How to prevent birds from flying into windows

One possible explanation for why birds fly into windows is that they see a reflection of the outdoors, thinking they can fly right through. (When looking at the window reflections in these pictures, it's pretty obvious to see how this could happen.)

Another explanation is that, during mating season, birds see their reflection as a competitor that has to be fought off.

And if you're considering putting up bird feeders, waterers or bird houses, you're increasing the chances of bird-window collisions.

At our house, we'd had several casualties from birds flying into our window, so something had to be done. The challenges were that we have very limited carpentry skills, couldn't invest a lot of money, and didn't want to obstruct our view from inside the home.

Since most of our windows don't open, they can't accommodate screens. So, here's a photo of what we decided on:

netting to prevent birds from hitting windows

At Lowes, we purchased:

• 1 roll of 7'x100' wildlife netting ($13)
• 2 10-packs of 6' long by 1 1/2" wide lath strips ($9/pack)
• a pack of 9/16" wood staples ($3)
• 6 1" spring clamps ($11)
• a tube of liquid nails (optional)

Since this row of windows measures 16' wide by 6' high, we cut an 18' strip of the 7' wide netting and spread it out on the deck. To add just a little weight to the bottom of the netting (but not so much that it might compromise the gutters) -- and to add stability to the top of the netting, we aligned 3 pairs of lathing along both the top and bottom of the netting, with the netting sandwiched between. The lath strips were then stapled together with dabs of Liquid Nails to keep the slats together.

Lastly, we clamped the top of the netting onto our gutters with the spring clamps.

So far, we've had no more bird collisions. And the netting is virtually invisible from inside our house.

I have a problem with a kookaburra flying into my many glass sliding doors. Your solution looks like a good solution, but I believe the birds will still see their reflection and fly into the glass, and then get caught up in the netting.

Thanks for your comment. I don't know how kookaburras would respond but the large wall of windows you see in the photos above is directly in front of me as I work on the computer all day. So, I'd certainly notice if birds got hung up, even temporarily. Thankfully, I haven't seen birds come in contact with the netting even once, though they often sit on the deck railing just a few feet away.
For as 1) inexpensive as it is, 2) easy as it was to install, 3) effective as it has been and 4) well as it has held up (even though it is practically invisible from inside the house, the netting still looks like new... even after a couple years in the sun), it's been a wonderful solution for us.

Do the birds see the netting? Or do they hit it instead? Just want to be sure I don't buy a netting that has the wrong spacing that they might get caught in. Some of the birds hitting my windows are hummingbirds. Thanks again for the great idea!

Hi Elizabeth,
Thanks for your message. We have an occasional hummingbird hovering around our deck... but I don't see nearly as many hummingbirds as songbirds.
In well over a year now, I've never once noticed a bird hit the netting... so they must see it... which is a tremendous relief. In the few months prior to hanging the garden netting, we had 4 or 5 goldfinch, bluebird and black-capped chickadee window strikes.

This is a terrific, affordable, good looking solution. So excited to find it - thanks for sharing!

Thank you very much for your positive feedback, gs.
We couldn't be any happier with how this has worked out; not a single bird has hit the windows in 2 years now and the netting looks as good as the day we hung it.

If you're concerned about overall cost and keeping weight to a minimum so that your gutters don't sag, have you thought of using plastic zip ties instead of metal spring clamps to attach the netting slats to the gutters?

That's a wonderful idea Lewis. The zip ties are so much cheaper, lighter and, i suppose, can be quickly cut off if the netting should have to come down because of high winds.
