Hello,
At the structure, I would think YLG but I'm never so sure.

YLG. Tail says it all.

Thanks Lou, but what is it saying? Broad white band around the feathers?

sharply demarcated band, no black marks in the median part of outer rectrices.

A friend was wandering if this could be an atlantis because of the bicolor bill and overall darkness of the bird.
What do you think?
Thanks again for your help,

bill colour is of no use, often gets some pale tones in it and is extremely variable in all immature states. head striation is within michahellis (nominate) variation but not the usual type. to separate from atlantis (maybe canarian ones) we'd need to see more detail but tail pattern (rel. narrow black band) is not good for the canarian types which usually show a slightly broader band and are more patterned on median/basal parts of rectrices. however it does not look like the "real" atlantis from the azores which usually is much browner on underparts and head. most likely this is a nominate michahellis.

Not sure here. I think more pics are needed. Much black on the outermost rectrices requires some more study of the bird and it's not so typical of a ylg, but more for a LBBG, which could well sport a solid black band with no black marks on the white parts of the rectrices
