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!

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!

Winter in the Weaselhead

Posted by Dan Arndt

For the second week in a row, the weather cooperated with this past Sunday’s walk, giving us great light, good clear skies, and warm temperatures.

It’s always nice when we get chinooks here in Calgary, and today was no exception. Fewer layers make for a much more comfortable morning, and while we didn’t have the largest species count of the week, we arguably had the nicest day!

 

The Weaselhead - November 24, 2013

The Weaselhead – November 24, 2013

As you can probably tell from the map, the sightings were really concentrated between two areas of the Weaselhead. Near the parking lot at both the start and finish of our walk, and deep in the heart of the Weaselhead, concentrated primarily around a couple of special feeding stations.

I arrived about five minutes late for the Sunday walk, but it did allow me to capture a pair of species that didn’t really provide much in the way of good looks later on, so it was a bit of a blessing in disguise as this female House Finch inspected me as I was getting out of my vehicle, and just a short walk down the path while I was hoping to catch up with the group a Black-billed Magpie caught the light just perfectly to accentuate the iridescence normally hidden in its black feathers.

It didn’t take me long to catch up with the group, and we stopped at the usual spots along the pathway leading down into the valley, but the sound of this male Downy Woodpecker tap-tap-tapping on the trunk of this small willow caught our attention. I just love how the backlight of the early morning sun accentuates the red on the back of his head.

After watching a bit of a feeding frenzy by Black-capped Chickadees and a pair of White-breasted Nuthatches at one of the first feeders, the birds quieted down quite a bit on our walk. A Blue Jay gave us a flyover near the first bridge, doing one heck of a job impersonating a Bald Eagle’s screams, and a few flights of Bohemian Waxwings had us looking at the tree tops to spot them alighted, but sadly we would have to wait.

One particularly eagle-eyed observer did happen to spot this male Northern Flicker sitting stock still in a poplar. I still have no idea how she spotted it. Can you?

Once we re-entered the thick woods though, we were once again greeted by the ever-present Black-capped Chickadees and more than a few Red Squirrels came for a bite to eat as well.

While we waited at this spot for a good ten minutes trying to lure in a Boreal Chickadee, they were feeling rather shy today, with a pair of them coming in for a look at our group, make a few calls, and fly off again, despite my playing a few calls for them in an attempt to offer our group a half-decent look. For all our effort, only three or four of us got brief glimpses of them.

As we turned to leave the little grove, we stopped to check out a large flock of Bohemian Waxwings that flew in just as we were on our way out.

As we packed in our search for our target species and began the trek back to the parking lot, I couldn’t resist taking yet another photo of our enthusiastic group, as well as the habitat of the Weaselhead as well. These photos were taken in an area that six months previously had been the home to a good number of Calliope Hummingbirds, who are now enjoying the warm weather of Mexico and Central America.

As we reached the top of the hill on our trek back, we finally had our first raptor sighting, with this 3rd year Bald Eagle flying high over the Glenmore Reservoir and into the distance. I particularly like the fact that it decided to wheel around to the southwest of us, giving a very nice background to shoot as well. For those earth science nerds out there like me (or those inclined to mountain climbing), those peaks are Mt. Cornwall on the left, and Mt. Glasgow on the right.

It was also nice to get an overflight of Bohemian Waxwings (maybe even the same group I had shot earlier) as I was packing up my gear and putting it away in the jeep for the trip home.

Griffith Woods – New to me!

Posted by Dan Arndt

 

This week, the Friends of Fish Creek Birding course ventured out to Griffith Woods Park, on the southwest corner of the city. This was a new location for me, as my birding prior to September was limited to a handful of well traveled patches near the center of the city. After spending a few hours here last Sunday, I know that I’d be terribly remiss to not get out there again in the spring and summer.

It was, unfortunately, a relatively grey day, which lately has also meant fairly quiet in terms of both species and populations of birds, but we still got a couple new ones for our little group. As usual, I’ve posted the route we took on our little walk below, with the highlights noted in the captions.

Of course, the regulars were in attendance for the walk. The Canada Geese, which I’ve almost started to take for granted, were paddling up and down the Elbow River.

Common Redpolls were seen at the far east end of our walk, right at the beginning, along with an incredibly distant Blue Jay, which also alerted us to the presence of a Belted Kingfisher, which flew just a little too fast for me to get my camera up before it was gone.

About mid-way through our walk, Bob Lefebvre pointed out this beautiful little nest of one of the hummingbird species found in the Calgary area. Thankfully, nobody was home. (Special thanks to hand model Wayne Walker for presenting his world-famous hands for scale.)

