A heat-haze shudders. The border between land and air hums and crackles. Salvadora, their snake-scales plaited from the age-old landscape, lies still. Still like a languid echo of the simmering skyline. Still oh so still until – flit, flare, flash! A bright fury of colors catch light in a hot-sand-skimming horizontal dash! Undulating patterns — zipped-up-tight — twist, stretch, intersect in the frantic flight. Its vivid stripes emblazoned across the desert floor, Salvadora lies still again, poised to perform their mirage-miracle once more.
