In one study, wolves detected moose using scent ten times, vision six times, and once by following tracks in the snow. Their vision is as good as a human's, and they can smell prey at least 2.4 km (1 + 1 ⁄ 2 mi) away. One wolf traveled to a herd 103 km (64 mi) away. A human can detect the smell of a forest fire over the same distance from ...
The biting ticks cause a lot of discomfort for the moose, so they try to get the ticks off their bodies by biting off their hair, and rubbing up against trees. This preoccupies moose, and keeps them from browsing for food, which can lead to malnutrition. Compounded with blood loss, moose weakened by ticks are easier for wolves to kill. [41]
When hunting moose, wolves mainly kill calves and old moose when fleeing. Usually the hunting success rate for moose is 10% in one hunt, and a pack usually kill a moose every 5 to 6 days to eat for 2 – 3 days. Moose are more likely to stand their ground than caribou, which tend to flee, decreasing their survival rate. Wolves usually kill a ...
During winter, they primarily eat the carcasses of animals that have died of natural causes and the carcasses of moose and caribou left by wolves and hunters. The rest of the year their diet consists of smaller animals, such as voles, squirrels, snowshoe hares, and birds. On rare occasions, wolverines may kill moose or caribou. [34]
The wolverine's questionable reputation as an insatiable glutton (reflected in its Latin genus name Gulo, meaning "glutton") may be in part due to a false etymology.The less common name for the animal in Norwegian, fjellfross, meaning "mountain cat", is thought to have worked its way into German as Vielfraß, [5] which means "glutton" (literally "devours much").
There are around 300 wolverines left in the wild in the US, and could face extinction due to the melting of their habitat
Wolf populations in North America commonly sustain annual harvests or natural mortality rates of 20–40% without experiencing a year-to-year decline in numbers. [64] Sarah Palin of Alaska in 2007 approved the use of this provision in the law to shoot wolves and bears while flying for the purpose of protection of property. [66]
The greatest danger to people from moose is car collisions. From 1995 to 2006, there was an average of one collision a year of a moose and an automobile across the state, although in the first half of 2007, there were four, including one in June on the Merritt Parkway in Stamford. Unlike deer, moose that feel threatened tend to stand their ...
