Mexican
Duck
(Anasdiazi)
Photographed in the wild, Naples, Florida Aug 2008
The widespread Mallard has given rise
to many populations around the world that have changed enough that they could
be considered separate species.
The "Mexican Duck" of
central Mexico and the extreme south-western United States and the Hawaiian
Duck both are closely related to the Mallard, and in both forms the male is
dull like the female. The Mexican Duck currently is considered a subspecies of
the Mallard, while the Hawaiian Duck is still given full species status.
