This evening, the tiny couple had syphoned off the final droplets of nectar from the feeder. After a few dry runs they flitted away disappointed; their needle-like beaks found the portals to yield nothing. Finally, one of them flew up to the living room window, hovered there, and stared in at us as if to say, "Hey, Bill, we're out of food!"
I responded to their guilting.
Refilled, the reservoir of the feeder captured the final rays of the setting sun and transformed it into a sparkling red ball. Our little friends were happy!
