“In summer, when long daylight hours stimulate growth in the sparse vegetation,
musk oxen live well and grow fat. In winter, food plants lie deep under hard-packed
snow, which the oxen scrape away with their hooves. This is the hungry time, when
they survive mainly on the fat that they stored during the summer.
Others, too, are hungry, including bands of timber wolves, which sometimes follow
the musk oxen. In spring, when the calves are born, the wolves become particularly
menacing. The musk oxen form a defensive ring, with calves and young animals in
the middle. Even a dozen wolves attacking together stand little chance against that
circle of lowered heads and sturdy horns.”
