The purpose of the mono-filament would be to get in the way of
the perfect perch that a railing provides. The birds can't
perch on it or the railing.

i dunno how well it would work, but it was an idea.
probably would need to be replaced once in a while, but
still cheaper than other options. another thing to do
could be to put dowels out from the railing to give
them a perch where they could poop into the grass away
from the deck. more work and expense than fishing line
but at least then you can still see them.

we have a few species that try to perch above my
patio door, which i discourage by pounding on the
wall to startle them away. sometimes they try to
build a nest up there too. i have chunks of wood to
put up there when that happens and they go away.
dunno why the builder didn't fill in that space to
begin with. a flat sill like that is just asking
for bird nesting.

i don't want to discourage the birds completely as
some of them come around and check the eves for hornets/
wasps or spiders and they are fun to watch as they perch
on the roof and look around.
