Upside Down, Inside Out

Hummingbird hardly heard, airily, merrily extraordinarily effortless floating, near weightless transparency, seemingly without the slightest of care. Urgent persistency, terribly panicky, frenzied and frantic, she's burning through energy rapidly, hungrily; precise machinery executes there. Mallard so lazily, buoyantly floating on glassy flat waters, he glides on the surface, and wanders unhurriedly, conveying contentment, trivial feat. Feet like a bicycle furious pedaling, splendidly, swimmingly, chasing and fishing, he's hungrily hunting and ready to eat.
