Hey all...

I used to work on the GNSI Journal and newsletters and a year ago my husband and I opened a Wild Birds Unlimited store here in Eugene. It has been a very fun and intense learning experience, of course, but interacting with the people who come in has been really great.

It is true that the UV Window Alerts DO work. Here's why: birds can see into the ultraviolet range and these have a UV coating on them that makes them glow when birds see them. The company that makes them is here in Oregon, in Bend and they're great to deal with. In our store, we sell lots of them and I now buy them by the dozen since they do work well and so many people have issues like this.

My husband, Dan, is an ornithologist, as well, so the store's mission of course is right up our alley, and he's been able to make a difference locally in our increased visibility here to help do lots of bird education. 

Some other recent research impacts one's decision on how to protect birds from window strikes, too, and that is research (I think done in PA) that showed that birds will try to fly between parachute cord (that 1/4" diam. greenish nylon cord) when it's hung in front of windows to deflect birds from striking them, as long as it's not wider apart than 4 1/25" apart. So, what that means, is that you should place things you want birds to regard so as to change their minds about flying through a space no less than 4" apart ideally. When the researchers placed the parachute cords 3.5" apart they were 100% able to deflect birds; at 4.25" they were only 80% effective at keeping birds from striking the windows beyond. 

So, if you choose to use the stickers, make sure to pace them fairly close together!
