The more eyes we have looking for birds during the Calgary Christmas Bird Count on December 15th, the better picture we will have of winter bird populations in Calgary.

We could use a few more people to join existing teams who will be covering established routes driving or walking in a few parts of the city. (Refer to the section numbers on the map below.) This includes routes in the far NW (N9), Beaverdam Flats area (E1), Dover/Erin Woods/Forest Lawn/Marlborough neighbourhoods (E-5), the area south of Downtown along the Elbow River (W-3), a large section of the SW including North Glenmore Park (W-5), the large western edge of the Count Circle from Canada Olympic Park south to Griffiths Woods (W-6), and even Carburn Park (S-1) which is the section that usually finds the most species of birds. Please register if you’d like to help out in one of these areas – you can specify your preferred section number when you register.
Some sections have no one covering them at all yet. If you would like to do one of these by yourself, or lead a small team, again please register. Areas available include Bowness including Bowness Park (N1), The U of C grounds and parts of Varsity and Shouldice (N-4a), Parkdale and the rest of Shouldice (N-4b), and the Capitol Hill area (N-7 lower).
As always, in addition to the field teams, we will accept as many people as we can get counting birds at their feeders in their yards. You can watch for as little as 30 minutes on Count Day. Just select “Feeder Watcher” on the registration form under “How do you want to participate?” (Note that you must live within the Count Circle as shown on the map, in order that your Feeder Watcher results can count for the CBC.)
Once again, the count is Sunday December 15th.Register here!
Please register to take part in the field or at home
The Calgary CBC will be on Sunday December 15. We need birders to take part out in the field counting birds, as well as Feeder Watchers counting in their yards. All participants, whether new or returning birders, must register so we have up-to-date contact information, and, for Feeder Watchers, correct addresses.

Here is everything you need to know about the Christmas Bird Count, from organizer Matt Wallace:
I am inviting you to take part in the upcoming 2024 Calgary Christmas Bird Count (CBC) happening on December 15!
As you likely know, the CBC is the longest-running citizen science project which began in the year 1900 as a way to encourage people to appreciate birds while helping to conserve them through data collection. The Calgary event began in 1952 and is one of the largest CBC events in Western Canada with nearly 400 people participating annually.
Consider this event to be the annual census of our winter birds in Calgary! It requires lots of people and effort to conduct this event, so we are always looking for birders of all experiences and abilities to take part. We really aim to use this event as a way to build up our community of nature enthusiasts and would love for you to share the event information with your friends, family, colleagues, and community.
We have 38 circle sections and assign people to survey designated sections. All birds are identified and counted, and it usually runs the entire day depending on our participant’s availability. Bird submissions are made via eBird and shared with our CBC Compiler account. We also accept field templates from people who prefer to use them.We have section leaders who work with their groups to determine meeting locations, targeted areas, summarize effort data, and submit it back to our compilation team. We are looking for both field participants and field leaders (both returning and new).
Feeder Watchers (FWs):
People (individuals and families) observe birds visiting their yards and feeders for a minimum of 30 minutes on count day. FWs submit their data using a pre-formatted template which we provide. FWs are very important for our count as they help to fill in the data gaps where our field teams can’t access due to time or privacy. FWs must reside within the count circle, but we will confirm your address to ensure you are eligible to participate.
Data Entry/ Analysis:
Anyone interested in helping us to compile data is welcome! I often receive hundreds of emails with data templates, photos, and stories of the CBC. I manage but would love to have an assistant to help with this!
We continue to expand on our ways of showcasing the hard work of our volunteers. We have approximately 20 years of data (30 binders or so) which includes the detailed “section data” for the Calgary count. Yes, we submit all of the cumulative count “Circle” data to Audubon each year, but the section data is of interest to us on a local scale for showing how changes in our landscape and may influence bird populations.We would like to get all of this data entered prior to the 2024 count so that we can provide some additional infographics and analysis at the results presentation in January 2025.
In addition to the data entry, we would love anyone with skills in GIS and data visualization to join our compilation team in producing the final report (for media and the community).
So, all that’s left to do is register so I have your contact information, and we will be in touch soon! We look forward to you joining our CBC and thank you! Please feel free to contact me directly if you have any questions citynatureyyc@gmail.com.
Results of the January 1, 2024 Fish Creek Park Count.
Posted by Bob Lefebvre
The annual half-day bird count in Fish Creek Park was a lot of fun and a great success again this New Year’s Day. We had a high number of species, with high counts for several, and some new species for the count. It was another mild day, as it had been for pretty much the whole winter up to then.

