Why do bees build open air colonies?

In truth, I do not know exactly why a swarm of bees would chose to build their hive in the open air, and I'm positive there are many reasons. However, I'd love to hear why you think they chose to do so. Please leave your theories in the comment section and I will be sure to reply. Thanks for watching. God's peace to all.
