Last week, for the first time ever, I saw a red fox in my back yard. My camera was right beside me but had no memory card in it and I cursed myself for missing the opportunity. The next afternoon, right around the same time, I saw the fox again. This time the camera had a memory card and the right lens, but it was in another room. By the time I grabbed it and got back, this was all I was able to capture, as the white poof on the end of his tail disappeared over the fence.
Every chance I've had since then, I've made sure that my camera was nearby and fully ready to go but I haven't seen him since. :( and I'm still kicking myself.
I have the same luck with my red fox. Every time he shows up the camera is in the wrong room, the wrong lens is on or he gets startled when I try to get close to the window. I opened the shade one day and he trotted up and sat down on the sidewalk about five feet from the window. Of course, gone before I could get the camera.
