Especially in the video note hove long the primaries projects beyond tail compares to same aged argentatus nearby and please also note that the exposed primaries in the closed wing are jet black whereas argentatus has a more brown wash to it.
The juvenile plumage is quite worn and the moult is rather progressed compared to same aged argentatus with most of the mantle, lower scapulars, few wing coverts renewed. The advanced moult is classical in michahellis.
