Greetings Fellow Birders, Please find the Ontario Rare Bird Report for the week of April 17, 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. Please use eBird to provide specific details as sightings are recorded. Note that species in all-caps are on the OBRC Review List (http://www.ofo.ca/site/page/view/obrc.guidelines). Amendments/corrections may be sent to dbirkenbergs.birdreports@gmail.com. I thank each of you for your patience for any inadvertent oversights. As always, respectful feedback is welcome!
