Acopian BirdSavers - Prevent Birds From Flying Into Windows

"Hummingbirds were always flying into a big picture window at our mountain house. Since installing the BirdSavers we haven’t had any fly into the window."

"The BirdSavers are on every window of our passive solar house, all 17 of them. BirdSavers are truly just that -- they save birds! We had multiple fatal strikes every year until we installed these marvellous cords. Swallows, starlings, kingbirds, sparrows, finches, even a pheasant. We were heartbroken with every one and tried everything we could find: decals, CDs hung on fishing line, mylar streamers. Nothing worked. But BirdSavers do! We have had them for over 4 years now and have had no bird strikes! We couldn't be more pleased with the way they work, the way they look, the easy installation and everything about them. BirdSavers are miraculous -- they do what they promise and do it simply and easily. We encourage everyone to "stop the thuds" and install Acopian Birdsavers. The birds will thank you! I believe in every word I wrote and we will always be grateful to Acopian BirdSavers. Thanks, Jeff!"

"After three years of increasing problems with orioles, cardinals and robins hitting our windows, I came across the Acopian website. I followed the directions and made Zen Wind Curtains for seven of our windows.... easy to make and attach. What a difference they have made. Since they have been up, we have had no deaths of birds flying into the windows. The BirdSavers do not interrupt our views. Cleaning windows is easy, and does not require removal. We have had the curtains in place now for several years, and have shared the BirdSavers web site with other interested friends. They are a great solution... and such an easy solution, if only people knew about them. I am also impressed that while the site also sells the curtains pre-made, the instructions to "make your own" are shared for free, and are so easy to follow, so as to make them readily available. Acopian BirdSavers is a successful, inexpensive and attractive answer to help save our winged friends!"

"The BirdSavers are on the outside of large sunroom windows. A bird feeder is about 25 feet away. Before I put the BirdSavers up I was going to take the feeder down as too many birds hit the sunroom windows. The BirdSavers were installed three years ago or so and not one bird has hit my windows since then. None. They are amazing. I am totally satisfied with the results. They resulted in NO Bird strikes for over three years. They also look good on the Windows. We barely see them when we look out the windows in our sun room. I highly recommend this product to everyone who wants to prevent bird deaths from strikes."

A Simple Way to Save Birds!

When people think of bird mortality they usually think of cats, wind turbines, and pesticide poisoning, among other causes. In fact, in North America the largest number of birds are killed each year by glass!
