Extinct animals of BC:

2. Vancouver Island Wolverine. BC. Mammal. 1992
3. Lewis's Woodpecker, Georgia Depression Population. BC. Bird. Mid 1970's.

Animals no longer in Canada but who still exist:

Dawson Caribou. BC.

Some animals have left BC but still live in other parts of Canada:

Greater Sage-grouse. BC.
Yellow-billed Cuckoo. BC

'The distribution of many animals in Canada has shrivelled. Some wildlife species have even vanished entirely from a province or the whole country.

Thirty mammals, birds, reptiles and fish that used to live in Canada no longer do. Biologists suspect that another four species or subspecies of animals which haven't been seen recently may also be gone.

Some of these animals continue to survive in other countries, particularly the United States, and so are considered extirpated from Canada. Many others are globally extinct.

Several of the extinct animals were isolated or endemic to Canada such as Dawson caribou on BC's Queen Charlotte Islands, and Banff longnose dace, a fish which occupied only one marsh. Others, including eastern elk and Atlantic gray whale, were exterminated from their entire range that extended well outside of Canada.

Besides these, at least another 25 species and subspecies of vertebrates: mammals, birds, reptiles, amphibians and fish are depleted and now considered extirpated from one or more provinces, although they still live elsewhere in Canada. The lack of any recent confirmed local evidence of another ten birds and five mammals suggests that they might also have died out from at least one province in their former range."

"Wolverine
Gulo gulo

There is probably no other animal that has generated as much legend for its size as the Wolverine. Males can weigh almost 15 kilograms, which is much less than many family dogs, but there are reports of Wolverines taking down deer. Their ferocity when cornered is awesome. Wolverines are not common, and this, along with their secretive habits, may be why they are rarely seen. They live in forested areas, where they capture small mammals and birds.

Wolverines depend heavily in winter on carrion, and their jaws are incredibly strong, and well suited to feeding on frozen animal carcasses. They are well known, too, for their predation on trappers' catches, and cached provisions. The pelt of the Wolverine itself has traditionally had a unique value - it is considered the best fur to trim a parka hood, because it sheds frost without becoming wet.

Wolverines mate in early summer, but implantation of the egg is delayed until winter. After a gestation of about two months, the litter of two to five young is born in spring, usually in a den under rocks or tree roots.

And if you should ever see one, it will be short legged, and dark all over with two buffy stripes running along its sides and joining over its tail. Wolverines are scattered in suitable habitat throughout British Columbia, except the Queen Charlotte Islands. The Vancouver Island race is little known, and sight records are very few."
