LF1 was at one location in Big Rocky Canyon from 24 July through 30 July. This is one of the longer stays in one spot we have seen. This may be a large prey item or multiple prey items. Of course, we continue to hope that we can record a litter of cubs. We have not received the last two downloads for LM1.

You can clearly see a gray fox in the photo above. If you look closely you will see a skunk only a few feet behind. This is not the first time we've seen a skunk and a fox in the same photo. It is worth wondering if this is not a non-random association. And there is precedent for two species foraging together. For example, it is known that coyotes and badgers will form hunting associations.
Above we have a photo of a bobcat traveling along an arrollo. With photographs of sufficient quality, bobcats may be individually identified by their spots. Using individual identification and regular photo sampling it is possible to estimate the bobcat population size. This technique has been used with success with tigers which can be individually identified by their unique striping patterns.
Recent heavy rains down on the Ladder has destroyed 5 of our remote cameras. Unfortunately, this is a significant set back for our detection probability study. Eleven cameras still remain in our sampling grid. Above are a few of our more interesting recent photos. Immediately above we have a rare photo of a badger. Out of more than 1,000 camera nights on the Armendaris Ranch in 2006-2007 we recorded only 3 badger photos. This likely has more to do with the placement of cameras and badger habitat preferences than it does with badger abundance.

A fresh kill was found by Mike Mader on June 26th when he noticed a drag mark across the main road down Animas. I placed a camera on the site to get photos of the lion responsible. An uncollared female lion dragged this Elk calf over 200 yards before caching it under a stand of oak trees lining the road. She made the kill in the early morning of the 26th, then visited it again on the same evening when she moved the carcass to a nearby 2nd cache site. She revisited the carcass on the 27th in the early evening. On the 28th the carcass had been moved again,left uncovered, and was mostly eaten. The lion did not appear to revisit the kill after leaving it on the 27th.
