More head-banging news from the land of hard knocks.Our bodies do a lot of weird things, and many of them are completely involuntary.

Joyas Voladoras
Something to think about before our April 4 show
on Andean hummingbirds
Anna’s Hummingbird female (Jim Kenney 8/14/12)
Joyas Voladoras
by Brian Doyle
From: The American Scholar
Consider the hummingbird for a long moment. A hummingbird’s heart beats ten times a second. A hummingbird’s heart is the size of a pencil eraser. A hummingbird’s heart is a lot of the hummingbird. Joyas voladoras, flying jewels, the first white explorers in the Americas called them, and the white men had never seen such creatures, for hummingbirds came into the world only in the Americas, nowhere else in the universe, more than three hundred species of them whirring and zooming and nectaring in hummer time zones nine times removed from ours, their hearts hammering faster than we could clearly hear if we pressed our elephantine ears to their infinitesimal chests.

If you were to film this goop and play the video back in high speed, you’d see something that might remind you of the 1950s sci-fi classic “The Blob:” a jelly-like creature pulsating in a strange way, a little bit forward, a little bit back, spreading and searching for something to devour.
