Dressing up to do battle

One afternoon, at the end of March, I went looking for one of my favorite spring wildflowers, Marah oreganus, also known as Manroot and Wild cucumber. It sprawls along rocky places and I had recently discovered that it grows wantonly  in a partially quarried rocky area in Howarth Park. As usual, I had trouble figuring out how to draw this long, sprawling plant and was thinking about giving up when I heard a tiny ruckus on the next rock over. I looked up to see two Western fence lizards (Sceloporus occidentalis), in colors I'd never seen before, fighting and posturing with great vigor. I thought there might be a female involved and I soon found her, peering out of a crevasse on a ledge below the action. The males continued to interact with one another for quite a while. Then one of them left, only to return again, and they picked up where they'd left off. A bit later they both went to opposite ends of the slab and rested up for the next round. The female had climbed out of the crevasse and looked a bit exhausted, though she began to recover (from what?) before very long. As the males resumed their battle, a young lizard climbed up the to view the proceedings from the edge of the rock. One of the males chased him away and I watched as he headed my way, only to stop short when he noticed me noticing him. When I once again turned my attention to the territory struggle, the female had climbed up the cliff and was standing next to one of the males. The other male turned around and headed off slowly through the grasses at the edge of the battleground. I watched him until he disappeared and when I looked back at the victor and his mate, I was astonished to find that his brilliant colors and pattern had reverted to a pattern almost identical to her drab brown!
