Calgary Christmas Bird Count Results 2023

Dec31

72 species seen during a very successful count!

Posted by Bob Lefebvre birdscalgary@gmail.com

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.

Calgary-CBC-2023-Summary-Report

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.

4)  eBird Trip Report (Field Team Data submitted via eBird Only) 

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. 

Happy New Year!

Matt Wallace

Winter Birds Update, December 21

Dec23

Posted by Bob Lefebvre

In early December I posted about the start of Winter Birding season. As usual, we picked up almost all of the commonly-occcuring winter species pretty quickly for our list. Before last weekend’s Calgary Christmas Bird Count, we were at 87 species. But we added four new species on the Calgary Count on December 18 (Varied Thrush at Queen’s Park Cemetery, Northern Shoveler at Bonnybrook waste treatment plant on the Bow River, Gadwall at a couple of locations on the Bow, and a Common Grackle seen at a feeder in SE Calgary). So, as of December 20, we were at 91 species for the Calgary region.

The extreme cold weather we have been having is keeping birders from going out, and the birds are often sheltering, so one might think we would have a low number of species this year. But it is in line with the past few years:

YearTotal on Dec. 20Final Total
201989109
202098119
202192118
202291 ???

(Data courtesy of Caroline Lambert. Caroline has done most of the work on the Calgary list again this year, as well as maintaining the Bow Valley list.)

There are several other Christmas Bird Counts in the region in the next ten days, so we should get a few more species on those. (Nature Calgary’s site has some information on some of the other counts if you wish to take part. There are also some Long-term Foothills Counts that may need addditional participants.) And then there is the long stretch from the beginning of January to the end of February to find more species. So we might end up with a total of well over 100 species again.

Some of the species that haven’t been reported yet this year but that we are still likely to find include Wild Turkey, Northern Pygmy-Owl, and Short-eared Owl. Those have all been seen in the five previous winters. American Kestrel and Red-winged Blackbird have also been seen in each of the last five winters, but I wonder if it is now less likely at this point that they will turn up. We have a good chance to get Clark’s Nutcracker (seen in three of the past five years but known to winter in nearby areas) and Black-backed Woodpecker (seen in four of the past five). Hoary Redpolls have also been seen in four of five years, but the low numbers of Redpolls around this year will make it a real challenge.

If you see somethig that is not yet on the list, please report it on the Albertabird site.

Meanwhile, over in the Bow Valley near Canmore and Banff, they have 55 species so far. They may not get to the record of 74 for the season, but should have a respectable total in the 60’s. You can follow the Bow Valley Birding Group on Facebook here.

Check out the Alberta Winter Bird List site to see the lists for Calgary, the Bow Valley, Edmonton, and the overall Provincial list.

Winter Birding Season Is Here!

The winter birding season is from December 1 to February 28, and once again I will be helping Caroline Lambert to keep a list of species seen in the Calgary region during that time period. Caroline also maintains a list for the Bow Valley, while Gerry Fox keeps track of the Edmonton region list. Andy Ross compiles the Alberta provincial list.

All four lists, with some previous years’ lists for comparison, can be found on the page albertawinterbirds.org.

Already there have been 58 species reported on the Calgary list. We usually get between 100 and 120 species by the end of February, so there are plenty more out there to find. Have a look at the list and report your finds on Albertabird or eBird.

The Calgary Winter Birds List – One Week To Go

Feb19

Posted by Bob Lefebvre

For the past five years Caroline Lambert and I have been keeping track of all species reported in the Calgary region in the winter months (December 1 to February 28). This is something that Gerry Fox has done for the Edmonton birding community for many years. Caroline also keeps a list for the Bow Valley birding area in the Banff-Canmore area. There is also a long-standing list for the whole province that is maintained by Richard Klauke.

It’s interesting to see how many species and how many rarities we can find in the winter, and many birders like to keep a personal winter list so that they have incentive to get out during these slow birding months.

The Calgary region is the 80-km diameter circle that is also used for the May Species Count:

Here are the numbers of species we have recorded:

In the first two years we only accepted sightings that were posted to Albertabird but since then we have included any confirmed sightings we can get. So, although it is a small sample size, 110 to 120 species seems to be what we get in the winter.

We are currently at 113 species. The most recent additions, since January 15, are Red Crossbill, Purple Finch, Red-bellied Woodpecker, and Clark’s Nutcracker.

