Intermedius is rare in Israel, but it has to be siad that pale backed Lesser Black-backed Gulls may go unnoticed among the common heuglini in the region.
This bird originate from a breeding colony in N Norway, away from where heuglini breeds. It has a pale grey upperparts and in moult it shows what is known from 2nd winter intermedius. All secondaries and primaries are still 2nd generation and the tail is a mix of 3rd gen and 2x 2nd gen feathers (probably active rectrices moult, as only 9 out of 12 feathers are present; but such tail moult in late winter is known from intermedius - moreover, probably quite common). Note dark bill and overall brown not blackish wing-covert panel.
