Mountain Lion Sparks Chaos in San Francisco Neighborhood During Hours-Long Capture

A wealthy San Francisco neighborhood was thrown into chaos Friday morning when a mountain lion was spotted prowling residential streets, prompting an hours-long standoff and a response from wildlife and animal control crews. The big cat was first seen near Ulloa Street and 44th Avenue in the Outer Sunset neighborhood, not far from the Pacific coastline.

Residents described hearing police bullhorns instructing people to remain indoors as news spread about the wild animal. Dramatic footage captured the mountain lion darting across front yards and creeping beneath windows. In one video, the animal was seen sprinting down the middle of the street between responding vehicles, evading capture.

Capture Efforts

Crews attempted to tranquilize the cat, but it evaded capture and retreated into thick bushes. The pursuit continued for approximately four hours before officials were able to tranquilize and capture the animal. Photos taken after the successful capture showed the tranquilized mountain lion lying on a stretcher.

The mountain lion was identified as a young male, estimated to be between two and three years old and weighing around 78 pounds. Fish and Wildlife spokesperson Peter Tira told SFGate that the animal was a "wayward young lion who got stuck in the Outer Sunset."

Tira explained that the young male was likely a dispersing lion that had recently left its mother in search of territory and strayed into the urban area. "It’s always a challenge, particularly for a young mountain lion, a male mountain lion especially," Tira said. "They’re out on their own for the first time and they kind of have to find their way in the world."

Public Safety Guidance

The first sighting was reported around 7:30 a.m., triggering an emergency alert from the city advising residents to stay away and warning them not to run if they encountered the animal. Officials advised anyone who came face-to-face with the cat to slowly back away, keep dogs on leashes, and scoop up children. If the animal advanced, residents were told to stand their ground, appear as large as possible, shout, and throw objects.

Release and Study

After its capture, researchers from the Santa Cruz Puma Project fitted the mountain lion with a satellite GPS tracking collar. Tira stated that the lion would become part of the department’s scientific study, contributing to research on mountain lion movements, behavior, and patterns in the wild. The project, a collaboration with UC Santa Cruz, focuses on mountain lion activity across the greater Santa Cruz Mountains region. The mountain lion has since been released back into its natural habitat in the Santa Cruz Mountains.
