Any opinion about these presumed cachinnans

Hi all :
I think these 2 birds are ok for cach, but I´m not sufficiently experienced with this species ...

Thanks in advance...

both are 1st winter caspian gulls indeed, antonio. the first one has a slightly unusual scapular pattern (similar to some michahellis), but still looks good for cachinnans.

all the best,

Hi again:
Thanks a lot Lou.
By the way a returning bird has arrived to Asturias (Avilés). The 6º winter visiting Zeluán Estuary. (Daniel lópez Velasco).
Looks this is "Cachinnans time" here in N Spain.....
All the best.
