2021 Calgary Christmas Bird Count Results

Here are the preliminary results of the 70th annual Calgary Christmas Bird Count (CBC) which was held on December 19. Over 300 people participated this year – 136 field surveyors and 173 feeder watchers at 123 addresses. The current totals are 72 species (plus an additional two species seen during count week), and 75,917 individual birds.

(A previous version of this post had 326 field surveyors. That was an error, and the number has been corrected.)

These numbers are slightly higher than last year. The species total is higher than the long-term average of about 66. There are still some adjustments to be made to the numbers and the possibility of adding another species to the total.

For those interested in hearing all the details of this count, Matt Wallace will be speaking on the Nature Calgary Bird Study Group Zoom presentation on Wednesday January 12, along with the compilers of several of the other local CBC’s (and possibly even the Edmonton count!). Nature Calgary members should receive a link to this meeting by email. If you would like to become a Nature Calgary member, see this page.

Below is a more complete summary of the day, by Matt Wallace:

The 70th annual Calgary Christmas Bird Count took place on December 19. We had a highly successful year and I wanted to share the tentative numbers with you all.

Before jumping into the details I want to thank everyone who participated this year and acknowledge the outstanding efforts that were put in. The legacy and continuation of this count would not be possible without everyone’s contributions and appreciation for the natural world. Thank you to all of the participants and especially our section captains for accommodating the many new birders that joined in on the count. Thank you to TsuuT’ina Nation for allowing us the opportunity to visit your land on count day. I also want to give a special shout out to Lara Fitzpatrick and Bob Lefebvre for their superhuman coordination and data entry powers. They were both calm, cool, and enthusiastic about ensuring the collection of data and experience for participants was accessible and fun. Thank you to all!

Note: These are the tentative numbers (without adjustments) received on count day. 

Weather:

A relatively mild day for Calgary in December compared to previous years with temperatures in the -20s. Light winds (~10-15 km/hr) began in the afternoon.

Circle Sections and Participants

The Calgary Circle was divided into 38 sections this year. This is consistent with previous years as “subsections” were created for teams to survey within an official section of the circle. We now have an up-to-date digital map that includes all subsections. Participants were able to use the map in the field by saving it to their phone. This helped to ensure they were surveying within the circle boundaries and correct sections that they were assigned to. The Circle Section Map can be viewed here.

Participant numbers were strong with a total of 309 participants in total. There were a total of 123 Feeder Watcher residences with some households tag-teaming their yards throughout the day. On count day, a total of 136 people were in the field with many new birders joining the count for the first time. The number of field surveyors matches the average over the past 15 years (136). The field team hours were down from the record in 2020 (330) but we found more individual birds and more species than in 2020.

Birds Summary

This year we used two methods to obtain bird data from field teams. Participants could share their eBird checklist with an account we created specific for the CBC. Effort data, mammal sightings, and bird data (not submitted to eBird) were submitted by each section captain using the template.

All eBird checklists (98) shared during count day can be viewed in the  eBird Trip Report here.

Short-eared Owls in Winter

Short-eared Owls are scarce in the Calgary area in the winter, but sometimes a few can be found hunting meadow voles around fields that have not been cultivated for a few years. Ron Chiasson photographed these owls near Calgary this winter. Short-eared Owls are a sensitive species so we won’t give the location. They have declined in the Calgary area over the decades as native prairie has disappeared, but they have an almost worldwide distribution and their conservation status is “Least Concern.”

A hummingbird nest

Posted by Matthew Sim

Last year, I discovered a location in Fish Creek P.P. where I found 2 (and possibly all 3 species of hummingbirds that commonly occur in Calgary) nesting. In June, I had found a pair of Ruby-throated Hummingbirds and not long afterwards,  Hank Vanderpol and I discovered what appeared to be a female Calliope hummingbird sitting on a nest. A couple weeks later, a Nature Calgary field trip I led to the area discovered a Rufous hummingbird nest not far away.

This year, I was finally able to get out and search for the hummingbirds last week. It took me about an hour before I finally spotted a hummingbird moving about, but always returning close to me. That’s when I realized that this female Ruby-throated Hummingbird (for this is what it was), might have a nest nearby.

