Hello Flowerpetal, I know the feeling about finding the deceased bluebird. If you read my original post at the beginning of this thread, you know I also lost bluebirds. The birds I lost also looked perfectly fine. I have had the same pair raising just off my back porch for the last 4 years. I had pennies in the birdbath for the first time last year. There didn't seem to be any problems with them then.
I am strongly suspecting some kind chemical poisoning, but wanted to be absolutely positive that the copper in the water was not to blame. I live in a neighborhood with many neighbors who use assorted chemicals to keep their lawns cosmetically "pleasing".
I have always heard that when something is poisoned it will make them very thirsty. The behaviors I saw, all three birds just sat at the birdbath for hours. I assumed they felt thirsty.
Thank you for sharing your experience!
