Observation details

First state record, found first yesterday (1/15) by Kent Miller at the landfill and then unknowingly relocated in the evening by Matt Kappler at Summit Lake as it came in to roost. Roughly Herring Gull-sized with a dark slate gray back, obvious large white tertial crescent, dark smudge around the eye, relatively bright pinkish legs visible that were seen well through scope but unfortunately not in my photos, and a dark smudgy gonydeal spot on the lower mandible consistent with Kent’s photos from the original find at the landfill. When the bird flapped/raised its wings, there was limited black on the underside of the primaries, and the “string of pearls” along the primaries were noted. I obtained some poor but identifiable photos and video, and will post as soon as I can.