Sure enough, before very long, the female Ruby-throated Hummingbird had flown to her nest which had not been too far away from me the entire time.

At first the nest was tough to spot...

It was neat to watch the female as she sat on her nest, presumably incubating eggs. From time to time she would fly off but she was always alert and ready to defend her nest.

The most interesting part of watching this hummingbird though was the way she defended her nest from anything she perceived to be a threat, including a confused and startled Cedar Waxwing who twice made the mistake of landing too near the hummingbird’s nest. She swiftly drove the waxwing off despite the fact it probably wasn’t a threat; I suppose one can never be too cautious!

I will do my best to follow this nest in the coming weeks and see what comes of it. Hoping that the female will successfully raise her brood of young!

Leucistic Rough-legged Hawk

Posted by Matthew Sim

We’ve done posts here on this blog about leucism before, which is when a bird has reduced pigmentation, meaning it has more white in it’s feathers than normal for the species. We’ve had some examples before, including a leucistic House Finch, American Robin, Ruby-throated Hummingbird and others. For the past few months, Calgary has had a very neat leucistic bird in the area. This Rough-legged Hawk frequents the area around Highway 40, just west of Calgary.

Now compare this with a more normal Rough-legged Hawk.

A walk in the Weaselhead

Posted by Matthew Sim

While currently back in Houston, Texas, I spent a very enjoyable 2 weeks in Calgary over Christmas. Despite the cold (!), I got out a couple times, including an afternoon walk in the Weaselhead Natural area, taking photos of the local bird life as I walked.

A couple of Ravens announced their presence with distinctive loud croaks; as well as some more unfamiliar vocalizations.

Impressionism

 Posted by Matthew Sim

It was a bright, sunny winter afternoon in Calgary, nearly two years ago to the day. I had just retreated from a chilly walk around my neighborhood and was warming up when I happened to glance out the upstairs window. Upon doing so, I noticed a strange shape down on the snow. It took me a minute to figure it out, but once I realized what I was looking at, the story began to come together piece by piece. See what you come up with.

When you looked at this shot, you might have said that you see a bird’s impression in the snow. You would have been right. Now, you might have been a little more specific and described seeing a raptor’s impression. If you got this far, you did great. It’s not very easy to deduce much else. However, some may have gone even further, observing the shape of the raptor, comparing with descriptions in field guides and creating a list of possible suspects based on the fact that this was taken in Calgary, during the winter. If you came up with a few possible suspects, great work. But did you go any further?

If you did, you might have come up with a Sharp-shinned Hawk. You would be right. The wings are too rounded for Merlin or any other falcon, shape too small and body shape not to the right proportions of a buteo such as a Rough-legged or Red-tailed Hawk and the shape is once again far too small for either an eagle or a goshawk. Therefore it must be a Sharp-shinned Hawk. My neighborhood in Calgary has a healthy population of 4-6 Sharp-shinned Hawks so this make sense. From here, we can piece together a story,

Imagine a Sharp-shinned Hawk flying maybe 30-40 feet high, perhaps a little lower, circling at times. From its vantage, the raptor notices a small movement in the fresh snow below. Diving down, it attempts to nab a vole caught out in the open, plunging deep into the unmarked snow. Then what? Tough to say, and it will be a great mystery; we can only speculate at the final result but here is a breakdown of the photo.

I still wonder about the impression in the top right; what happened? Did the vole escape the hawk’s clutches the first time only to succumb to the second attempt? Did the hawk attempt to lift off without getting enough momentum the first go? Or was the impression in the corner caused  by snow falling off a tree limb?

It was quite interesting to see all the same, regardless of what the result was.

Sunday Showcase: More Starlings

Posted by Matthew Sim

This summer while I was up in Calgary, I noticed a lot of starlings as well, especially in Fish Creek P.P. On one of my excursions to the park, I positioned myself beneath a Starling’s nest hole and managed to capture a few shots as the bird descended to feed it’s young.

