So I was pleasantly surprised when I downloaded the files and realized they were videos.
But first a still shot from the next morning to set the scene a bit in your mind while you watch the videos.
These first couple of videos do a great job of showing just how little the gray foxes care about the homebrew white-flash. The homebrew gives a couple of early flashes (red-eye reduction mode) and then gives the big flash and takes the image.
I thought we had a mom and her pup. But in this video (88) it appears there are three maybe four individuals. You never see more than two at a time, but unless exits the scene at the bottom one circles back around and re-enters the scene from the top in a matter of seconds mom may have had more than one pup.
In this video one fox finds the camera and moves it around a bit.
