I need a solution to my pigeon problem! My cars are in a direct line between two trees, and since pigeons aren't exactly discriminating in their choice of dropping sites they are often the target. I put this bird scare together with parts from my project bin in a half an hour! Free and fast, my two favorite 'F' words. :)
Because they have really nice tools and a big space, I made it at TechShop! http://www.TechShop.ws
Step 1: Gather Materials
For the bird scare you need:
4 Old CD's
1 3/4 PVC Cross
3 18 Inch pieces of 3/4 PVC Pipe
2 Fishing line Swivels
Epoxy or plastic glue
2 small eye screws
Flag Pole Mount
Drill and bits
Step 2: Assemble the Tree
Put the PVC pipe together as shown. The joints fit very tightly, so I didn't need glue.
Step 3: Paint!
PVC will degrade if exposed to direct sunlight. So I cleaned the PVC thoroughly and painted with a tan color I had in the workshop.
Step 4: Final Assembly
Drill a small hole in the top and bottom of the CD. The location should correspond to the size of your swivel.
Drill a small pilot hole and screw in the eye hooks in the ends of the of the PVC arms. I placed them about 2 inches in from the end.
Insert the swivel in the screw eyes and the CD's.
Step 5: Install Flagpole Mount
I already had a flagpole mount on the house, so I was able to skip this step.
Step 6: Profit!
Insert your Bird Scare into the Flag pole mount, tighten thumb screw.
Your Bird Scare is mounted and working! Now I am off to wash the car!
Reflective type Bird Scares should be mounted in a spot where they will get sunlight most of the day.
A cross fitting was used to allow for more scares. You can add more trees and different types of reflectors or chimes to further deter the birds.
