A heron visited our pond last week and ate half the fish. The rest hid
and are
still looking very nervous. I had just removed the netting that
protected the
pond from falling leaves all winter. I would much prefer not to have to
net
the
pond all year round. Does anyone know of other, less unsightly but still
effective deterrents against herons?

I used to have a pond near a heronry and put fishing line at low level all
around the perimeter of the pond - I'd guess it was about 6" or 8" high.
The herons couldn't wade in and the fish are still there 6 years later.
Some 'cover' such as water plants helps the fish to hide, too.


I have used the same trick, but I used string, not fishing line, which is
much finer, more difficult to see, and very much stronger, since I wouldn't
want any birds to come to grief from getting it wrapped around them. I
*think* it worked, since visits from passing herons seemed to reduce, but,
of course, one can't be sure that the string was the real cause.
