We were walking down the beach and I spotted a suspect plover, and watched and photographed it for a few minutes. Sarah Lamond caught up to me, and I showed her said plover. We both agreed it was a candidate for Common Ringed Plover, as the breastband looked extremely thick and eyering was not visible. The rest of the group soon joined us and we drew their attention to the animal. As we neared the plover, these characteristics as well as a narrow white supercilium became more apparent. The plover then flew with its comrades a little further down the extensive sand flat. On our way back, we made a concentrated effort to document this bird, which we succeeded in getting close to and noting down essentially every field mark relevant to Common Ringed Plover: white superciliary, black eye-ring, very broad breast band from several angles and poses, bright legs, auriculars same colour as mask (very dark). We then made a concentrated effort between Hayden and myself to acquire pictures of its toes. Several photographs taken from several angles indicated the lack of webbing on the outer toe, eliminating Semipalmated Plover entirely. An incredible bird for Ontario (2nd record) and more importantly, Algonquin Park.
