Marsh harrier age (1 Viewer)

Well-known member
The upper parts of this male Marsh harrier struck me as being very unusual, at least to what i am used to see.
Still many brown feathers, yellow lesser coverts, yellow head, subterminal tail band. Yet the underparts look adult.
After some reading i think this could be a 3 CY bird.

Is this indeed correct?

Best regards,
