Burton's Carpet Viper

So excited to spot a viper for the first time! :-) And more excited to get a decent video (which PN/YouTube is not saving the link for, for some reason: https://www.youtube.com/watch?v=rFiVTIuiqrM)

"Like other vipers, Echis coloratus is a venomous snake with a relatively short, stocky body, a wide head, vertical pupils and heavily keeled scales. It receives its common name (Saw-Scaled) from its defensive display, in which the scales are rubbed together by drawing opposing coils of the body against each other, producing a loud rasping or sawing sound.

This viper is usually grey, brown or brownish-red, with a lighter underside and with a pattern of large, light pinkish or greyish blotches or cross-bands along the back. The blotches may have a darker outline, and may contain shades of light grey or blue. The upper side of the viper’s head is usually brown, with a lighter ‘X’ shaped marking and a darker grey streak that runs from the corner of the mouth to the eye." ~ ARKive.org
