A peaceful Sunday afternoon - the perfect time to sit on the front porch. From my rocking chair, I can see the hummingbirds as they refuel at our hummingbird feeder. An agile bird, at times almost twitchy, I watch as one approachs the feeder. The hummer gives it a brief look, followed by a dart forward, a quick drink, and a backwards retreat. This cycle may be repeated several times until suddenly, in a blink of the eye, the hummer’s gone. Gone until the next visit, that is.
