The swarm season for bees is underway. A spring phenomenon, this is an event that is growing rarer to see as the global bee population is rapidly declining due to various threats to their life cycles. Swarm season is actually an important step in bee colonies’ natural reproduction. Bees swarm a temporary home such as a tree branch while scouts go out to find new homes (aka hives) for the season. In this process, one swarm often becomes two or more colonies. If you see a cluster of bees, do not panic! Simply contact a local beekeeper if you need them removed or simply leave them be as they are often gone within two weeks. 
If you desire to have the bee swarm removed, call a beekeeper, your County Extension Office, local beekeeping club, police department, or a similar organization. Many of them will gladly direct you to a beekeeper who would be happy to pick up these bees and give them a good home. Swarms are usually quite docile as they have no need to defend their hive, so simply walk away and contact an expert to keep everyone – and everybee – involved safe and sound!
