Most of the bees were active in the higher parts of the tree and it was necessary to climb up into the branches in order to secure about half the specimens.  The bees seemed to come in waves.  They would be numerous 4-5 for about five minutes, then it would be hard to find them & then after about ten minutes or so there were would many bees working again.
