Very rare gull for Chequamegon Bay... This gull shows a hazy wash of dark gray throughout the face (not black), and lacks a clean cut contrast in the back of the head (Franklin's Gulls show a more solid edge between the dark head and pale neck). Note the dense/thick appearance of the white eye crescents. Also, this bird has a pale gray wash throughout the chest region, which is characteristic of non-adult Laughing Gulls. One of the most significant fields marks observed was the all-dark primaries on thsi bird. Franklin's Gulls should show some degree of white tips throughout the primaries, depending on age. Although a field mark observed better through photos, the bill on this bird is more elongated than a Franklin's Gulls' bill.
