The long-tailed weasel is the most widespread Mustelid of the Americas, it ranges from north of South America to the south of Canada. Once thought to be nocturnal, it also hunts by day, primarily on voles. They are known for their zig-zag pattern hunting from burrow to burrow. The reason why weasels in a chicken yard, may kill all the chickens (more than it needs), is because its instinct dictates it should procure food when available and store it afterwards. When weasels drag their rump on the ground, they are thought to leave a scent to let other weasels know its sex and maybe even its identity. The Long-tailed Weasel is hunted by hawks, owls, cats, foxes, and snakes.
