Out by our garage. We've had some killer cold for two weeks. (St Louis area)

I wonder if that is contributing factor? I've lived her almost 12 years, and this is the very first time I've even seen a Bluebird in my area. It might be due to the fact that I have many wrens that nest around here. I almost bought or built a bluebird box(s) when I first moved here. I didn't since I read that wrens will kill their young. I didn't want any part of that.

It doesn't look injured in any way. Such a shame! It is so beautiful! I just love bluebirds!