Preparing for landing…

Nooks and crannies; the process of saving seeds

Posted by Matthew Sim

I maintain bird feeders in my yard in Calgary all the time when I am around. Suet feeders, a tray feeder for millet, a peanut feeder, a niger feeder for siskins and goldfinches, a feeder for sunflower seeds; you name it. I enjoy watching the regular species of birds (and squirrels!) come in to eat and the occasional unusual species. When I watch “my” birds, I often notice intriguing behavior; the way that the Red-breasted Nuthatches stored food is particularly interesting. The nuthatches take a seed from the feeder, head to my fence and hide the seed there in a nook or cranny. Later, whether it be days, weeks or months, they would eventually come back looking for the seeds, providing some entertainment as we observe their antics.

Is it down here, perhaps?

Maybe if I come at it from this angle…

Certainly is amazing what you can see from your backyard!

Famous Birders: Gus Yaki

Posted by Matthew Sim

It has been a while since I last did a famous birders post but today, we have a very special expert birder and naturalist who some, if not most of us know personally; Gus Yaki.

Photo by Bob Lefebvre. Gus with an injured Ring-billed Gull.

Gus is a lifelong naturalist who has had a profound effect on numerous Calgarians, Albertans and people from across Canada and many other countries, including me. In November 2009, I was just starting to get seriously into birding and enjoying nature when I went on a Nature Calgary field trip to Fish Creek PP led by Gus; he did such a great job leading the trip that he helped to propel me into the world of birding.  Gus leads many trips throughout the year whether they be birding, botany or anything else dealing with nature, you can see some excursions that he will be leading for Nature Calgary in the near future  here.

Originally from North Battleford Saskatchewan, Gus used to walk 3 miles to school each day and got to learn and enjoy local fauna and flora this way. He started a nature tour service and, in 1983, led a trip around North America, following in the footsteps of Roger Peterson and James Fisher who had gone 30,000 miles around North America 30 years earlier. As Peterson’s and Fisher’s journey was immortalized in the book Wild America, so Gus’ trip was immortalized in the book, Looking for the Wild, written by Lyn Hancock, who was on the trip with Gus. Gus is very active in all conservation, birding and overall nature aspects of Calgary and, for me, is undoubtedly qualified as a famous birder.

Below are some questions I asked Gus about various aspects of his birding and natural life and his responses.

