The moose or elk (Alces alces) is the master of surviving the harsh winters of North America and Europe. They trek through snow almost a metre (six feet) deep for hours on end and clamber up rocky mountainsides with grace.
Moose attract the opposite sex by scent marking trees and bellowing, and while some males have harems of females, some moose simply pair up when it’s time to mate. In autumn when breeding season comes the large antlers of the males come into play, and only victors of battle get their pick of the ladies.
Young moose are born after 230 days and gain a kilogram (2.2 pounds) every day by drinking fat-rich milk. By the age of four or five moose are fully grown and begin to breed themselves.
