Two New Hampshire men were enjoying a brisk day indoors when an adult female moose -- which are called "cows" and weigh an average of 1,000 pounds -- lumbered up to their window, looking for a snack. Unsure what to offer their new friend, one man gave the cow a piece of bread, which she seemed to accept gladly -- but then she didn't leave. That's because moose can become quickly habituated to humans' presence, especially when those humans have food to share. The animals are fairly indiscriminate and impressive eaters, according to the New Hampshire Fish & Game Department: the average adult moose eats anywhere from 40 to 60 pounds of twigs, leaves, buds, and shrubs daily. And although they often appear calm or friendly around people, moose can become agitated without warning -- or without food when they expect it. That might explain why, after the men offered the cow ginger snaps, it still took some kind words and encouragement to get her back into the woods.
