A group of gray wolves in Canada. Before a wolf pack recently migrated to Colorado, gray wolves were last known to live in the state in the 1940s.

Colorado Will Reintroduce Endangered Gray Wolves This Month

In 2020, voters narrowly passed a measure in favor of wolf reintroduction, and now, wildlife officials are about to begin the controversial effort

Throughout the spring, biologists captured this behavior among adult members of Mollie's Pack using a trail camera.

When they can't bring food back to the den, the animals retrieve bones, sticks and antlers for their young to chew on—and biologists captured it on video

Since their reintroduction in 2018, the wolves have rebounded from just two inbred individuals to 31 healthy animals

Large felids such as lions and tigers cause more deaths than other predators like bears and wolves. Most fatal felid attacks occur in low-income areas and are predatory, with humans stalked as prey.

Researchers have located a genetic mutation associated with smaller dogs.

Mutation That Gave Us Tiny Dogs Found in Ancient Wolves

The genetic factor that plays a large role in determining canine body size was around thousands of years prior to domestication

After comparing all genomes, the researchers found that the Japanese wolf is part of an evolutionary branch of wolves that arose 20,000 to 40,000 years ago. Some of the wolves from this branch evolved into the Japanese wolves while others branched off and gave rise to modern dogs.

Ancient Japanese Wolves May Be the Closest Wild Relative of Modern Dogs

The results challenge previous theories about the origin of dog domestication

The new gray wolf pups in Colorado have yet to be photographed, so for now you'll have to make do with this bright-eyed pair.

A new study in Wisconsin suggests the predators keep prey away from roads, reducing crashes by 24 percent

Supporters of the law argue wolves are a threat to livestock. However, only 102 sheep and cattle were killed by wolves last year. Idaho loses about 40,000 cattle to non-predator factors each year.
