Such an unexpected and thrilling encounter with this mega-rarity - for us anyways, with just a handful of sightings ever recorded in Ontario, and mostly "only" juveniles. So an adult in peak breeding plumage no less - 5 minutes away from home, was such fun!! I spent about 45 minutes with it, and then it, along with the mega-common Ring-billeds, all got spooked by something, with the Sabine's not to be seen again. This is one of my favorites from the encounter, and when I noticed it was fairly tolerant of my presence I began a slow belly-crawl towards it...such a gorgeous bird - I think it's my new favorite gull species!
