As the bees fill tubes, they add about 10 cocoons
for each tube filled.
Not sure how yet, but I intend to empty all the tubes at
the end of the nesting cycle.  I intend to keep track of
a number of factors for each tube
1. length of tube
2. diameter of tube
3. number of cocoons in tube
4. position of tube (left side, center or right side) in the house
5. condo address  #1 or #2
6. type of tube (paper-liner, cardboard(no liner), bamboo, routed wood

The data should be very instructive .

Next year I intend to mount the houses on the south side of house
so that they can get direct sun from both south and east sun.
