Quite a while ago I was interested in feral animal spread and I found
quite a few reports of foxes swimming across rivers or to islands, not
so much in Australia as in other parts of the world. Plus it was
accepted that rivers posed no barrier to fox spread in Australia. At the
time I also came across a few eye witness reports of foxes swimming
across rivers with no obvious factor forcing them to swim.

Fox swimming team, there are still quite a few references to foxes being

Hi Andrew

I'm very interested - and hope you can let me know about the basis for
your cat and fox swimming distances?

The only info I have found on the web relating to such large distances

On the other hand, bird rafts have been very successful at places like
Hampstead Heath in London which has many foxes. Common Terns use them
as well as ducks etc.

I wish I had had time to try them in Australia.
