The Hamilton Naturalists’ Club has two types of bird counts annually, the Fall Bird Count, and the Christmas Bird Counts.
For the Christmas Bird Count (CBC), there are two: 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, we begun the new Peach Tree CBC, 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 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.
