I sent my earlier email before completing one sentence. It should have read
I have a clipping from a desk calendar on my office wall
which reads "The best way to solve problems is not to create them".

Subject: Pacific Black Duck - Mallard hybrids
Just a small addition to this discussion - particularly the record Nikolas
contributed:
I have undertaken close to 50 Atlas surveys at Warriewood (Sydney Northern
Beaches NSW) in recent years and while pure Mallards are occasionally on the
Warriewood Wetlands reserve and the settlement ponds, they seem to be much
more common and resident along Mullet Creek between the Wetlands and
Narrabeen Lagoon. These appear to be pure Mallards, generally paired.
There are of course plenty of Pacific Blacks on both the Wetlands and the
Creek so the opportunities for an enthusiastic Mallard Drake are plentiful!
I have certainly recorded what I considered to be good hybrids. Mind you
there are other mixed feral hybrids occasionally which could confuse the
issue (Muscovy, Chinese Whites, Khaki Campbell etc). They could certainly do
with a clean out.
Best to all

Hi all!
Although Mallards fortunately aren't that common in Australia, we can't be
too complacent about there presence. One thing I have noticed is that many
Mallards that I see on ornamental ponds are males (so definitely not a
population!), but since they are males they tend to get randy & if they
have nothing but black ducks to chase I am sure they would go after them.
So the chance of hybrids is quite high! All efforts should be made to
remove these birds, so they don't pollute the native ducks with their
genes!-Kevin Bartram