This count is not an official Christmas Bird Count, but it has a pretty long history now, and it is an important tool to monitor the long-term population trends in the park. If you want to learn more about the count in all areas of the park, come to Birds & Beers this Thursday, February 8, where the Count Organizer Jim Washbrook will present the results and answer questions.
Results of the Calgary and Priddis Christmas Bird Counts will also be presented at Birds & Beers. In case you missed it, here are some of the results from the Calgary Count, showing the species recorded and the numbers of each:
Next Thursday, February 8th, we will have another Birds & Beers meeting in Calgary. As usual, we meet in the big ballroom at the Royal Canadian Legion at 9202 Horton Road SW. The event starts at 5 pm.

After some time for socializing, eating, and drinking, there will be a presentation on some of the recent Christmas Bird Counts that took place in the Calgary area. Matthew Wallace will present the results of the Calgary Count, Gavin McKinnon on the Priddis Count, and Jim Washbrook on the Fish Creek Park New Year’s Day Count. The presentation starts at about 7 pm.

Everyone is welcome at Birds & Beers! See you there!
We had really good results on the Calgary CBC on Sunday December 17. The weather was still very mild, and we had a lot of partcipation both in the field and at backyard feeders. The species total was 72, with an additional 2 Count Week species not seen on Count Day but seen on the three days before or after the count.

Below are the results as reported by Matt Wallace, the organizer of the count. First, watch a YouTube video with a quick summary. Next, the Summary Report has some details about the species counted on page one, and then a list of the birds on pages two and three. Just hover over the report and use the arrows at the bottom of the page to navigate there. Third, if you really want a lot of detail, and want to make your own graphs and so on, you can download the Results file. Finally, anyone can explore the eBird Trip Report, which includes all the checklists and photos submitted by our Field Teams.
_____________________________________________
From Matt:
Lara, Bob, and myself finally have all of the numbers tallied for the 72nd annual Calgary Christmas Bird Count! After a few days of enjoying the holidays ourselves, we’ve got the results ready for you to enjoy and explore!
Count Summary:
So, our total count this year was 35,833 birds! We had 72 species documented on count day with 2 more species found during count week. We added 3 new species to our 72 year list which included a Cassin’s Finch, Gray Catbird, and Western Grebe. Our “Count Week Birds” were a Yellow-rumped Warbler and Winter Wren.
Overall, our total bird count was way down from previous years but our species count was right on par with our 15-year average. Our low numbers are undoubtedly related to our low counts of Canada Goose, Mallard, and Bohemian Waxwings. It’s challenging to say exactly why this is but likely related to the warm temperatures we’ve experienced with very little ice on the river. When we have lots of ice on the river system there are few places for waterfowl to congregate. The Elbow and Bow do not freeze over entirely even in the coldest of winter so this is where they gather. When there is very little ice the birds are unlikely to congregate within the count circle. We heard little about dead birds from field teams this year but we know that avian flu has been a big issue the past few years. This may have contributed to our lower counts but really it is not clear at this time. As for our finches and waxwings, our numbers were below what we expected but again there is bountiful food for them currently in the boreal regions which again would not drive them towards or into our circle.
Overall, we are really pleased with how the count went this year despite having lower numbers of birds. We heard from lots of people that they enjoyed their day exploring new areas of the city and getting to meet new birders. We had 16 brand new birders (less than one year of birding) and 74 participants who had never taken part in a CBC before! We also had several participants that were participating for their third or fourth decade! Just amazing to see the age range (4-99 years), diversity of skill levels, and support that our Calgary birding community brings together! Thank you for all of your hard work and we should all celebrate what we accomplished as a community!
