year, many waxwings will disperse in winter further south out of their regular mapped range. These years are known as irruptive years and are cherished by southern birders who do not usually get the opportunity to observe these birds.

I love witnessing large flocks of Bohemian Waxwings, it is possible to hear the whir of thousands of wings as they land, the twittering as they communicate endlessly, and the soft thud of berries as the fruit falls into the snow below, dropped by  a careless tug from the beak of a waxwing. Sometimes, after the flock has left, the snow will be littered with bright red berries. Then as cars and people pass over the fruit, the snow will be stained a rose color, evidence of the masses of birds that banqueted there.

Remember next time you are shoveling snow in -30 degree weather; you are privileged in that you can witness this elegant species brightening up the dull grey day. These birds are truly northern and hardly extend into the U.S. They are definitely one of the things I will miss most about Calgary winters.

Join Project Feeder Watch

Backyard birdwatchers across Canada are invited to take part in the 25th season of Project FeederWatch, from November 12 through April 6. With each season, FeederWatch increases in importance as a unique and indispensable monitoring tool for more than 100 bird species that winter in North America. Last year, over 2,500 Canadians and 11,000 Americans counted backyard birds; their observations help scientists better understand the health and behavior of birds – an important indicator species for the well being of our planet.

Each checklist submitted by ‘FeederWatchers’ helps scientists at Bird Studies Canada and the Cornell Lab of Ornithology learn more about where birds are, how they are doing, and how to protect them. Participating in Project FeederWatch is a great way for families and friends to connect with nature, have fun, and help birds. You do not have to be an expert to participate – they’ll send you a poster of common birds, and help is just a phone call or email away.

Participants choose how much time they want to dedicate to the project. They are asked to select their own two-day count period once every two weeks, and then count for as little as 15 minutes (or as long as they like) on one or both of those days. Sightings are entered online at www.birdscanada.org/volunteer/pfw or reported on paper data forms and mailed in at the end of the season.

Data from FeederWatchers have helped scientists learn about changes in the distribution and abundance of feeder birds over time, expansions and contractions in their winter ranges, the spread of disease in bird populations, and the kinds of habitats and foods that attract birds.

Loon Survey, Part Three

It’s high time I updated the Loon Survey I did for Bird Studies Canada this past summer. You can read about the survey, and see pictures of the eggs, fledglings, and adult loons, on my previous posts: Loon Survey, Part One, and Loon Survey, Part Two.

In late August I returned to Leisure Lake, near Bragg Creek, to check on the Common Loon family.  The purpose of the third visit, late in the season, is to see if the young loons have survived.  Like all birds, loons have a high rate of mortality among fledglings.

I was happy to find that the two young, still in their brown plumage, were doing well.  They were starting to look like adults. (Click on any picture to enlarge it.)

  Juvenile Common Loon, about two months old.

The two juveniles with an adult.

However, despite making a long slow circuit of the entire lake, I only saw one of the parent loons.  I thought that perhaps one of the adults was hiding on shore somewhere, but I’ve been told that loons are so ungainly on land that they only go ashore to incubate their eggs.  It’s possible that it was in the reeds somewhere and I missed it, but that seems unlikely.  Perhaps one of the adults departed for the wintering grounds earlier than the other adult and the young.  I don’t know if they normally do that or if they all leave together.  The other possibility is that the missing adult succumbed to disease or a predator.  It will be interesting to see what happens there next spring.

If you want to participate in the Canadian Lakes Loon Survey, there are plenty of unmonitored lakes with loons on them.  Contact Bird Studies Canada for more information.  Here is a link to the Canadian Lakes Loon Survey page.

Revering a Raptor

From the day that I first laid eyes on the species, gliding on broad wings over a coniferous forest in the Rocky mountains of Alberta, I have always looked with awe at it, astounded by its sheer magnificence. Many people have soft spots for raptors. I have a soft spot for one in particular: the Northern Goshawk.

I first saw a goshawk just over a year ago. It was early October 2010, and I had signed up for the Mount Lorette Golden Eagle field trip with Nature Calgary. I went out on my own to explore the area right around the location of the watch, and, while out on the path, witnessed an adult goshawk rise up from the spruce trees and circle away. From that moment on I was always looking for goshawks; every chance I got, I would go searching for them.

Rising up out of the forest; my first views of a Northern Goshawk

Several days later, on a biking trip to Fish Creek Provincial Park, I came across an adult Goshawk perched high up in a poplar, sitting and gazing at the world around him. I stood and watched this magnificent raptor for more than half an hour, pointing the bird out to anybody who came near. Many of these were joggers or were merely walking their dogs. They took little interest in this bird, that is somewhat tricky to spot in the city of Calgary. I was rewarded though by the few who did pause to look up at the goshawk and comment on his size.

