I was outside in the back yard, putting a couple of the Bali tomato seedlings into the Earthbox and heard a buzzing sound – which I assumed to be a small plane approaching the nearby airport, which they do frequently. I was wrong. The buzz was approaching loudly and fast and it passed overhead quite quickly – with a noticeable Doppler shift which allowed me to look up and immediately locate a pretty good sized swarm of bees heading west. I don’t know if that means the hive in the front yard has split, or this was another group of bees, but it looked to me like they might be heading to another large tree down the block! Kind of cool.