Below are some ways you can explore the results in further in detail:
1) Results Video: If you’d like a quick recap of the event you can now view the Results video on YouTube. https://youtu.be/EgwSl1iEp6Y (see above). Please feel free to share and we’d love for a few likes and subscribers! If you submitted some photos, you’re likely to find a mention. We also had to cherry-pick a few photos from our eBird Trip Report but have credited each photographer. If you’re still sitting on some photos or videos from count day, please send these along so we can use them in our results presentation in January.
2) Summary Report (.PDF): This is a brief summary of all of the bird and effort data we collected showing the final results and a few graphs of how far we’ve come over the years.
3) Bonus: Results Excel File: This is a detailed snapshot of our “behind the scenes” work which Lara has masterfully crafted for our count circle the past three years. Feel free to explore this at your own leisure if you’re a data nerd like us! This may be a bit more technical than some people would like but I figured a few people may be interested in seeing it anyways. Download the file to explore it.
A few tips for this file:
Use the tabs at the bottom of the page. There are really only a few tabs to be concerned with here (Graphs, Analysis, and Report). Look for any bold red text to help you understand how to investigate the data:
Graphs Tab:
In cells A3 (species) and A37 (Family) you can enter any species we’ve ever had on the Calgary count to produce immediate graphs. You must type the exact spelling of the species you would like to review. If your graphs are appearing empty, the spelling is likely off. If you are unsure of the spelling you can copy and paste the names of the birds found in the “Report” tab. You can then hover your mouse over the graphs to see the numbers for each year.
Analysis Tab:
In Row 7 you can use the drop down filters to explore things like News species, Record Highs, Record Lows, and comparisons between our yearly averages for each species.
Report Tab:
This tab is essentially what you see in the Summary Report File.
The 2024 Calgary CBC will take place on December 22, 2024! I’ve gone ahead and set up the registration form for next year in the case you wanted to register in advance. Just a note that this form will be online throughout the year so there is no rush to get it filled out. We will be sending out reminders and information September-December 2024. https://forms.gle/wBcfCRD4sqFpQ8qq9
One thing that isn’t displayed on our spreadsheets is the number of NEW birders/ participants we had this year (see comments above). This is one of the reasons why we are using a registration form – simply because we want to keep the CBC as accessible as possible!
We are working with Nature Calgary to organize a CBC 2023 event presentation in January and will send out an invitation to all 2023 participants to join the event and do a more in-depth analysis of our results this year!
You may also know that I assist with organizing other citizen science events throughout the year including the Calgary City Nature Challenge, Bioblitzes, Biodiversity Challenge, National Moth Week, and various other bird counts! Most of these are shared on my social media pages (@ CityNatureYYC) on Instagram, Twitter (X), and Facebook. If you’re keen on participating in other events, give these pages a follow so you’re up to date on what is happening around Calgary and Southern Alberta! I also reshare any photos or videos people post so if you’re out on your own, tag me and I’ll reshare your nature stuff!
Thank you very much to all participants and we look forward to having you back next year! I hope you all had a great time and are enjoying your holidays.
More Birders Needed For the Calgary Christmas Bird Count.
Many of our regulars are away or busy with other events this year, so we have a bit of a shortage of birders to help with the count, which is next Sunday. We can use experienced birders who could lead the effort in a section of the city, or help with a field team in a section. Even if you are a novice birder you can help assist a field team. The more eyes the better! Plus we are always looking for more people to count birds at their backyard feeders. That can take as little as 30 minutes.

