There is tons of stuff going on with the bees. There are more and more visible every day - perched on the hive entrance, coming and going, looking out from inside, zooming across the yard, on the flowers near the house...
Here's a photo of the hive. There are two bees sitting next to each other and their wings are beating so quickly that you can't see them. The purpose is to disperse the scent of the hive to guide the other workers back, but also, in the warm weather, bees will line up on their porch and do this to help circulate air through the hive body.
