Watching ravens over the course of decades has attuned me to the many ways they take advantage of the changes our kind has made in the desert. Prior to the establishment of our cities the place was an unremitting solar oven with scant shelter from the baking rays of the sun. It was a very hard place to be a large, black bird. But we build our buildings and plant our trees and, presto-change-o, suddenly the desert ain’t such a bad place to be. In the heat of the day, from April to October, you’ll see them hanging out in shade we make for them, lounging in comfort.
