Hi all,
There is a nice 3-part article about wildfowl hybridisation by Christoph
Randler in Alula 2001 (issues 2, 3 & 4). And there the 'hybrid wildfowl
bible' by Gillham & Gillham.
Yes, there are Anas X Aythya hybrids. But I don't see Aythya traits in
this bird. I don't think that the bill speaks against the Mallard complex.
The wing pattern speaks for the Mallard complex and against Hardhead which
would show black-tipped white secondaries and primaries creating a
prominent and contrasting white wing stripe.
This bird looks to me like a 'barnyard-type' Pacific Black Duck x Mallard
hybrid.
Best wishes,
Nikolas
