I finally got a shot of more than one! It is very grainy due to the high ISO under low light and the use of a zoom lens. It is so hard to get more than one and still have decent composition and interest (in my opinion). After observing them over the course of a few weeks, I have learned that there is a mom and four kits! I am careful not to bother them too much because I don't want them to become careless around humans (I know some of you agree). I expect they will soon leave the area or at least split up and venture farther away.
Thanks so much for the comments on my fox image yesterday! It was such a thrill to capture him laying there without a concern in the world.
