Jim, your hybrid gull looks more like a Herring x Great Black-backed, if I am looking at the correct bird. The mantle color appears to be a dark gray (darker than the nearby Herrings), which would be more expected from a bird with Great Black-backed genes. A "Nelson's Gull" should as light or lighter in mantle color than a Herring.

One of highlights was a gull thought to be by Jym and John D a Nelson’s – a hybrid Glaucous x Herring Gull. Also present were 5 Glaucous Gulls, 1 Great Black-backed Gull and a Lesser Black-backed Gull. Other species present in the area, an American Kestrel and Horned Grebe. If I have something mislabeled, please let me know, thank you! It was a nice morning to be out among many other birders.
