Perhaps I didn't word that correctly. Cats are more water averse and
can swim that distance if they decide it is really necessary. Foxes are
quite happy to swim and will do so on a regular basis. Even if there
was some disincentive to foxes, once one reaches the island then it is
likely to stay to cause greater havoc with the birds before overcoming
its disincentive to leave. I suspect overall there would be no advantage.

If the major problem is people then constructing islands
might help. If
it is foxes or cats then don't bother. Both can swim at
least 1 to 2 km
if they decide it is necessary. A few hundred metres (in an 18
hectare dam) is not even a barrier. Plus if the water level goes
down then the
distance becomes even less.