You can register to participate in the count at this page. You may use this form even if you just want more information and may not take part this year. If you have any questions, you can email me at birdscalgary@gmail.com.
Thanks for helping out in this long-running Citizen Science project!
The Calgary CBC will take place on Sunday December 17. If you want to take part either as part of a Field Team or as a backyard Feeder Watcher, please fill out the registration form. People who particpated last year will have already received this by email. Please only register once!
CBC Coordinator Matthew Wallace has created a CBC2023 Registration Form for all participants to fill out. We know that it’s a bit of a pain to have to fill this out annually. However, it drastically reduces the number of emails Matt receives and helps him to keep all of the information better organized (and updated if there are changes to your contact information). Please feel free to share the form with anyone you know who may be interested in taking part! The form is for ALL participants (Field Teams and Feeder Watchers).
Note that to be a Feeder Watcher, recording birds in your yard, you have to live within the Count Circle, which does not include the entire city. We will inform you if you resgister as a Feeder Watcher and your address lies outside the circle.

Below is more information about the count from Matt Wallace:
Calgary Count Day: Sunday, December 17, 2023
As you know, we have two divisions for people to participate. Field Teams and Feeder Watchers. Both are critical roles for us to be able to get adequate coverage of the circle area. Below is a brief summary of the roles. I also want to thank both Lara Fitzpatrick and Bob Lefebvre for agreeing to assist with compilation of all of your data submissions!
Field Teams: Field Teams are composed of a circle Section Leader and section teams which help to survey a specific region of the circle. Leaders are generally carried forward from previous years but we often require a handful of NEW leaders to assist in circle areas which are unable to participate in any given year. The teams of volunteers communicate with their leaders to find out where they will survey. Sometimes this is as a group and other times teams are split up to cover their section. Each year we try our best to get everyone who has expressed interest in joining field teams out in the field and in an area of the city that they are interested in (BUT this is not always possible due to having too many people in one section and not others). Participants who are assigned to teams will be contacted by their Section Leaders to coordinate meeting locations or objectives (i.e. areas to search) in early December. Any late registrations will be offered spots where we are lacking participants. Trust me when I say we’ll do our best to get you in a zone that’s interesting but please have an open mind and be willing to travel if needed.
Field Team Data Submission: Once again, we are using eBird to submit our information: bird data (All birds identified and counted). Effort Data is collected by the section leaders for the entire team and is submitted via email using a template.
On the form this year I included a “Comments” section where you can express any interest in potentially being a new field leader.
Feeder Watchers:
FWs are responsible for counting birds at their properties on count day (Dec. 17). Feeder Watchers must reside or be participating at a residence within the count circle for us to be able to use the data. The minimum time required for counting birds is 30 minutes over the course of the day. This can be as a single session or broken up at various times throughout the day. Counting for longer than 30 minutes is encouraged! There is a specific methodology into how birds are counted as an FW. So if you register to be an FW, we will send out instructions into how this works prior to the count.
Feeder Watcher Data Submission: FW data is collected using templates and submitted back via email.
Count Week (December 14-20):
The CBC is essentially a census of all of the birds within our area. Occasionally, we can miss a couple rare birds so count week is an opportunity to scout locations and pick up any birds we may have missed. If you see any interesting birds during this period, please email me directly [citynatureyyc@gmail.com] so that we can include them as “Count Week” birds or notify section leaders to try and find them on count day!
I recently posted about the Calgary Christmas Bird Count, which is a week from today, on Sunday December 18th. Birders, like everyone else, have a lot of committments at this time of year, and we find ourselves a little short of help on some of the field routes. In particular, we need a few people who are good birders and also quite fit, who are able to do long walk through some difficult terrain. One such area is the Paskapoo Slopes near Canada Olympic Park, which has many deep ravines. Last year there was a Barred Owl at the west end of that area, but we missed it! We also need help in the Edgemont Ravines, and possibly in East Calgary at Elliston Park and area (Elliston is not as challenging of a walk). These are all good areas, so you might find something special!

If you are not up to a long difficult route, or are less experienced, you are still welcome to help out in the field. You will be placed on a team with experienced birders.
For those of you who can’t make it out in the field but watch birds in your yard, we will take as many Feeder Watchers as we can get! We are particularly short in the NE quadrant of the city. Feeder-Watching does not require a long time commitment and can be done in as little as fifteen minutes, or in intervals during the day. Of course, to take part you must live within the count circle.

If you would like to participate this year, or even if you just want more information or may want to take part next year, please fill out the registration form and we will be in contact with you.
Calgary’s Christmas Bird Count (CBC) takes place on Sunday December 18, 2022! CBC began in 1900 and is the world’s longest-running citizen science event. The count has been going on in Calgary since 1952 and is a valuable resource for understanding species and population trends of birds found in Calgary and around the world.
Matthew Wallace will once again be organizing the count and compiling the results. Lara Fitzpatrick and I will assist once again.
Please take a minute to fill out the Registration form here. Unless you are a Feeder Watcher who has already been assigned to a FW Captain, we are asking everyone to register, even if you have participated last year or in many past years. This helps to ensure we have the correct and most up-to-date contact information for each person and reduces the thousands of emails down to a more manageable size. It also helps Matthew to organize the required participant information that is submitted to Audubon and confirm that feeder watcher residences are within the count circle.

Completing the form will ensure that you will receive information that will follow in the next few days. The form is required for both feeder watchers and field participants. It can be shared with anyone who may wish to take part this year. Please share widely. If you are not sure that you can participate, or if you would like more information about the count, please fill out the form so we can contact you.

Count Week Birds: If you come across any interesting birds during count week (December 15-21), please send information to citynatureyyc@gmail.com including any notes, counts, or photos you may have.
The counting and correcting is done, and here are the final results of the 2021 Calgary Christmas Bird Count (CBC). I helped out with the Feeder watchers again this year. Matthew Wallace coordinated the count and finalized the results. Lara Fitzpatrick created the spreadsheets that organized the data. It was a fun learning experience for us, and many emails were exchanged and many hours spent in Zoom meetings.
First, watch this summary video of the count results presented by Matthew:
The 2021 count was held on Sunday December 19. The temperature ranged from about -13 C to -10 C, with some light snow and winds of 10 to 20 kph. So the conditions were pretty good.
We had good participation this year, with 136 people out in the field (pretty much as many as we could manage with Covid protocols and the number of leaders we had) and 177 Feeder Watchers counting in their yards at 125 addresses (we can definitely add more Feeder Watchers).

