In the winter Moose feed mainly by browsing on twigs and by scraping bark off of trees. Like White-tailed Deer and other ruminants, Moose lack incisors in their upper jaw; they bite off their food between their lower incisors and a hard pad on the upper gum.
An obvious sign of Moose is the “incisor scrapes” they make when removing bark from trees with their lower incisors. An upwards movement of their head enables them to scrape a strip of bark from the tree. Sometimes instead of a clean scrape, neatly cut at both ends, you will see shredded bits of bark flapping at the top of a scrape. This occurs when a Moose begins a scrape and then grabs the piece of bark between its incisors and hard palate and pulls it upwards, peeling off a strip.
When in Moose habitat, look for the incisor scrapes of Moose on Red and Striped Maple, Willow, Trembling Aspen, Balsam Fir and Mountain Ash. Moose scrapings can be found starting as low as ten inches from the ground and can extend as high as eight feet (most likely made by a Moose standing on snow).
