Robbing Activity

Q: Why are there so many bees going in and out of my hive so fast and furiously?
A: Looters in action! When there is a Nectar Flow in the area of the hive, there should be a higher rate of traffic than other times.
However, if the hive is not currently in a flow and there is a very high level of activity at the hive entrance(s), looting may be in progress. This is also known as robbing activity. (video below)
