This is a beehive that has many bees working in it. Most of the bees in it are regurgitating nectar until it is the right consistency for their honey. Other bees are outside trying to get nectar from flowers.
Inside the bee hive, the bees regurgitate some of the nectar into honeypots for the queen to have so she can help their hive reproduce,
Bees are also very picky about what flower they take nectar out of because the more sugar nectar has, the honey will be thicker, and it will take longer to barf up. The less sugar it is the thinner the liquid will be and the quicker it will take to barf up. The color, shape, and size of the flower is also very important to the bee.
