Hi birders, This morning at 0817, Brandon Holden and I had a juv. candidate Glaucous-winged Gull flyby our position, just north of Grand Bend. The bird was flying south along the shoreline and did not stop. Kettle Point, Ipperwash, and Sarnia are places worth checking for it. Brandon managed a series of photos that will be posted shortly in our ebird checklist (https://ebird.org/canada/checklist/S75740084). Good birding, Ken Burrell kenneth.gd.burrell@gmail.com