As always seems to happen when you keep a list, we have had some great rarities this year, but we have also missed on some species we usually get. But there is still a little over a week to go, so maybe we can find two or three more.

The three species that have been reported in all four previous years but not this year are American Kestrel, Harris’s Sparrow, and American Goldfinch. It seems a long shot that these will be found at this point, but it’s surprising that none have been seen.

Spruce Grouse is definitely a species we should be able to find. It was reported in three out of the four previous winters. Although their range is restricted to the western edge of the circle, there should be some around.

The other possibilities are the three local “hard-to-find” owls, Barred, Long-eared, and Boreal. And sometimes we get California Gulls or even Ring-billed before the end of February.

My personal winter list is now up to 44 species, which is still very low. I have only six species that are only or primarily seen in winter, plus a lot of resident birds and seasonal rarities. So I have nine days to go find Snowy Owls, Snow Buntings, Pine Grosbeaks, Northern Shrikes, and many others!

Here is a link to the page that Caroline maintains with all four winter lists. If you’ve seen any of the species that haven’t yet been reported this winter, let me know.

Previous posts on Albertabird about the 2021-2022 Calgary winter list:

December 2 – 41 species.

December 18 – 90 species.

January 15 – 109 species.

The Winter Bird Lists

Dec29

Posted by Bob Lefebvre

For many years Richard Klauke has maintained a list of bird species reported in Alberta during the winter birding season, December 1 to the end of February. This list shows us which species we can expect here every winter, which ones are not here every winter, and which ones are rarely seen in winter. It also allows us to monitor trends over time.

The Edmonton Nature Club has also maintained a winter list for their 80-km radius birding region for the past several years. A couple of years ago I started doing the same for our Calgary region, and Caroline Lambert has added a list for the Bow Valley birding area. Caroline has been maintaining a site where you can see all four lists, and she has been doing almost all of the updating of both the Calgary and Bow Valley lists this year.

Click here to see the Calgary Winter List. From that page you can navigate to the Alberta, Edmonton, and Bow Valley lists.

The Calgary list stands at 93 species. Last year’s total at the end of February was 100, and it was 103 the year before. It might seem like we’re getting close to those numbers, but it gets pretty hard to add new species from here on. Have a look at the lists and see if you know of any missing birds that were seen in each region. You can report your sightings on eBird or on Albertabird.

The Pacific Wren that was reported in Bowness in Calgary has been removed for now, since there is no agreement on whether it is a Pacific or a Winter Wren. It was seen and photographed several times, but no definitive conclusion has been reached, as far as I know.

Some recent additions to the list are Gyrfalcon (photographed in North Calgary on December 23), American Tree Sparrow (four birds seen at a feeder NW of Calgary on December 23, and seen and photographed again today), and American Kestrel (reported in the Strathcona neighbourhood on December 28).

New species for the three years the list has been maintained are Tundra Swan, White-winged Scoter, Eared Grebe, and Boreal Owl.

Notable species which were seen in the two previous winters but not reported yet this year (and which should be around somewhere) are Wild Turkey and Gray-crowned Rosy-Finch. Harris’s Sparrow has also not yet been reported, and there could be one lurking somewhere in the 20,000 square kilometers of our circle.

The Bow Valley List now stands at 54 species. Last year’s total was 67. No Gray-crowned Rosy-Finches have been seen here either, and surprisingly, no Great Horned Owl. If you see these, or any other species not listed yet, report it on eBird, Albertabird or to the Bow Valley Birding Facebook Group. The Bow Valley region is not a circle, so see the Winter Bird List page linked above to read the description of the area.

The Edmonton list is at 70 species. Although they have some excellent birds this year, they had a record year last winter, with 91. You can follow the progress of the Edmonton list on the ENC Nature Talk group.

Finally, the Alberta Winter Bird List is one you can contribute to from anywhere in the province. The total right now is 126, with 6 of those not confirmed. Last year was a record total of 166. This includes some subspecies that may not have been on the list in earlier years (or were not yet recognized as subspecies). The important thing is what hasn’t yet been seen. Of the 110 “core” species (seen every winter, or are elusive winter residents) only Wood Duck, Ruddy Duck, White-tailed Ptarmigan, Mourning Dove, Long-eared Owl, and possibly Cooper’s Hawk have not yet been reported in the province.

Have fun trying to add to these lists in your region!
