I normally only see wasps and bumblebees so it is kind of cool to see a "real" bee, but... a bummer that it is so hot for them.
I looked at the photo of Charleen's and also read the post about her adding rocks so the bees would not drown. One of the bees in my bird bath looked like it was doing the side stroke and I put a twig in to get him out. He fluttered his wings and flew away.
Thanks for the link, it was informative.
