The Basics of Iridescence

‘the bare bones of that fleeting / soap-bubble sheen’

“The brilliant iridescent colors of hummingbirds are … structural colors, not pigment, which means they are reflected by microscopic structural features of the feather surface … composed of layers of tiny air bubbles.”

—Ornithologist David Sibley, “The Basics of Iridescence in Hummingbirds

The basics of iridescence: the bare bones of that fleeting soap-bubble sheen, a pocket of breath caught in stained-glass evanescence— it will all make complete sense.

The basics of iridescence: the brass tacks of those glancing neon-green glimpses and ruby-throated flashpoints, bearing their beauty in fluorescence— it will all make complete sense.

The way the light changes, the light changes everything— as its waves endlessly advance over some midnight-feathered shore, crashing it into mercurial color and a complete and utter nonsense of wing-flashed brilliance.
