Could it be a hybrid Common Gull x Ring-billed Gull?

Hi
I saw this gull few days ago. I'm wondering is it possible to be a hybrid with delawarensis. The eye is extreme pale, mirror on P9 looks like in RBG and bill is quite strong with nice black band.

Pale argentatus or hybrid?

Hi
Is it just leucistic bird or maybe some hybrid with Glaucous Gull?

adult bird with black marks on primaries

Hi
An interesting adult gull with some black on primaries. Pattern exclude hybrid but I heard that some young adult (4,5 CY) may look like this one. Unfortunately pics are very poor quality.
What do You think about this?
