Try the plastic snakes on your boom too, to scare birds. It works...
Ill take temporary relief over nothing at all.

Bill, The boating community often recommends plastic snakes to keep
birds from roosting and pooping all over your boat. With over 30
years of boating experience in the San Diego California region I
witnessed lots of folks using plastic snakes. You can tell the new
guys at the yacht club by their new plastic snakes. Over time the
birds get used to the snakes and totally ignore them.
I know of no long term success with plastic snakes. Experienced
boaters I have known agreed that collectively we had never seen a long
term success using plastic snakes. Phony owls are also touted but
they too lose effectiveness fairly rapidly. I've seen birds perched
on the owls head pooping on it.
Geese and other birds have hearing that extends higher in freq than
normal humans. I say normal because in my mid 20's my left ear went
to 21,500 Hz and my right ear went to about 20,500 Hz. I could hear
bats feeding, ultrasonic alarms, etc. Now I wear $6000 hearing aids
from the VA thanks to small arms fire and other loud noises.
Something that works and doesn't lose efficacy from birds getting used
to it is ultrasonics used intermittently more or less randomly unless
used with IR motion detector or other detection apparatus. I have
used ultrasonics very successfully to keep away various pests
including birds. Places with large flocks of geese have nice lawns
"goose greased" so badly you can't walk through without getting your
shoes messed up. I have recommended ultrasonics to lakefront home
owners who had great success with repelling their Canada geese. The
geese soon learned to avoid that lawn and stay on his neighbors lawns
farther from the transducers. Word spread and some of his neighbors
went ultrasound also with great success. Only a few houses stayed
unprotected, a couple were only used a week or two a year, did not add
ultrasound (that I am aware of) but were partially protected by
neighbors with ultrasound.
Geese have pretty good ultrasonic hearing. To them bursts of high
levels of ultrasound is what having a steam whistle go off in our ear
is like. Some ultrasound pest repellent gear has selectable freq bands
so you can avoid bugging cats and dogs or include cats and dogs and
they will avoid the area too.
Decades back the lab where I worked had an oceanographic tower
anchored to the bottom of the ocean just off the coast from San
Diego. Seagulls used it for a big bird perch and pooped all over
everything on it. Seagulls were captured and "lightly tortured"
within limits of animal cruelty organizations and their distress cries
were recorded. These were played back at random intervals and worked
pretty good but over time lost effectiveness. You don't get used to
pain from powerful ultrasound, it always hurts if you can hear it.

Has anyone had a similar occurrence?
Around here (south central Oklahoma) the gophers are bad about
chewing up direct burial cables. Need to use conduit. They don't
seem to chew up PVC pipe/conduit. A notable exception is the direct
bury phone lines with which I have never had a problem.
Many folks don't appreciate the gooses bite. They can bite quite
hard and have a raspy insides to their mouths. They bite down hard
and then twist their heads. Pretty vicious.
