Bird Counts

The Hamilton Naturalists’ Club facilitates five types of bird counts: Christmas Bird Counts, West End of Lake Ontario KBA Survey, Lake Ontario Midwinter Waterfowl Census, Alan Wormington Fall Bird Count, and Dundas IBA Bird Surveys.

Christmas Bird Counts

The Hamilton CBC is held annually on December 26th (Boxing Day), and is one of the oldest CBCs in Canada, having begun in 1921. The Hamilton CBC covers a 7.5-mile (12 km) radius, centred at Dundurn Castle.

The Flamborough CBC began in 2021 and is held annually on December 30th. It covers the area between Hamilton and Guelph.

The Peach Tree CBC began in the 2015-2016 season and covers an area east of Hamilton that 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 exact calendar date on this count varies but tends to be in early January.
