Beautiful patterns in nature ~ cryptic coloring

Summer is dawning on us gently this year in the Sonoran Desert. Two nights ago the Lesser Nighthawks began trilling - one of the signature sounds of desert summer. It is still cool - we haven't had any hot days yet. But the ancient rhythms carry on. Soon there will be nighthawk nests, which aren't really nests at all but just barely discernible indentations under a small shrub. A cryptically colored egg or two is laid. In a few weeks, a chick will hatch, if the parents are lucky, and it will be ready to fly very soon - nighthawk young are precocial, like baby quail - they must be ready to run or fly from predators very soon, since their rocky nests offer no protection. The egg above is beautiful - inspiration for a future art project.
