Thanks to all who responded. Two birds were involved going by head markings.

Head pattern was different. Ted Keyel and I felt it was two different birds.

Two adult Slaty-backed gulls concurrently appeared in SE WI this winter
not to distant from each other (Jefferson and Milwaukee Counties). Throw
in vagaries among cameras, settings lighting and angles, images seem
not to settle for me that they were in fact two different birds. So were
they dissimilar enough to ask if those seeing both were left believing
they were different individuals for certain?
Thanks,
Joe
