ONTONAGON COUNTY, MI — Two cougar cubs found this spring in the Upper Peninsula remain alive and traveling with their mother, a confirmation that Michigan wildlife officials say represents a historic milestone for natural reproduction.

The Michigan Department of Natural Resources said Thursday, Dec. 18 that a trail camera photo taken this month shows an adult female cougar walking down a snowy trail in central Ontonagon County followed by two juvenile cougars estimated to be roughly a year old.

The same cubs were first documented in early March when motorists photographed two small kittens along a western U.P. road.

“This is a historic confirmation for Michigan since it is the first time in over 100 years that verified cougar reproduction has occurred east of the Mississippi River and possibly even east of the Missouri River,” said Brian Roell, DNR large carnivore specialist

Until this year, genetic testing and other evidence indicated that nearly all confirmed cougars in Michigan were transient adult males believed to have traveled east from established populations in the western states.

The presence of cubs confirms at least one breeding female is now on the landscape, though officials say that doesn’t mean Michigan has an established breeding population.

Cougars are native to Michigan but were essentially hunted out of the state by the early 1900s. The DNR has confirmed about 168 cougar sightings since 2008, although it says most of them are of the same animal being reported by multiple sources.

All confirmed sightings have been in the Upper Peninsula.

Cougar sightings have been increasing in recent years alongside the proliferation of trail cameras. This marked the third consecutive year of record-high cougar sightings in Michigan. As of late November, the DNR had confirmed 26 sightings statewide in 2025.

The state verified the first confirmed vehicle collision with a male cougar on Nov. 15 in northern Houghton County.

The DNR said it verified the new cubs sighting image after a private landowner submitted a trail camera photo taken Dec. 6. Biologists enhanced the nighttime image and confirmed the presence of three cougars. The sex of the cubs is unknown.

Cougar cubs typically stay with their mother for up to two years and Roell said their chances of survival are relatively high because female cougars invest heavily in raising their young. The absence of an adult cougar in March had raised concerns about their survival. He is surprised the kittens weren’t seen on any other trail cameras since this spring.

“These kittens will stay with their mom through this winter and possibly even into next winter,” Roell said.

State officials did not release the exact location of the latest sighting. Cougars are listed as endangered in Michigan. It is illegal to hunt or harass them or attempt to locate dens.

Anyone who encounters evidence of a cougar should keep their distance, avoid disturbing the area and report sightings to the DNR.

The DNR said other states, including Nebraska, have also reported increases in cougar sightings.

Cougars need large territories because they are solitary ambush predators that rely on deer and other large prey, which leads to low population densities. Even states with the largest cougar populations generally have just a few thousand of the animals.

“This isn’t an animal that is ever going to become very numerous,” Roell said. “They’re going to remain rare on the landscape regardless of whatever happens with them here in Michigan.”
