it has features of both cachinnans and argentatus. so i guess this is what it is - a 'cactus' hybrid (btw., the most numerous hybrid combination among WP gulls).
Thank you! Which one of the characteristics is better for cachinans, the dark looking eye, more black on p10?

the long white tongues to outer primaries, especially the rectangular ending p10 tongue. that said, also some argentatus can show this, but in that case usually with even less black in wingtip, especially less black on p6. to complicate matters, even cachinnans can have a restricted p5 mark. and to me, bill shape plus yellow legs also indicate cachinnans parentage.
