Sometime in July, a male mountain lion made his way crossing the 405 freeway in the Sepulveda Pass, according to The National Park Service.

Known as P-61, it was the first time during the course of the 17-year study that a GPS-collared lion crossed the 405 freeway.

“Although P-61 successfully crossed the 405, his feat is a reminder of how challenging Southern California’s road network is for mountain lions and other wildlife, as well,” said Jeff Sikich, biologist for Santa Monica Mountains National Recreation Area in a press release. “Others haven’t been so lucky.”

The most well-known example was P-22 crossing the 405 freeway but he wasn't collared. 

“It will be interesting to see if P-61 stays in the area, whether he decides to challenge the uncollared lion, or if he heads back to the other side of the freeway,” said Sikich in the press release. “Although it’s a relatively small area of habitat, it’s certainly larger than the Griffith Park area and does have a patchwork of natural areas.” 

P-61 was first captured and outfitted with a GPS collar in October 2017.

He weighed 119 pounds at his most recent capture and is believed to be approximately four years old.