On the far west end, while moving through a stand of very large white spruce, I was alerted to the sound of the Golden-crowned Kinglet. Not one, not two, but a flock of six(!) of them flitted amongst the trees while I wheeled and turned to get my lens on just one of them. Sadly, this was the best I got…

On our trip back, following the power lines that, for some reason were slated to cut directly through the center of the park, we heard the call of this male Pileated Woodpecker, who treated us to a wonderful series of aerial displays and a drumming serenade.

And that seemed like the end of the day for us… I was a little disappointed in the number of usable shots I was able to get on the walk, and the light was opening up just a touch, so I convinced Bob to walk back to try for another shot or two of the Belted Kingfisher. Sadly, though we heard it call at least twice, the only thing we were able to find were a whole bunch of rocks.

Wait… what’s that in the middle of the frame? When the Belted Kingfisher called for the last time before we left, we happened to spot two smaller birds with white on the underside of its primary flight feathers, which we thought might just have sounded like Killdeer.

Turns out, much to our surprise, we were right. Not one, but two Killdeer on the Elbow River at Griffith Woods. Hardy survivors of a relatively mild winter here in Calgary.

Definitely the highlight of the day was seeing this pair. It is unfortunate that the attendees of our walk didn’t get a chance to see them, but there will definitely be more of these little shorebirds around very soon!

Have a great weekend, and we’ll see you soon!

Birding at Bow Valley Ranch and Sikome Lake

This week marked the first of thirteen weeks of the Friends of Fish Creek Provincial Park birding course. Since its inception in the mid 2000s, it has swelled from a course run twice a week, to six times a week;  Monday, Tuesday, Thursday, Saturday, and twice on Sunday. This marks my first attempt at leading one of these courses, with Bob Lefebvre and I leading the Sunday morning group. Unfortunately, Bob wasn’t able to make it out this week, and so Gus Yaki led the group on Saturday, as usual, and I tagged along to be an extra pair of eyes and ears to assist him, and Gus also led on Sunday, breaking in the new Sunday attendees with his expert wit, grace, and knowledge.

On both days, we began at Bow Valley Ranch, and then proceeded southward to Sikome Lake and Hull’s Wood. There we stopped briefly near the parking lot before heading first the site of a Great Horned Owl nest that’s been used regularly for a dozen or so years, then to the Bow River, before turning back and returning to the vehicles, then home. Once again, I logged the route taken and have mapped it in Google Earth, in case anyone would like to re-create the walk again in the future.

At Bow Valley Ranch on Saturday, we spent about 45 minutes walking along the pathways, first stopping to find a pair of Great Horned Owls that were regular residents of the area.

We then stopped for a few minutes to watch for the Black-capped Chickadees and White-breasted Nuthatches that are all too familiar with what humans may have to offer them, and as such, came in nice and close for some very good views.

White-breasted Nuthatch

Just as we were about to head down to Sikome Lake, I heard the distinctive trill of White-winged Crossbills in flight, and so we spent some time trying to track them down. Unfortunately, they were on a mission, and continued on in short order, allowing only the briefest of views.

Sunday, on the other hand, was a much colder experience. We spent a little time trying to coax out the chickadees and nuthatches again, but they would have none of it. Instead, we searched around until once again, that old faithful pair of Great Horned Owls was found, and then headed southward shortly after.

Saturday was a great day on the Bow River. At the Sikome Lake parking lot, we were greeted by Downy Woodpeckers and Black-capped Chickadees, once again looking for a handout. Sunday was similar, but once again, in smaller numbers.

Another pair of Great Horned Owls are commonly found down here, and both Saturday and Sunday they did not disappoint. Saturday found them just east of their usual roost, atop a spruce tree near the main building at Sikome Lake, and Sunday found only one at that same building.

East to the Bow River we trekked. On Saturday, our travels were interspersed with a view of some Northern Flicker, as well as a single Killdeer, before reaching the Bow River, flush with Canada Geese, Mallards, Common Mergansers, Buffleheads and Common Goldeneye. After viewing them for a while in vain search of a Cinnamon Teal that had been sighted earlier in the week, we packed up and headed home.

Sunday though, we were trudging our way through the fresh snow only to be stopped by the gurgling trill of a nearby Bald Eagle. In fact, two of them were perched above a bend in the Bow River, though as our travels brought us closer, they flushed and headed northward.

Sunday also treated us to a view of an anomalous bird that had been spotted the previous day. A lone Lesser Scaup among the Canada Geese and Mallards near the Boat Launch at Hull’s Woods. After pausing to take a few photos and get a positive ID, we headed back to the vehicles.

