I can see your thinking on this - assuming that you're thinking that what we have here are a couple of tertials and some secondaries, but if they're 9 cms long, surely they're too long? seeing as the bird is only about 12-13cms overall?Darrenom said:Ficedula hypoleuca would be my guess too André, given size and colouration.
But I know next to nothing really. I'm sure someone will be able to give you the bird's date and place of birth in due course.
Best wishes,
