Fishers Climbing Trees

12-19-16-fisher-tracks-up-tree-049a2363If you look at the tree in the center of the photograph, you may be able to detect paired tracks in the snow along the length of its trunk.  As luck would have it, a fisher chose to ascend the one tree with snow still clinging to its trunk. Fishers are members of the weasel family and are well known for their ability to climb trees.  They do so in order to reach den sites as well as to catch prey. Fishers’ arboreal adaptations include semi-retractable claws and ankle joints that rotate so that they can descend trees head-first. Smaller females appear to be more adept in the trees than the larger males.
