Chuckawallas are pretty cool lizards. The elevation where I live is too low for them, but perfect for desert iguanas. I've derived a lot of entertainment watching them do thier little territorial routines on a hot day. One will intrude on another iguana's space. Next, a "Pushup" contest ensues, followed inevitably by a mad dash as the interloper is chased off. The funniest part is that the "chasee" usually winds up in yet another iguana's "space", and the cycle starts all over again!Watching the local wildlife is one of the pleasures I moved to the rural desert for.
