Birds attacking reflective shadecloth!

[Selmo]

Has anyone else had this problem? The birds, starlings, have been stealing the reflective tinsel, for their nests. In the neighbors tin shed behind our back yard. And have tore three foot by one foot hole in the shade cloth. There was a twenty foot cherry tree about ten to fifteen away from the damage. So, we cut off all the limbs on that side of the tree. Now the tree is 25 to 30 feet away now. We hung some strips of cotton cloth from some of the remaining branches to move in the wind. Which would hopefully scare the birds away. Did not work. Hole got bigger. Last week we bought a owl decoy. Put the owl in the tree and so far the hole has stayed the same. Don't know if it is the owl or the starlings are done nesting now. Hopefully it is the owl. Has anyone else had this kind of problem and what worked best for you (gun?).Hope no body has really had to deal with this, but thanks in advance
