Amending former hybrid listing to GLGU having received more feedback. White-winged Gull with limited contrast (anywhere) spotted by Cam coming to rest on the tip archipelago, then flying North up the West side ~8:30 Small and dark compared to the usual white beasts, but a GLGU notheless based on primary pattern (or lack thereof), and long bi-colored bill. Date isn't regionally significant but it is my earliest at PPNP. More research needed into identifying ssp. like nominate l. h. hyperboreus or even l. h. barrovianus which would constitute fairly rare occurrences of far flung birds.
