Bird in active moult, with scaps replaced and now moult in the coverts and upper tertials. Would be interesting to see what will be the extent of this moult by May-June. New coverts overall still dark, but already it is clear this bird will develop barred covert patterns. And the scaps are not classic fuscus either (plain brown with simple dark shaft wedge); this bird has anchor patterns, like in many intermedius.
