Summer monsoons can fill them with dangerous speed, otherwise they wait in quiet thirst. Lizards scatter or bask. Small bands of javelinas survive this parched climate, so squat and ugly they seem to be creatures from science fiction. They feed on the prickly pear cacti oblivious to the long sharp spines. A scream in the night indicates that a coyote has decreased the over abundant rabbit population by one.
Nature has no pity as it brings balance to the desert world.
The trees are filled with birds so diverse that I won't begin to try to name them. Hummingbirds dart around in search of succulent blossoms. Ravens and an occasional hawk soar across the sky. Quail lead a line of their fuzzy babies. Roadrunners dash about in search of lunch.
