Nature Calgary’s Bird Study Group coordinates bird species counts for the Christmas and May counts in the Calgary area. In cooperation with other birding associations in southern Alberta, we participate in counts from Bow Summit to Writing-on-Stone Provincial Park and also in Feederwatch.
See the upcoming species counts on our main birding page.

Alberta-wide results
Nature Alberta (formerly as the Federation of Alberta Naturalists or FAN) has compiled May Bird Count results since 1976, and those results were historically published in FAN journals. In more recent years, the Alberta results from 2006 to 2022 have been published on the Nature Alberta website.
