Breeding Bird Atlas 3

Data collection for the Ontario Breeding Bird Atlas 3 (Atlas-3) started January 1, 2021. Volunteer birders will count and record the presence of breeding birds across Ontario through 2025. The two previous Ontario atlasses ran from 1981–1985 and 2001–2005, followed by the publication of books summarizing the results. We’re hoping Atlas-3 will be the best one yet – providing an unprecedented understanding of the status, distribution and abundance of the province’s birds and a huge database of information that can be used for bird conservation purposes well into the future.

Volunteers are at the absolute heart of an atlas and are essential to the success of Atlas-3. Birders of all skill levels are needed, especially those with the ability to bird by ear. Interested in helping with the Atlas but unsure how you can contribute? Check out the FAQ or contact the atlas office for more information.
