I'm sticking with Fisher. It's easy to say it's this, this, or this, but you have to look at what is in front of you objectively. The photo shows no size reference, but it was stated the tracks are about 2 inches by two inches. That could be a whole range of animals! It's often damn hard to distinguish fox from coyote, if not at times impossible.
The tracks in the photo, just at quick glance, do not look like fox or
coyote because of the toes. Both the toe and the nail marks are too long. It's hard to tell if four or five toes are showing. Fishers and Martens often only show four, or the last is faint and hard to see. Also, the heel pad is quite small and all tracks shown are direct-registering. Fox and coyote tracks will show a larger, more distinct heel pad.
Gates of all animals can vary widely, but generally, fox and coyote tracks do not
all direct-register as shown above. Fisher and Marten often do. Given the size of the tracks, and that Fishers are larger than Martens, my vote remains Fisher.
