Trailed gray fox all morning but forgot to take photos until fresh snow had filled in most of the tracks. They were traveling and foraging along the railway corridor and passing by potential den sites.
Overnight snow dates these tracks to early this morning; it snowed until 5AM and then started again around 10AM.
Seen crossing the street, heading NW as I drove past.
Tracks cross Austin Dr North to South and continue through the forested patch towards Red Rocks Park. Red Fox tracks also seen at the Red Rocks Park boundary this same day.
Last snowfall overnight 1/4. Tracks laid since then.
I back-trailed this gray fox starting near Red Rocks Park, through the forested stretch behind the CCTA garage and the backyards of Austin Dr, all the way across Austin Dr where it curves. The fox was traveling North to South.
Last snowfall overnight Monday 1/4. This fox passed through Tuesday or Wednesday.
Fisher tracks, loping in a WSW direction. I followed them to a large White Pine towards the western lake edge of Red Rocks Park.
Length approx. 4"
Fresh tracks, from the previous night or early morning. Snow stopped falling around 11 PM on 1/4/16.
River otter tracks ascending east bank of Potash Brook from silty to sandy substrate. Two parallel sets of tracks, headed downstream. Tracks could be several days old.
Front track: 2.75-2.8" w, 2.6-2.7" l
Hind track: 2.85-2.9" w (couldn't distinguish length)
Trail width: 7.0-7.8"
Webbing apparent between toes of some tracks.
Fisher ruled out by relative size and position of toe 1 on hind track.
