Joe Rogan Experience #954 - Justin Brown

Episode Summary

Main Topics Discussed

• Urban Coyote Ecology: Guest Justin Brown, a biologist, discussed his extensive work tracking and studying coyotes in densely populated areas of Los Angeles, including downtown.
• Coyote Diet & Adaptability: The conversation explored the surprising omnivorous diet of urban coyotes, relying on fruits, rodents, insects, and human trash, showcasing their incredible adaptability.
• Human-Coyote Interactions: Joe and Justin delved into common conflicts, protective behaviors during pupping season, and the importance of discouraging coyotes from becoming habituated to humans.
• Wildlife Research Methods: Details were shared about the process of capturing and collaring coyotes without tranquilizers, and using citizen science for scat analysis.
• Mountain Lions in LA: The discussion touched upon the presence of mountain lions, particularly the famous P22 in Griffith Park, and their remarkably small urban home ranges and diets.
• Coexisting with Predators: The overall theme revolved around the challenges and realities of large predators living alongside humans in urban environments, and how human behavior impacts these interactions.

Key Insights & Memorable Moments

• Coyotes are remarkably urban-adapted: Justin recounted tracking a coyote for nine months in downtown LA, living among vacant lots with minimal complaints from residents.
• Docile Coyote Capture: A surprising revelation was that coyotes, unlike raccoons or bobcats, often become very docile during capture for collaring, allowing biologists to work with them without tranquilizers.
• Coyote Intelligence: Joe shared a vivid story of a coyote tricking his Mastiff to knock over a chicken coop, while Justin noted coyotes "looking both ways" before crossing busy roads.
• P22's Unique Existence: The discussion highlighted the extraordinary case of mountain lion P22 living a full life within Griffith Park's limited 4,300 acres, an unusually small range for a male mountain lion, without conflicts with people.
• Scare Them Off: Justin emphasized that a key to reducing human-coyote conflicts is for people to actively scare off coyotes rather than tolerate their presence or, worse, feed them.

Notable Quotes or Revelations

• Justin Brown on urban coyote resilience: "They're able to live in some of the most Urban environments we can imagine."
• Regarding managing coyotes: "It's really all about us. It's more about managing people getting people to quit feeding them or quit... scare the stupid coyote off."
• On collaring coyotes: "We don't tranquilize them... they actually go very docile."
• Joe Rogan's humorous take on a coyote sighting: "He was sitting behind their yard looking at their wife in the jacuzzi. Oh Jesus Christ. Sky's a pervert. Yeah, exactly."
• On P22's territory: "He's got the smallest home range of any mountain lion male mountain lion that we've know of... 4,300 [acres] compared to about 75,000 Acres."

Overall Themes

• Urban Coexistence: The central theme is the unexpected and ongoing integration of large wild predators into densely populated urban landscapes, challenging traditional notions of wildlife habitats.
• Adaptability of Wildlife: The episode powerfully illustrates the incredible behavioral and dietary flexibility of animals like coyotes and mountain lions, allowing them to thrive in human-dominated environments.
• Human Responsibility in Wildlife Management: A recurring message is that human actions (e.g., feeding, tolerance, trash management) significantly influence wildlife behavior and conflict levels, placing responsibility on people to manage interactions.
• Challenging Misconceptions: The discussion aimed to demystify urban predators, showing that they are often less aggressive than feared, and more driven by instinct and opportunity.
