One of the most wonderful scenes at a bee hive is the arrival of bees "packing pollen."
Bees will fly about 2 miles from the hive to find a pollen source. After getting their leg pouches full of pollen, bees will fly back to the hive and sometimes literally fall into the hive with their heavy baggage. Their pollen-filled legs are obvious as they slide into the hive entrance.
Once they lighten the load, they do a little waggle dance to communicate to other bees where they found pollen.
Pollen is the basic ingredient bees use to make honey.
