Hello, the tail showed a faint and interrupted black terminal band, not so neat and thick like the one of michahellis.
This is a shot in flight. Poor quality, but the tail pattern and the inner primary flash are visible.

Hello, what do you think about them? as for the first one, I'm not sure if this could be a michahellis or LBBG. As for the second, i think it is a michahellis. The third one shows some characters intermediate between chachinnans and michahellis, what do you think? 1)https://www.flickr.com/photos/487...

Hello I took these (ugly) pics Yesterday on North west of Italy. On the field I noticed for White spots on the primaries and the bill showed a lighter Yellow tone at the base and for most part of it. The bill tipo was a brighter Yellow with a little red and black on it. https://www.flickr.com/photos...

I agree with GBBG.
