Immature gull (probably 2. calendar year) in Sardinia (eastern coast, close to Golfo di Orosei) (1 Viewer)

[Paul Buntfuß]

Hello,
I continue to learn IDing gulls and found this immature one in the images from a trip to Sardinia in 2019. Images were taken mid April. I think the bird is in its second calendar year, based on the color and molt status (interpreted it as having still feathers from first plumage in the primaries). My guess would be Yellow-legged Gull (Larus michahellis), judging from the bright 'window' in the inner primaries which is but not so bright as it should be for European herring gull (Larus argentatus).
I'd be grateful for a check of the ID and especially for further hints on details by which this bird (and immature gulls in general) can be safely identified.

Best
Paul

Am wondering if this might be a 1st Winter Audouin’s Gull?

Cheers

1st Winter Audouin’s Gull?

Inner primaries, rump, tail all wrong.

yes, a 2cy Yellow-legged Gull it is. Already heavily bleached and worn but structure, very white underparts and contrasting and replaced inner lesser coverts, all correspond with L. michahellis (argentatus would be a mega in april, probably also during winter).

Thanks a lot!
