The last entry provided information on birdhouses. This one deals with birds and houses (our houses), particularly the windows on our houses.
It's been tough to find ways of preventing these collisions, but today, I came across some interesting tips from the American Bird Conservancy. Check out the PDF of the info here. Along with the tips, the guide includes information on where to get the things you'll need to put the strategies to work. I haven't tried any of these yet, but the use of decorative Tempora paint definitely looks interesting.
