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!
