Watch the bees at work.

The bees take about 12 trips in and out of the hive on a good day and visit 50-100 flowers on each trip. If you watch carefully you can see the guard bees that stay near the entrance smelling each bee that comes in. if the guards smell a bee visiting from another hive to steal honey, a wasp, or other predator you can watch them battle right on the front porch.