I am definitely looking forward to assisting in this course, as many of our Sunday birders are eager to learn as much as we can teach them about the birds of Calgary and area, and I also look forward to watching the seasons change back to spring and experiencing the full extent of spring migration here in the frozen north of Calgary!

I hope you enjoyed these photos as much as I enjoyed taking them, and look forward to a new year of learning about these incredible animals with you all!

Christmas Bird Count

As a follow-up to Bob’s post on the Christmas Bird Count this year, I am posting from my experiences last year.

For the 2010 Big Year birding here in Calgary, I decided to participate in my first Christmas Bird Count. I had heard great stories about this annual winter event and I was not disappointed. I was scheduled to a very productive route on the Bow River, with Southland Park and Carburn Park our main birding spots. We had a very good turnout for species, recording about 29, if I remember correctly. Some of the highlights on our route, were Killdeer, a Northern Shrike, a Rough-legged Hawk, a pair of Great Horned Owls and two immature Trumpeter Swans. These swans were seen continually in January of 2011 and were identified as one immature Tundra Swan and one immature Trumpeter Swan.

A fellow bird-counter participating in the 2010 Calgary CBC

Overall, almost 200 people took part in the 2010 count, with 102 feeder-watchers and 92 birders in the field. Temperatures ranged from -15 to -13 degrees Celsius with some light snow falling in the morning. Birders in the field put in a combined
205 party-hours total, 230 km  on foot and 881 km by car. These stats were compiled by Phil Cram, Donna and Arthur Wieckowski, Bob Lefebvre and John McFaul and can be more extensively viewed  by following this link:

Bald Eagles are usually seen on the Bow River

My group divided ourselves up into small parties in the morning, scanning the Bow River on either sides in and around Southland Park. Once we had spent several hours scouring the snow-swept landscape for birds, we headed to the nearest Tim Hortons for some warmth, where we traded stories and identification tips over refreshments. We headed back out, this time to Carburn Park, where we added Bohemian Waxwings, the shrike and some Barrow’s Goldeneyes. We ate lunch in our heated cars at Carburn and spent the afternoon searching our range for any missing species. That evening, all CBC participants from all over the city flocked to the Flynn’s house where we were served delicious chili and shared our tales from the day.

Birds are not the only wildlife seen on the Christmas Bird Count

The 2010 Christmas Bird Count was very enjoyable; if you have never done it before I highly recommend it. Calgary is historically a very high count in North American for number of participants; last year we had a total of 194 participants which was the 7th highest count in the US and Canada (Edmonton was 1st in North America with 439 participants!!!). Calgary also had the most species of birds recorded on the CBC in Alberta with a grand total of 64.

I will be back in Calgary for the holidays and I hope to see you there!

Notes on Winter Birding

This, of course, is the coldest season of the year. Birding demands that you often stop and wait for the birds to show themselves. When standing still, you are not burning calories, therefore not generating heat. On stepping outside in the morning, some folks, thinking that it is relatively mild, decide to wear only a light jacket. After an hour they are chilled to the bone.

To fully enjoy this activity, you must wear enough clothing to keep comfortably warm. It is best to put on lots of layers. Wear a warm cap/hat/toque, for without a head covering you will lose a lot of heat. Be sure to wear warm footwear. If your hands and feet are still cold, it’s because you are losing vital body warmth. If you are cold, you just won’t be able to concentrate — and won’t enjoy the activity. Remember, the birds don’t care what you look like.

Some folks will want to bring a bird book, although the leader usually always has one with him/her.

If you are a note-taker, you may want to bring a notebook and pen(cil). Upon returning home, it is always a good idea to review the bird seen. After each field trip, we’ll also send you (by email), a listing of the species and the approximate numbers of individuals sighted.

A few rules for these or other birding outings

The purpose of these outing is to see birds. Birds are often best located by hearing them first. Try to limit your socializing to the parking lot. If you are busy chatting, the birds may not be heard. When they are found, some folks cannot even be made aware of their presence because of an ongoing conversation, so will miss out on seeing them altogether.

Unless you are the leader, do not walk ahead of the group. The leader often knows of the presence of a certain bird, but if you go ahead, you may flush it so that no one gets to see it.

Keep together! If the group is strung out, by the time the stragglers catch up, the bird may have flown. Also, if the leader wants to inform you of certain details he/she may tell those at hand and then repeat it when the stragglers arrive, or by then, other observations may distract, so the stragglers miss out entirely. Of course, the leader can wait until everyone is present, but that is wasted time for those who do politely stay together.

