The first one, was a very pale/bleached bird, with coverts that match LBBG in color..... but head shape like YLLG




The second Gull was standing with some LBBG and YLLG, at first it seemed a pale YLLG, but then the long bill and pale base without pronounced gonys angle, make think of caspian, along with white neck and head.... but well marked coverts doesnt seem to fit cachinnans



best regards,
Rui
