Dipo, the Little Desert "Kangaroo" 543 Poised for Instant Flight, "Swifty" Accepts a Fly One of Dipo's most interesting neighbors is the zebra-tailed lizard (Callisaurus draconoides) which speeds over the desert sands so swiftly that it can catch insects in flight. When running, it curls its tail upward, revealing the bold black bars which give it its name. If badly frightened, it sometimes raises its forebody and races along on its hind legs for short distances. This reptile is entirely harmless. Leconte's Thrasher Fills the Desert Air with Ecstatic Song This bird can run almost as fast as a horse. One year a pair came to the ranch every day throughout the summer and autumn, favoring the author with their sweet song. On a memorable day in December, with five inches of snow, they appeared with feathers much puffed out. Though ordinarily shy, they came into the cabin through an open door, to escape that strange white blanket.
