I now have two bee honeycombs outside my office window here in the Tân Bình district of Ho Chi Minh City.
The upper comb has been there for over a year.
A couple of weeks ago, some bees split off and started building the lower honeycomb. The bees never swarm, and my windows are always closed to keep the air conditioning in, so they do not bother anybody, and we leave them alone. I am impressed with their choice of location in the bougainvillea vine -- the honeycombs are sheltered from heavy rain by the tree branches and the building overhangs, and they do not get direct hot sun because of the shading of the leaves and flowers. My view from the window has long been obstructed by the growth of the vine, so I don't mind the new bulk of the honeycombs.