Shorter people out front! If you are tall, back off. Don’t block the view it’s hard to see through you unless someone blasts an opening.

About binoculars

Binoculars are a great aid in seeing the beauty of a bird. Once you are used to them, you’ll never leave home without them! I usually have a spare pair in case you forget yours.

Today, there are many kinds of binoculars, ranging in price from $29.00 to $2900.00.

Generally, beginning birders can get by with inexpensive ones. Once you’ve had some experience, you’ll have a better idea of your needs if you want to upgrade.

Binoculars come in many types. Basically they will be marked as 7 X 35, 7 X 42, 8 X 40 or 10 X 50. The first number is the magnification; in other words, they make the object appear to be 7, 8 or 10 times larger or nearer than that registered by your eyes.

The second number is the diameter in millimetres of the large or objective lens of the binoculars. The larger the number, the more light it admits. This may not be significant on a sunny day, but it will be very important on a dull overcast day, or at dawn and dusk.

Generally 7 or 8 power binoculars are ideal for most people. You will get stronger magnification from a 10 power but they usually are heavier. If you cannot hold them steady for long, you have to contend with a greater distortion due to hand vibration.

There are many small opera-type glasses available, such as 7 X 26. Some of these are extremely lightweight and can easily be held by children with small hands. However, as pointed out above, they are not very suitable in low-light conditions. A lens that is only 26mm across lets in only about 25% of the light admitted by a 50mm lens.

Binoculars are made so that one size fits all. However, since we are not all the same, they usually require three settings to match your personal measurements. You need to make these adjustments before using them. Normally you will never have to do so again (unless altered, as when you lend them to others, etc.).

1. Most binoculars have rubber or retractable eyecups. If you wear eyeglasses, fold down the rubber cups or retract the hoods. This will allow your eyes to get nearer to the lens, thus giving you a greater field of view.

2. The distance between people’s eyes vary. The two binocular barrels are hinged so that they can be pushed or pulled apart, to compensate for this difference. When using the binoculars, the barrels should be spaced so that the pupils of your eyes look precisely through the centre of the small lenses. When properly adjusted, your view should be through that of a perfect circle, rather than two overlapping ones. [Note that the top of the hinge has a calibrated dial showing the angle of adjustment. If you recall that setting, you can quickly reset them if someone else uses your binoculars].

3. On most binoculars the right eyepiece (in some models, it is the left one), is adjustable, slightly rotating, to accommodate any differences in your eyes. To adjust for your vision, close or block your right eye while looking through the left eyepiece. It is best to look at a sign, license plate or other flat image about 30 meters away. Between the two barrels there is a centre focusing-wheel or rocker arm. Slowly adjust the centre focusing until you have as sharp an image as possible. Once satisfied that it is perfectly clear, bring your binoculars down for about 30 seconds, to let your eyes rest. Next, looking at the same scene, using only your right eye, rotate the adjustable eyepiece until that image is sharp, too. Again, bring the glasses down. After 30 seconds, now looking through both eyes at the same time, you should have a perfectly sharp image. If not, repeat the above steps until satisfied. [Note that the right eye-piece has a + and - symbol, usually with a few dots between them. On the barrel below, there is usually a white dot. Remember these settings]. [Note, if the adjustable eyepiece is on the left, reverse the order of eye use above].

Once the above steps have been completed, merely rotating the centre wheel will quickly bring any object, near of far, into sharp focus.

After birding for some time, some observers find they are unable to obtain a sharp image. The adjustable eyepiece may have been altered accidentally, perhaps by rubbing against your clothing, etc. An elastic band over the eyepiece and the upper part of the barrel will prevent it from moving.

It could also be that your eye(s) are getting tired. By again following the above steps, you can readjust to sharpen the image.

Your next challenge will be to learn how to aim the binoculars at the correct angle so that you can quickly find the bird in the tree, etc. This takes some practice — but will come naturally with repeated use. Try locating different objects while at home.

While raising your binoculars, keep your eyes on the object. Don’t look down at the glasses while lifting them. Try to memorize the location of the bird by noting how the branches cross, etc. Once you are looking through the binoculars, in the approximate location, quickly focus them (by rotating the centre-wheel) and then search the area where you last saw the bird.

Most binoculars are supplied only with a narrow neck strap. The weight of the binoculars may give some folks a headache. There are a number of harnesses or wider straps that aid in relieving that condition.

If you have further questions, do not hesitate to contact me. In the meantime, I look forward to showing and sharing the birds with you on this upcoming activity.
