This Hummingbird greeted me on the sidewalk on my way home:
The mysteries of the Hummingbird –
Never flapping their wings, but rotating them in a figure 8,
they reach near-infinities in flight –
Wingbeats of 70 times per second when casually flitting about.
Wingbeats of 200 times per second when in a high-speed dive.
Drinking of the nectar of life.
Heartbeats beating for joy 21 times per second.
