The photo taken shows this harrier is on the progress of moulting (T1)
The plumge of this new feather shows that it is not for pied harrier.
Circus spp. 1st cy winter may start its moulting of T1 from End/Nov~Feb or Mar.


As this harrier doesnt looks like adult female marsh harrier,
I guess this is a marsh harrier juv. (female)
whith a special plumge.


just for your reference.
