Out for a walk in the pre-dawn today, I was ascending the slope on one street when I saw above me, about 25 yards ahead, the silhouette of a red fox loping across the pavement into brush. As I reached the point where the fox had been, to trail it I turned down the crossing street where it had gone. I could hear it to my left moving through the trees and bushes about 5 to 10 yards away. The fox must have been alert to me because through these several minutes it kept up a series of screaming barks to warn me off. Then, still under cover, it coursed away into deeper brush, and I kept on my way along the sidewalk, the silence now as eerie in its way as the barking.
