Mallard Hybrids Wild or feral ducks
Mallard hybrid, with "normal" Mallard inset for reference.
Red flanks.
Grey flanks and no white collar.
The white "bib" on the chest (above and below) often indicates a Mallard cross with a white domestic duck
of Mallard-type stock - and looks a little like the domestic "Duclair" white-bibbed breed.
The surprising feature here is not the male hybrid's bib or side but the dark female with patches of shiny green head.
Is this one just a juvenile male on the turn to adulthood?
Her ducklings don't have the conventional eye-stripe of Mallard ducklings.
Not a mallard bill.
New Zealand - wild.
Mallard hybrid possibly with NZ Black Teal (NZ Scaup)?
