[CQ-Contest] HELP! Too many birds roosting on my antenna system !

[N6KI Dennis Vernacchia]

HELP !

    I now have a serious problem with dozens of small birds that for the 
past year only
have decided to roost on my 94 ft high 80 mtr antenna. They are pooping 
all over my yard
and now the neighbor on east side is getting bird droppings in his 
swimming pool etc.
and into his yard area if the prevailing wind from west is blowing.
If you go to QRZ.com you can see pix of my antenna system when you look 
up my call.

I have a fake owl at top of mast and another owl at 22ft below on my Yagi.
For years the fake owls seemed to keep most birds away.
These are small birds with a long shrill type of cry.
Any idea how I am going to get them to leave permanently???

For years they would only stop by and perch for a few days a couple 
times a year,
I assume coming and going somewhere but now they are permanent the past 
year it seems.
I guess that means they built their nests somewhere nearby and that the 
local owls have not
driven them off or attacked their nests ( or they owls can not get to 
their nests. )

Any advice appreciated !!

I thought of trying to buy one of those billboard things that looks like 
a dipole and rotates but not
sure I can adapt it to my mast system