“What did you say it was called?”

“A Northern Goshawk”, I would reply eagerly, ” it’s somewhat unusual here in Calgary.”

“Really? Wow! Look at how big he his!” After staring up at him for several more seconds, they would smile and move on. Hopefully the Goshawk had made an impression on them though.

While I watched this large, strong accipter (agile, forest dwelling hawks with short rounded wings and long tails) it scratched its head withs its talon, giving me glimpses of those wicked sharp utensils it uses to tear apart its prey. Eventually, it lifted off and disappeared amongst the trees.

Goshawks are among the largest, strongest and most audacious of the hawks of North America. In November 2010, a little over a month since I first observed this species, I got an excellent opportunity to view this audacity. I was riding my bike home from Fish Creek and was running slightly late. I looked down for a moment as I pulled onto a dirt path going around a storm water pond, and, when I looked up again, there, sitting merely yards away from me in a small tree no taller than 10 feet, was an adult goshawk. They now seemed to be everywhere I went! I slammed on the brakes as hard as I could and screeched to a stop, panting breathlessly. Pulling out my camera, I marveled at how close this bird had let me get. I stood watching him, he stood watching me, this went on for several minutes before he abruptly flew away.

Taken with a 200mm lens and no crop; I could see every detail in the feathers

Instead of leaving altogether though, the goshawk started hovering over a field, pulled up, started hovering again and then pulled up once more. Then, with a sharp turn, he came whizzing right at me and flew by me at a distance of about 4 feet! The raptor was so close that my lens couldn’t focus on it!

These incredibly neat personal experiences combined with an amazingly beautiful species, have come to make me love the Northern Goshawk.

Nothing But Shoreline

The irrigation canal in southeast Calgary is drained in late September, and as the water level drops, it exposes lush shorelines with plenty for the birds to eat.  From mid-September to freeze-up is the time to get out to look for waterfowl, gulls, and late migrating shorebirds.

Fall colours reflected in the remaining water

I usually explore the sections from the canal headworks near the Max Bell Arena to south of 50 Avenue SE.  There are four parking areas, and you can go up and down a portion of the canal from each one.  It’s a long walk to do it all at once, but a fairly short bike ride.

Click to enlarge the map.

Max Bell Arena:  Access from Barlow Trail SE, just south of Memorial Drive.  There is a large parking lot north of the arena, and you can walk down to the canal headworks from there, and walk along the east bank.  If you want to get to the west bank, you have to cross over at the 17 Avenue SE bridge.

Bow Waters Canoe Club:   Access is off 26 Street SE, just south of 17 Avenue.  Cross the bridge to get to the paths on the west side.  The path on the east side between here and Gosling Way has some steep, difficult terrain, and it is almost impassable by bike.  This lot is fairly secluded and I don’t like to leave my vehicle there.  I prefer Max Bell or Gosling Way.

Gosling Way:  Go west off 26 Street SE at 34 Avenue.  This is the road that goes to the Inglewood Golf and Curling Club.  The parking lot, used by off-leash dog walkers, is just west of the bridge over Deerfoot trail, on the south side of Gosling Way.  It only holds about ten vehicles.  From this lot, walk down to the bridge over the canal and take the paths from there.  In the winter, you can also park at the golf and curling club, but it is a bit of a walk back to the canal.

50 Avenue SE:  It is difficult to park here.  There are only two small spots, each with room for two cars,  at the east end of the bridge over the canal.  It can also be a very busy road, so I avoid parking here as well, and usually just walk from Gosling Way.

The canal has a paved path on one side (sometimes on the east, sometimes on the west) and a dirt or gravel path of sorts on the other side.  I like to go on the east side in the mornings and on the west side in the afternoons, to keep the sun behind me.  This late in the year, the water is usually frozen in the mornings, so there are few birds around.  But on warm afternoons the ice melts, and the birds arrive.

Pat and I have each posted about birding the canal before.  You can see Pat’s post here, and my post here.

Lately I’ve seen quite a few Canada Geese, Mallards, and Ring-billed Gulls, and a few Hooded Mergansers, Common Goldeneyes, and Greater Yellowlegs.  In past years I’ve seen Redheads, Blue-winged Teal, Killdeer, Long-billed Dowitchers, and Rusty Blackbirds all feeding along the shorelines.
