Question from Tonie: We have a cardinal that keeps crashing into our front window then he flies to the back where he crashes into a glass sliding door! He must be knocking himself silly! What can I do for him? Why is he doing this?
The Cardinal sees his reflection and thinks it's an intruding male on his territory. For our birds here in Texas, breeding season in terms of staking out territories has already begun. The thing to do is to put up window decals of falcons, the natural predator of birds, or leaf decals that distract birds from windows. You can buy the decals online at any number of places (just type in "Window Decals for Birds" in a search engine like Google. Even Amazon.com has the decals. They're not expensive.