The final total on count day was 73 species, plus another four species seen during Count Week (December 16-22) but missed on Count Day. The total number of individual birds recorded was 71,468. (All numbers have been corrected to account for possible double-counting.)

The four Count Week birds were Varied Thrush (a continuing backyard bird that failed to show on Count Day), a Killdeer seen in Griffiths Wood Park, a Prairie Falcon seen in the east end on December 18th, and a Greater White-fronted Goose reported and photographed on the Elbow River at Sandy Beach, also on December 18.
Some of the notable birds this year were the two swan species and the Ruddy Duck (all continuing at Carburn Park), the three Sharp-tailed Grouse seen in the Tsuut’ina Nation in the SW, a Wilson’s Snipe and Snowy Owl at Carburn, a White-crowned Sparrow in the Weaselhead, and a Gyrfalcon.
We also had one species that had never been reported in the 69 previous Calgary counts – a Fox Sparrow in the yard of one of our Feeder watchers. This brings our cumulative total of all species reported on Calgary CBC’s to 143.

Matt Wallace, the count coordinator, has used the data to create some very interesting maps. (The maps below, and many more, will be posted on the Nature Calgary site when they are all complete.)
The Count Circle is divided into Sections, and here you can see how many species were found in each Section, and how the geography of the city influences species density.
Number of Species seen in each Section.
Due to the open water here, we get a lot of Mallards and Canada Geese overwintering. We also often have big flocks of Bohemian Waxwings in the winter. As a result, we tend to get really high numbers of total individual birds reported. This year, 71,468 individual birds were counted. This is one of the highest totals (and possibly the highest) of any of the CBC’s in Canada this year. It is far higher than the totals for the Edmonton or Toronto counts, for example.
Total number of individual birds seen in each Section.
Below is a map that shows all the Feeder Watcher addresses (the white dots). Some areas have quite a few, but we can definitely use more!
Distribution of Feeder Watcher addresses within the Count Circle.

It’s interesting to look at some individual species. Bald Eagles:
The 55 Bald Eagles reported on the Calgary CBC.

The Eagles are concentrated along the lower stretches of the Bow River, where they feed mostly on sick or injured Mallards.
Here is the Mallard map:
Mallards on the Calgary CBC.
Note how closely the Mallard distribution mirrors that of Bald Eagles. Mallards rest on the river, and go out to farmer’s fields to feed. There was also a huge concentration of 6,000 birds in the bit of open water at the northeast corner of Elliston Lake. Perhaps this is a safe place for them to rest, where there are fewer eagles around to prey on them than along the Bow.
The Canada Goose numbers were even higher than the Mallard numbers, with a similar distribution.
Canada Goose distribution on the Calgary CBC.
Black-billed Magpies are probably the most visible bird in Calgary, as they are found in all habitats and are very vocal. Many residents find them too aggressive and noisy to be likeable, but they are fascinating, beautiful, and intelligent birds. Like other urbanophiles (American Crows, House Sparrows, House Finches, and Rock Pigeons for example), they are doing very well in the urban environment.

The total number of Magpies reported on the CBC continues on a long-term upward climb:
As in the Magpie example above, we can use the CBC data to produce graphs of long-term trends of the overall results and of the numbers of individual species. The next graph shows that the number of participants and party-hours has steadily increased over time, as has the total number of birds recorded, but the number of species seen each year has plateaued.
The 73 species we had this year is the third-highest total ever, but it is line with a pretty flat graph since the mid-1980’s:
Below is an interesting graph that shows the number of Sharp-tailed Grouse reported. We had three this year, and three in 2016. But that’s it for the last twenty-plus years. They used to be found on Nose Hill and other areas at the city’s edge. But Nose Hill is now surrounded by development and the city has expanded to most edges of the Count Circle.

The results of the Calgary Count and several other nearby CBC’s were presented at the January meeting of Nature Calgary’s Bird Study Group. The meeting was recorded, and a replay will soon be available on the Nature Calgary site here.
The next Calgary CBC will be on Sunday December 18, 2022. If you haven’t taken part before and are interested in participating, either as a Field Observer or a Feeder Watcher, email me at birdscalgary[at]gmail.com.
Many thanks to Matt Wallace for all his hard work in organizing the count and producing the maps, to Lara Fitzpatrick, who created the spreadsheets that captured all the data, and to the photographers.
Here is a link to an article about the Calgary Count results on CBC news, including a video interview.
