Once again Calgary (and the nearby communities of Cochrane, Okotoks, Airdrie, and Chestermere, plus Glenbow Ranch Provincial Park) will be participating in the City Nature Challenge. From April 30 to May 3, anyone can participate in this fun, important, and fast-growing citizen-science project. People in hundreds of cities around the world will be photographing plants, birds, mammals, and anything else in nature to capture a record of worldwide urban biodiversity.

From the CNC 2021 Calgary Metropolitan Region website:

City Nature Challenge Calgary is back for the third year! Take photos of urban flora and fauna April 30-May 3 2021, then share to iNaturalist. Look for nature in your yards, neighborhoods, and local parks. Explore anywhere in Calgary, Cochrane, Okotoks, Airdrie, Chestermere, and Glenbow Ranch Provincial Park. Any photos taken April 30-May 3 and shared to iNaturalist before May 9 will be included.   Join the 2021 iNaturalist Project to Stay up to date!

So starting on Friday morning, take as many photos as you can of birds, plants, insects, and any other living things. You will have until May 9 to upload your photos to iNaturalist.
