I didn't know if these are reg. bees, I thought they have a hive in a tree. I did not want to kill them if their are honey bees , as I know their numbers have been decreasing. THANKS

Without a much better description or photo, there is no way to ID bees. Sounds like a feral hive or a native bee. Best Identification can be made at your local Extension office.
I WILL TAKE ANOTHER PITCHER AND STOP BY THE LOCAL EXTENSION OFFICE. THANKS
