What a cute idea. I wish birds didn't always crash into windows like they do.
On an unrelated note... I love your blog...how did you get your header to substitute for theirs? I don't really understand html, but you probably have to edit it that way, right? I got my image to insert but not at the top of the page like I want. (dieverdog.blogspot.com) Thanks, I love how you've done your blog.
This is a wonderful illo and a great idea! I would love it if someone would come up with a crash test bird. It broke my heart yesterday when a female cardinal crashed into our dining room window and died. All I could think of was, did she leave any babies. Maybe you should suggest this concept to the crash test industry.
