Birds can collide with windows in any season, but I've always noticed an increasing number of those sickening thuds in spring. As waves of migrating birds head north, we see both a huge increase in the number of individuals, and an increase in birds who are new to the neighborhood and more likely to be hoodwinked by windows.

Now that warm days are turning even window washing and yardwork into attractive tasks because they give us excuses to get outside, it's a good time to think about making your windows better for birds.
