It may be possible to tell the difference between white-footed and deer mouse tracks, but I certainly can’t. The only clue that sometimes works is to note the habitat in which you see the tracks– they are somewhat more likely to be those of a deer mouse if they are in a coniferous forest, but not always! White-footed and deer mice often travel on top of the snow. They are bounders, leaving tracks that resemble those of a miniature rabbit, with the larger back feet landing in front of the smaller front feet. There is often a tail mark, but not always, as they can and do hold their tails vertically at times.