Note: Photos below courtesy of  http://www.stmu.ab.ca/

When did you become interested in birds and nature? 
I had nothing to do for nine months before I was born, so I listed all the bird sounds that I heard: as a result, I had a life-list (heard only) of 14 species when I took my first breath.
Seriously though, I don’t ever remember not being interested in birds and nature. One of my first teachers had a little 3 x 6 inch bird booklet. Walking almost three miles to school, I would see a bird on its nest. At school, during recess, I would thumb through this little publication to find a matching description. On the way home, I would confirm that I had correctly identified it.
Later, the CCF government provided a lending library service to those living in Saskatchewan, so I was able to borrow such books as Birds of Canada by P. A. Taverner, with illiustrations by Allan Brooks. Needless to say, I soaked up those illustrations and texts, so that when I saw the real thing, I was able to instantly identify it.
By then, I had realized that birds were only part of nature: they needed the other plant and animal species to provide food, shelter, and reproductive services – as did all other species, so naturally, I expanded my horizon accordingly.
You led birding tours; how many different countries have you visited while birding and what are some of your favorite countries to visit for experiencing nature?
Yes, I started my own nature tour company, “NATURE TRAVEL SERVICE” in 1972, and personally traveled to some 76 political entities. Places such as Antarctica and the Svalbard Islands (Spitzbergen) are not countries – thus entities. I did operate tours to additional destinations, which others led for me.
What were some of my favourites? I have been frequently asked that. I usually reply that it is the place that I am at that time. In terms of the most bang for the buck, I would have to reply that it would be East Africa – particularly Kenya and Tanzania. The masses of mammalian life was outstanding. On one trip, we saw at least 75 species of mammals. One day we recorded 34 species – some of them in the hundreds of thousands, and the total for the day was in excess of a million individuals. To put that into perspective, when I moved to Calgary in 1993, after going afield almost every day, it took me six months to see 34 mammal species – and usually only one of a kind at that.
On one four week trip to Kenya, we saw 618 species of birds – more than all the species ever reported as being seen in Canada.
Other notable destinations would include Australia, which has some 750 species – many belonging to totally different families than we have.
In late March, Israel was also spectacular, observing a million birds of prey and storks, etc., using the Great Rift Valley to migrate out of Africa, and then spreading throughout Asia and Eastern Europe.
South America is known as the Bird Continent, because it hosts over 3,000 species. This diversity is great – but the richest areas are in forests, and that makes it more difficult to see many of those species.
What has been one of your most memorable birding experience?
Apart from seeing the sights in Kenya and Israel, mentioned above, my most memorable sighting was of 17 Whooping Cranes that were migrating south on 20 Aug, 1946. At that time, supposedly there were only about 21 individuals of this species alive in the world. This small population’s nesting ground in Wood Buffalo National Park was then still unknown, not discovered until 1954. Most wintered at Aransas Nat. Wildlife Refuge in Texas.
The day before, 19Aug1946, I had witnessed 100,000+ Sandhill Cranes flying southward over me all day. The next day, the Sandhills again poured over me in similar numbers. Just before noon, a flock of about 20 low-flying Sandhills suddenly appeared immediately above the trees just at the north edge of the field where I was stooking sheaves of grain. Upon reaching the open sun-lit field, the Sandhills encountered a thermal and began to circle and rise up. As I watched them, I noted a flock of white birds, which I first assumed to be gulls, also circling to the NW of me. However, they soon ceased their circling, probably not having an effective thermal, and headed my way, ultimately joining the Sandhill Crane flock above me. The two species joined and circled together, ever gaining altitude – and eventually drifted off in a SSE direction. Both species were similar in same size and shape. The white birds had black primaries – and thus could only have been Whooping Cranes. When you plot a straight line from Wood Buffalo to Aransas, it takes you right over where I was watching these birds, about 35 miles, NNE of North Battleford, Saskatchewan.
People questioning me about this sighting have suggested that the white birds might have been American White Pelicans or Snow Geese. The fact that the two species where so similar, with neck outstretched and long trailing legs, totally rules out any species other than Whooping Cranes.
How many birds have you seen in your lifetime?
I have never counted the species, but I would estimate that I may have seen at least half of the currently recognized total of 10,000 species – thus about 5,000 species.
I never set out to observe as many species as I could – instead, I made sure that my participants could see all that was available at each destination. I repeately visited the same countries, etc., but had I made a point of visiting new ones each year, the total obviously would have been much greater.
How have bird populations changed from what you have seen throughout the years, especially those in Calgary?
Sadly, many species have had dramatic declines. I remember Point Pelee National Park in Ontario well. I first visited it one weekend in May1952, when we saw 1000 Wood Thrushes ahead of us on the road as we drove along. By the late 1990s, when I was spending up to three weeks there, we wouldn’t see a single thrush of any species. A similar story involves the wood warblers. I recall seeing 34 species of warblers (and other small birds in a single tree) at one time one day. Today, it might take you a full two weeks, scouring the entire park, to see all of them.
Re: Calgary, some of the raptors, especially Ospreys and Bald Eagles have increased in numbers, with the cessation of the use of DDT in Canada and USA. However, I noticed a big decline in Swainson’s Hawk numbers; initially we regularly saw 50 or more individuals when driving from Calgary to Canmore. About 15 years ago, their numbers dwindled down to five sightings. This was probably attributable to the insecticide used to kill grasshoppers in Argentina, the winter home of Swainson’s. In my early years here, some seven pairs of American Kestrels regularly nested at Inglewood Bird Sanctuary. Their numbers have now dropped to zero in most years.
Shortly after arriving in Calgary in 1993, I started a monthly walk along the Elbow River, from Stanley Park to the Glenmore Reservoir. Since then, at least 14 species of birds that were relatively regular breeders, such as Belted Kingfisher, Eastern Kingbird, Western Wood-Pewee, Ruby-crowned Kinglet, Baltimore Orioles, etc., have totally disappeared. Other abundant species, such as House Wrens and Yellow Warblers, have also greatly declined.
Where is your favorite location to bird in Calgary?
This varies with the season. In spring and autumn, the Glenmore Reservoir is host to many species of waterfowl. The White Spruce forests in the western end of Fish Creek Prov. Park, Weaselhead and Griffith Woods Park host a number of rarer passerines. The Bow River is a mecca to winter waterfowl, and attract many migrants and breeding species at other times of the year..
