Arctic foxes form monogamous pairs during the breeding season and they stay together to raise their young in complex underground dens. Occasionally, other family members may assist in raising their young. Natural predators of the Arctic fox are golden eagles, [12] Arctic wolves, polar bears, [13] wolverines, red foxes, and grizzly bears. [14] [15]
Wolves in Finland are protected only in the southern third of the country, and can be hunted in other areas during specific seasons, [8] though poaching remains common, with 90% of young wolf deaths being due to human predation, and the number of wolves killed exceeds the number of hunting licenses, in some areas by a factor of two. Furthermore ...

As many as 4,000 wolves may be harvested in Canada each year. [133] The wolf is a protected species in national parks under the Canada National Parks Act. [134]
Approximately 1,800 of the world's 10,000 bird species migrate long distances each year in response to the seasons. [17] Many of these migrations are north-south, with species feeding and breeding in high northern latitudes in the summer and moving some hundreds of kilometres south for the winter. [18]

The energy expenditure of chasing and fighting during the breeding season can result in a buck losing an immense amount of weight, with some research documenting losses of as much as 20% of body weight with some sources showing body mass losses of up to 30%. [11] On average, a buck before breeding season can weigh up to 180 pounds (82 kg).
A wolf's legs are long compared to their body size allowing them to travel up to 76 km (47 mi) in 12 hours. This adaptation allows wolves to locate prey within hours, but it can take days to find prey that can be killed without great risk. Moose and deer live singly in the summer. Caribou live in herds of thousands which presents dangers for ...
