Even if the secondaries were still growing this wouldn't affect the width of the dark trailing edge. I imagine in parks and zoo ponds hybridization is bound to happen and may the case here.
Twite.
We have very little hybridization in the zoo. I can only recall one Tufty hybrid TuftyxPochard male in all the years I am here. I think it looks pretty normal. Possibly the larger dark band on the secondaries tips looks exagerated because it appears to be eating into the white wing bar, due to its moult? Anyway I am not 100% sure so I will put it on the ID forum later and see what comes of it.
