This is the Top Bar Beehive that I built. You can get more information on these here:
I set it up about 30 feet from my existing hive (YouTube - User: Zardiw).
I was hoping when the original hive threw a swarm that they would move into the Top Bar. I used some lemon grass oil, and some honey comb I had to entice them.
One day I went out there to check, and a swarm had moved in!
Most likely the lemon grass oil/honey comb wasn't necessary, since the scouts from the swarm would no doubt have found it anyway.

This shows where the window is located.
Looking at the top bars from underneath:
4-21-2011. Approx. date of swarm moving in.
Taken 5-8-2011. They've done a lot of work in 2 weeks!
5-17-2011: More combs built. It's been a bit cool lately, so they're mostly staying inside.
