About:

This blog is predominately about camera trapping in California. We camera trap to save our souls and to teach primary school students about biology and conservation. We will also touch on other camera trapping news and musings, sets from afar, mediocre herpetology, sucky birding, and other natural history discussions.

Sierra Valley Foxes Continued

About a month ago I posted about some gray foxes in the Sierra Valley.  We got pretty good shots of mom and pup.  Well, I had also set an IR camera up on video at the same set, that I only now downloaded.  I had forgotten it was set to video and thought it was on still image so I was not all that excited about looking at IR stills when I had the nice color homebrew pics.  See I have a ScoutGuard model that has the programmer and image viewer on a remote control.  I don't have a clue where my remote control is, hence how I did not know whether it was set to video or still.

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.

  2. Good stuff Jake. Looks like you caught a full family. Notice also that in that first vid your homebrew only takes 2 photos in 46 seconds - shows that if the animal isn't moving much, the sensors stop "seeing" them. IMO - that's a flaw in the design.

  3. Used a little bit of lure, but they were living in that rock pile so it may not have been necessary. I too noticed that it spaced out the pictures pretty far. I was pretty surprised that there were more than two foxes as nothing in the still images had led me to believe that would be true.

  4. Well, the fact that gray foxes look like clones to us didn't help.

    Btw - the missing pics is one reason why I like the Reconyx, even though it's low qual. Instead of the homebrew's "shoot photos as long as there is an IR signature," it allows you to set it to take 1, 2, 3 or 5 pics after a trigger, and then go to sleep until the next trigger. So, in the case of your fox, a Reconyx on "5 shots" would have gotten at least 10 photos of the foxes. Would be nice if the homebrews had such a setting. Of course, it can lead to lots of extra empty photos, but it would be nice to have the option.

  5. Can the Reconyx be triggered in the middle of the "shooting series" that you mention, or does the cycle have to complete itself?

  6. The Reconyx shooting series cycle always completes itself, so I'm not exactly sure if the camera will accept a new trigger during a cycle, and thus keep shooting cycles back-to-back. Some of the series I've gotten, such as the collared cougars, seem to suggest that it does. But even if it doesn't, I'm not sure it matters, because the Reconyx shoots a photo per second, and thus is ready again in ~5 seconds on the "5 shots" setting.
