Bees at the Pier

We went out to the Pier the other evening to watch the sunset.  It was one of those evenings where there isn’t much to the sunset, really.  What was fascinating were the bees!

(I’ll be back tomorrow. I have photos but it is sleepy time.) 

Ok, I’m back (4/26/10)  Here are the Bees in a nest on the Pier over the Caloosahatchee River:

I have Questions:

1.  Why are the bees nesting here?  They are on recycled plastic, fake wood on the back of a bench.  Why do they perceive this to be a safe place to, um, be?

2.  Where were they nesting, before they picked this location?

3.  Are they building a honeycomb under all of themselves?  So, their honeycomb will stick to plastic?
