I never found a good solution to roosting birds except turning the beam
frequently to get the turkey buzzards to leave just as soon as they started
using the TH-7 boom and driven element. 1 KW CW on 20 M may have also
helped. I also had several Great Gray owls using the TH-7 at 50' at night,
leaving small animal carcasses and the pellets of owl dung at the tower
base. When I recently took the the TH-7 and Rohn 45-G down after
twenty-seven years in the air, the corrosive effects of bird dung was
evident; stainless steel was corroded and galvanized steel was etched and
beginning to rust. Red tailed hawks do keep the other birds away and may
have the least negative impact on your aerial equipment as a result.

Years ago, where I grew up, there was a problem with starlings roosting in
trees on one block. Talk about a racket!! Someone came up with a solution:
Let's have the Police Dept get a case of bird shot for the 12 ga. shotguns.
Then, one evening at the appointed hour, they assembled all the squads AND
the fire rigs on the block. The "fired up" all the sirens and the shotguns
were fired in the air, but not at the birds, until they were out of ammo.
"We'll just scare 'em away with noise" Naturally, the birds all took off.
Everyone patted themselves on the back, packed up, and left. If I remember
correctly, the last squad had barely rounded the corner and the birds
started coming back.
Now on the other hand, at work we had a tower and a massive LPDA on the roof
for HF emergency comms. A hawk decided to use it as a vantage point to look
over the surrounding acreage. Never had a problem with other kinds of birds
roosting on the antenna. Must have been because the hawk was real and not
