Thanks much for this posts. Though I have not commented before, I visit nearly every post. This one was of particular interest to be because we had a very large number of honey bees visiting our heated bird bath earlier this spring. The entire edge would often be lined with bees, usually between about 10am and 4pm. As well, they were particularly attracted to a flat, round, heater that was situated in the center. I had two hypotheses about this: 1. They were eating the algae that was growing on the heater, and 2. It gave them a good place to stand while drinking. Do you think they were eating algae? When temperature allowed, we removed the heater and the number of bees diminished significantly.  
Thanks again, rv

Thank you for your email. According to Eric Mussen: "I have not heard of honey bees actually eating plant tissues. However, honey bees require 23-methychlesterol in their diets and algae have a lot of it."
