Grey wolf

Canis lupus

Also calledBheṛiyā (Hindi) · Gorg (Persian) · Dhiʾb (Arabic) · Láng 狼 (Chinese) · Ōkami (Japanese) · Börü (Turkic) · Maʼiitsoh (Navajo)

The largest wild member of the dog family and the ancestor of every domestic dog. Wolves live in family packs that cooperate to hunt animals far larger than themselves across the Northern Hemisphere.

The wolf, also known as the grey wolf or gray wolf, is a canine native to Eurasia and North America. More than thirty subspecies of Canis lupus have been recognized, including the dog and dingo, though grey wolves, as popularly understood, include only naturally occurring wild subspecies. The wolf is the largest wild extant member of the family Canidae, and is further distinguished from other Canis species by its less pointed ears and muzzle, as well as a shorter torso and a longer tail. The wolf is nonetheless related closely enough to smaller Canis species, such as the coyote and the golden jackal, to produce fertile hybrids with them. The wolf's fur is usually mottled white, brown, grey, and black, although subspecies in the arctic region may be nearly all white. Wikipedia

§1

What it can do

  1. iHunts cooperatively in packs to bring down elk, moose and bison
  2. iiHowls that carry for kilometres and help scattered pack members regroup
  3. iiiCan travel tens of kilometres in a day at a steady trot
  4. ivAs an apex predator, shifts the behaviour and numbers of prey, with knock-on effects on vegetation

In the field

Field marks

  • aLarge, long-legged dog-like animal
  • bUsually grizzled grey, but can be white, black or tawny
  • cBroad head and short, rounded ears
  • dTail carried low; long straight-line trotting gait
Voice
A long, low howl, often joined by the pack in chorus
Not to be confused with
Coyote is much smaller with a narrow, pointed muzzle and larger, pointed ears. Large domestic dogs can look similar; wolves have longer legs and narrow chests. Never approach on foot; watch from a vehicle, boat or hide, or with a licensed guide.
Where to see it
Lamar Valley, Yellowstone; Algonquin Provincial Park (public howls in late summer)
When
Resident; Yellowstone sightings best in winter and spring

Life & habits

Diet
Carnivore: deer, elk, moose, caribou, bison, smaller mammals; scavenges carrion
Habitat
Almost any habitat with enough prey, from Arctic tundra to desert
Size
25–80 kg; head-body 1–1.6 m
Lifespan
6–8 years typical in the wild; up to ~13; longer in captivity

A typical pack is a breeding pair and their offspring from the past few years. Young wolves leave to find mates and found new packs, sometimes travelling hundreds of kilometres.

In the old herbals & bestiaries

Woodcuts and engravings matched from the Source Library’s scanned books by name. Plates marked “relative” show a close kin rather than this exact species. Click a plate to read the page it came from, with translation.

Marginalia

Rome's founding legend tells of a she-wolf suckling Romulus and Remus, cast in the bronze Capitoline Wolf. Turkic tradition traces the Ashina dynasty to the she-wolf Asena, and Norse myth gives the end of the world to the wolf Fenrir.

Curiosity

The 1995–96 reintroduction of wolves to Yellowstone changed how elk used the park, a famous case study of how one predator can reshape an ecosystem.
