Thank you for help.

A 3rd cy, moulting into 3rd winter.
A LBBG, judged on grey tone and colour.
Knowing the location we deal with either a out of route graellsii/ intermedius or heuglini.
The moult score is fine for Dutch LBBG.
The all-white tail and jumping replaced secondaries may well suggest heuglini, but nothing sure for now from my side.
The tone of the grey upperparts look a bit too blue for a Dutch/ English bird...

Thank you for your input, Theo.

Looks very much like a graellsii/intermedius. If 3cy heuglini can look like this, identification of 3cys is hopeless!

Thank you very much for your comment, Ruud. I don't have any experience with LBBGs, because this species is a rather rare vagrant, here in Romania. But some people familiar with this species told me the same thing - that it looks rather like a western type (graellsii/intermedius).
