Jan Baert asked for my opinion on this adult. It seems to show conflicting characters for any species and I couldn't really provide an answer. Maybe someone dares to say something? The ring was not read...

Michahellis is involved? (red on upper mandible, yellowish legs).
Grey tongue on P10 (long tongue, left wing) suggests something like argentatus or maybe cachinnans?

by the looks of it, yes. but we'll not be able to know it. this hybrid combo seems to be rare or at least there's little documentation about it.
some cachinnans have red on upper mandible during breeding time!

What a pity, that the ring-inscription ist unknown. But the Easteuropean rings have clips. But the ring looks quite large like Hiddensee (EA, size were better for GBBG). It is only speculation, but I guess to Lausitz origin.
