I was shocked to find out that the average life span of a red fox is 1 1/2 to 2 years. That's too short! It's a tough world out there, and their habitat is mainly suburban now, fraught with dangers such as humans that are afraid they are rabid and a threat to their pets or children, humans who feed them (A fed fox is a dead fox), and busy roads, to name just a few.
It's not easy being red.
I've included this last photo to show how much space I give them when I am photographing them. The fox is in my neighbor's yard, resting on a boulder. I am in my car on my driveway, engine off, taking pictures through the window. This one felt secure enough in its spot to rest while I was present. Awww.
