What is it about the hummingbird, a beautiful little flying machine, that is so enchanting and fascinating? Those of us lucky enough to experience them up close can name a few things, and at the top of the list most likely would be their ability to hover in place with their little wings beating up to 70 times a second. Their speed is also remarkable as they demonstrate when chasing each other around, and the list goes on . . . We’re thankful each year when they decide to grace us with their presence in the flower garden.
