The Third Ontario Breeding Bird Atlas begins in 2021.  The atlas is an incredibly ambitious endeavour and is only possible with the support of keen volunteers across Ontario.

Volunteers are being sought within the six counties that make up the Ottawa Region – parts of Renfrew, Lanark, Prescott-Russell, Stormont, Dundas and Glengarry, and Leeds and Grenville as well as all of Ottawa-Carleton.

Everyone who is interested in participating is invited to complete a short questionnaire available at: In addition to establishing a local database of participants, the questionnaire will help gauge interest, skill and level of commitment to identify and assign “principal atlassers” for each 10km x 10km atlas square.

For more information on the atlassing please visit  Breeding Bird Atlas.
