Common / Ring-billed Gull in La Palma / Spain

Hi all,

Last month I found a Common Gull on a beach at Santa Cruz were was also the first Iceland Gull of La Palma, Canaries, Spain. However, despite confirmations of some birding contacts I have, Eduardo Garcia del Rey thinks it might actually be a Ring-billed Gull (he thought about an individual that wintered at Tenerife and trying to travel back to Nearctic).

I'd like your opinion. The photo with the Iceland Gull is "photoshopped", there were really together, but I took the photo of each separately (there were to far apart for my zoom) and joined them in post-treatment.

Thanks for helping

Alino

Welcome to Birdforum!

Looks like Common to me, the bill is too small for Ring-billed, and the bird overall too small compared to the LBBG in pic #3.

Thanks for your answer.

It is not a LBBG, it is Larus michahellis atlantis... they are dark indeed!

I see very pale mantle good for RbG... a bit confused now.

It does look small billed, but the body shape is all RBG - Common is realtively shorter legged and longer in the rear

When I found the bird, I thought RbG rarer than Common, so I hoped RgG... but what disturbed me for Ring-billed Gulll was: he was so short-legged and long winged that I doubted, and disappointingly came back thinking I "only" found a Common. Finally, Common would be new for La Palma, and RbG would be a second, not that bad of course.

I'm not arguing against you or Brian, obviously you have more knowledge of them... just explaining my confusion.
