Greetings Fellow Birders, Please find the Ontario Rare Bird Report for the week of May 29, 2026 below. This weekly report provides information about bird sightings that are significant due to the species, the location and/or time of year of the sighting. Within these weekly reports, as much detail will be provided as possible regarding observations, including providing credit to the initial observer(s) and location details.
