This spring, Ottawa was visited by a number of rare birds. Do you ever wonder about what rare birds have been seen over the years? Rare Bird Detailed Records covering the OFNC Study area ( 50 Km radius of the Peace Tower, Ottawa) was last updated on October 31, 2020 and the information is now are available at Ottawa Annotated Checklist of Rare Birds Due to the widespread use of eBird and the near certainty that any rarity is documented there, updates have relied almost exclusively on the eBird database. Furthermore, currently no rare bird reports are available for any sightings after July 2015. The catalogue will be updated as they become available.
