Crashes occur two or three times per year, but even that is too frequent for me.

We built our house with the backyard on the south side, with large windows: it is wonderful to look out at all times of year and see our big garden. But I am sad to loose the occasional chickadee or hummingbird.

All suggestions welcome. Thank you!

One thing I've had some luck with is to cut out the silhouette of a hawk and tape it to your window (you can probably buy this from some of the mail-order pest control companies). The hawk shape instinctively causes fear and a reverse in course by most birds. The down-side is that if your feeder is next to this window, you'll probably drive away a lot of your desired birds.

Perhaps you can put a window treatment on the glass, to reduce its reflectivity? That shouldn't repel the birds...just prevent them from thinking their territory is being invaded.

Hope this helps.
