Tracks. Old photo from 1999. I was digging out my old digital photos and found a bunch of animal track and sign images. Date is accurate.
Characteristic woodrat urine stains; yellow -brown stains suggest recent occupation. Talus habitat and elevation (about 6580 feet) suggest N cinerea over other woodrat species.
There were numerous probe holes in the dunes, I believe they were made by a flicker. Narrow bird tracks are visible just below the probe mark.
Typical corvid tracks with bulbous toes and toe# 2 and toe #3 hugging each other. Too small for crow. The documented trail shows the animal was walking, an unusual behavior for jays. Magpies are also common in this area. I have never seen magpie tracks and there are few documented occurrences, so I'd be happy to discuss other theories.
Scats also found within 15 feet of trail camera that captured lion activity.
Note Deer hooves visible in chunks at lowest right and between inches 5 and 6 on ruler.
scat confirmed by trail camera of the deposit
The feather with attached bones was about 3-4 inches in length.
