We are conducting surveys, monitoring, and research on cougars (puma, mountain lion) on the Ladder Ranch in south-central New Mexico. Here, cougars are of particular interest given their effects on state-endangered desert bighorn sheep and other valuable big game. These projects are also resources for training and education, most notably through the Cougar Field Workshop.

We have an interesting series of scent behavior being displayed by three different carnivores at the same location in the photos from top to bottom. On the 28th of January a coyote (Canis latrans) scent marked this spot. Only five days later a gray fox (Urocyon cinereoargenteus) stopped to scent mark the same spot. One week later, our collared male LM3 got his nose caught by these scents. Because our cameras have a 1 minute delay, we can't be sure that LM3 didn't also scent mark this spot, although there was no definite scrape made.
