We have a couple lychee and longan trees in our yard that the blackbirds used to raid like a swarm of locusts. We tried cd's, pie plates, sling shots (never hit any), plastic owl, nothing worked. So this year I went online looking for something cheap that might help. I saw this thing and the reviews were good so I bought one. All it is , is a couple beachballs with eyes and a place to tie a string to. You get mylar strips in the package also. I took a 16' PVC pipe and put a 90 degree elbow on the end and a 24" piece sticking out and tied the thing to it. Then I took a few large cable ties and attached the pipe to the tree so the thing hangs a little above the tree top. The flimsiness of the PVC gives it a little extra sway. The blackbirds would not even land in the yard for the first week, and after that, the closest they ever got was a couple trees away, where they all just looked at it while complaining loudly. It really did work well on the blackbirds, however apparently bluejays have nads of steel, as they couldn't have cared less if it was there or not. Luckily there aren't that many of them here.
