Waste not want not

I have noticed after we have had a windy day lots of buds blown off the Spotted Gum,  Eucalyptus maculata Subgenus Corymbia that is in our driveway circle. What brought my attention to all the buds was the hum of dozens of honey bees that were collecting pollen and nectar from the freshly opened buds scattered over the driveway. I was quite taken by the fact that there were no other sources of food for the bees in the vicinity at ground level and the flowers on the tree are some 40 feet above ground, that the bees' senses are powerful enough to pick up on these fallen buds.
