Bird Counts

The Hamilton Naturalists’ Club facilitates in five types of bird counts: the Alan Wormington Fall Bird Count, the Christmas Bird Counts (CBCs), the Lake Ontario Midwinter Waterfowl Census, and Important Bird Area surveys.

We host two Christmas Bird Counts: the Hamilton CBC is held annually on December 26 (Boxing Day), and is one of the oldest CBCs in Canada, having begun in 1921. The Hamilton CBC covers a 7.5-mile radius circle, centred at Dundurn Castle. In early 2016, the Peach Tree CBC began, covering an area east of Hamilton, which includes the Lake Ontario shoreline at Grimsby south through the Niagara Escarpment continuing on through rural farms and woodlots all the way to Caistorville.

The Lake Ontario Midwinter Waterfowl Census (a.k.a, the “Duck Count”) takes place each January, counting the waterfowl and Bald Eagles of Lake Ontario. The next date is Sunday, January 6, 2019.

The West End of Lake Ontario (WELO) IBA Survey takes place on the second Saturday each month from January through April. This count has 17 areas ranging from West of Dixie Rd, Mississauga to Western Niagara-on-the-Lake.

The Dundas IBA Bird Surveys take place on a five-month schedule, covering the corridor of natural lands from Summit Muskeg through Dundas Valley to Cootes Paradise.

The Alan Wormington Fall Bird Count (FBC) is on the first Sunday in November each year, and encompasses the entirety of the Hamilton Study Area (HSA), at 25-mile radius circle from Dundurn Castle.
