Is there something besides the plexiglass to use so you can see the birds but they can't see you?

There is a company window film and more that sells (windowfilmandmore.com) that sell sheets of one way mirrors (the stuff that I guess is in the window feeder that costs a whole lot more), and other glass covers that may work. They sent me free small samples (three total) but I haven't used anything yet because it hasn't gotten warm yet :) ... but any of the three look like they will work. I'm planning on using it for the window bird feeder also. (which ever one I end up picking)

You can buy the one way film to put on your window. Another thing we did with ours is to reinforce the hanging system so if the suction cups ever fail, the house won't fall and there will be no harm to the baby birds. All it takes is a little wire and a couple of small eye screws.

I would LOVE to know the answer to this question, too. It was marketed as such - supposed to include some sort of one-way mirrored film. But it didn't. I figure it's money wasted.

This was a gift, so I'm not sure. I seem to remember buying the one-way mirror film separately

Unfortunately, I have not been able to scare even small birds with this device. I have located it in several locations to no avail. I have gone to a blow up snake stuffed into the area where these birds are attempting to next. I still have the Owl hanging in the poximity however.

They need to be applied to the exterior of the window so the proper side that the birds see is out. The window needs to be cleaned before applying.

The mesh is 1/4 inch. It would certainly keep any bird out, but if you are using the balcony a larger mesh, such as 3/4 inch, may be preferable.

In my case in the PNW near Seattle the unit did not work well. The sticky paper was the only thing that did work. I certainly would not worry about catching birds though.

We didn't, but you do have that option. The hole is smoothed out so it will not hurt the bird when they get in the hole. We have a lot of little sparrows, wrens, chickdees and oriole so we wanted to make sure no blackbirds and larger birds were able to get in there.

Maybe a foot across diagonally. Range? It will fly beyond your ability to see it. That's when things get dicey!

Plexi glass is cheap and clear. You can zip strip pieces to the pannels. Also you can cut srips of newspaper and hang them by the center fold behind the litter pan.

It would seem possible, since this is a one-way viewing product. It might be a good idea to order a piece and try it in daylight and at night when the lights are on inside and dark outside (not necessarily when it needs to perform for the bird viewing.) Mary

I doubt the birds will attack themselves on your screened windows. The decals did not deter the birds on my uncovered windows though at all. I did not find the product effective at all.

I've found that I need at least 5 on a large window...spaced randomly, maybe 2 feet apart. Even then, we occasionally get a bird that doesn't see them! So, I guess a good rule of thumb would be the more the better!

I couldn't get it to work in broad sunlight. Five minutes after I installed it, there were birds landing right next to it. Even with the wind blowing it around.

There is glass on the backside and you can see in very clearly. Sadly, we've had ours on the window in two different locations for about a month and a half and have had no tenants. Think the birdies feel they would be too close to the humans. There is a nest under our patio about 6 feet away and many in the birdhouses in the trees.

Yes, the back is open for viewing. There is not, however, a mirrored film to go across it (so you can see the birds, but they can't see you).

If you stretch it out like a fence, I don't think so, even though it is hard to see with human eyes sometimes. You could even add some silver reflective tape which will help the deer know it's there too. However I also used it bunched up on the ground over small plants and I witnessed our cat trap a bird under the netting. It got tangled up primarily because it was startled. and did easily find its way out once I removed the cat. So in general likely bird-safe. Safer than windows for sure.

No, there's clear back to the bird house to see the nesting. The birds can see into your house . I'm not sure it works let. I just installed it.

I am probably answering this twice; it baled on me near the end. The UV liquid should work on mirrored glass. Birds should be able to see it. After application check with a UV light; if it is UV reflective, the birds can see it. I have lots of windows and lots of birds and this liquid works well!
