MARVELOUS!!! My Birds, & I, Love them!
I love my birds & critters - & provide seeds & water (with heater in the winter) & all year round.
I've even completed the National Wildlife Federation's Certification Checklist & received their "Certified Wildlife Habitat' Certificate.
For some reason, this year the birds were flying into my windows several times a day. I'd stop whatever I was doing to check to see if the bird was okay (fortunately I never found any birds lying on the ground, but knew they don't always die immediately). This was extremely distressing, I certainly did not want to harm my birds - all I could think was that the Clings I had on my windows were no longer working.
So, I ordered these clings, & some from 2 other manufacturers (just in case these didn't work.).
As soon as they arrived I put them on my nice clean windows.
Since then, NOT ONE Bird Strike!!
My birds, & I, THANK YOU!!
I would recommend these to anyone who wants to keep their wild bird life safe from life threatening hazards.
