Telling a juvenile Lesser Black-backed Gull from a Yellow-legged Gull is not always straightforward.
Although the fresh condition of the plumage in the picture advocates LBBG, one has to be aware  that some michahellis exhibit a surprisingly fresh plumage at the end of August with no sign of moult to 1st winter plumage. Presumably, these late moulting birds originate from the northern extreme of michahellis breeding range, where egg hatching date is later than in colonies around the Mediterranean.
In such a case identification should be based on as many features as possible: structural characters, brown tone of centres of upper-parts, coloration of under-parts, tail-pattern, pattern of inner hand and leg colour. See also the identification summary in the July Section.
