However, they are still plenty active at night when it's cooler. In addition to the deer going by our house most nights, we discovered this summer that a gray fox travels by our house just about every night.
Red fox are fairly visible, often seen in the early morning or late afternoon, but I have never seen a gray fox during the day, as they are much more reclusive. But using an automatic camera I've found that the gray fox has a pretty well-planned routine. Here is what I recorded passing by our house last week:
Aug 8: 9:39 pm
Aug 10: 10:23 pm
Aug 11 4:10 am (really Aug 12)
Aug 12 9:52 pm
Aug 12 11:02 pm (in the opposite direction)
Aug 13: 9:52 pm
I also found the red fox on August 7, 8, & 9, though it tends to travel later in the night, most often between 2 to 4 am.
