So far, we have written several posts about our red wolves here. While most of them have discussed our wolves’ health, we have also shown some video of great interactions with enrichment, as well as talking about their annual physicals. However, there is an abundance of information to be shared about this critically endangered species, and a good place to start is with their history.
Red wolves (picture left

Their presence in the wild was essential for keeping other wildlife populations healthy and balanced, such as white-tailed deer and raccoons. Unfortunately, red wolves were believed to be a nuisance to farmers who thought they were a danger to livestock, while others wanted to eradicate them simply out of fear for their own safety. These misconceptions eventually caused a bounty to be placed on them, meaning anyone that could prove they had killed a red wolf received a cash reward. The onset of increased hunting, coupled with loss of habitat and the threat of hybridization, forced this species to the brink of extinction. By the time the Endangered Species Act was started in 1967, wild red wolf sightings were few and far between. They were promptly added to the Endangered Species List, and throughout the 1970’s all of the remaining red wolves were collected from the wild to start a successful breeding program.
However, red wolves had begun breeding with coyotes (picture right
) as their numbers depleted in the wild. This led to red wolf-coyote hybrids that had to be identified and removed from the remaining wild population. The result was 17 full-blooded red wolves, 14 capable of breeding, from which to pull the species back from near extinction. In fact, they were classified extinct in the wild
Compare the two pictures above: do you notice the similarities between the coyote and red wolf? Look for a later post to learn how scientists managed to tell coyote hybrids apart from red wolves in the 1970’s when DNA testing was not available.
