Every December, people all over the world participate in a citizen science project called the Christmas Bird Count (CBC). This year’s Guelph CBC takes place on Sunday, December 20, 2026 and involves birders going out in teams in their assigned sections within a 24-kilometre diameter circle around the city. Each team identifies and counts as many birds as possible in a single day and results are compiled at a “tally rally” at the end of the day. The data is an important contribution to knowledge of wintering bird populations and how they are changing over time.
The CBC is a great way to participate in avian science, learn a little about the birds that spend their winters here in Guelph, spend time exploring Guelph’s various natural spaces, and make some new birder friends. People of all levels of experience are welcome to participate.
