Breeding Bird Survey routes in Canada

The North American Breeding Bird Survey (BBS) is a continental roadside survey that relies on volunteer participation. There are about 1,000 BBS routes in Canada. Each roughly 40-km long route is made up of 50 stops where experienced observers identify and count all birds seen or heard in a 3-minute period. Once all 50 stops have been surveyed, the route is considered complete, or “run”. Roughly half of the BBS routes in Canada are run each year. Increasing the number of routes run in Canada is one of the best ways to improve the BBS.
