Dive into the wild world of beasts with the latest episode of “Ologies with Alie Ward,” as guest Dr. Rae Wynn-Grant brings her expertise on carnivorous animals to the table. Ward and Wynn-Grant embark on a fascinating journey through the forests of the central California coast, uncovering the secretive lives of black bears and mountain lions. Their conversation reveals the pivotal role these predators play in maintaining the delicate balance of their ecosystems and how their feeding habits have broader implications for conservation efforts.
From the extraordinary olfactory capabilities of bears to the intelligent social conducts of wolves, this episode delves into the intricate details of carnivore behavior and physiology. Wynn-Grant deftly explains the diverse dietary habits within the Carnivora order, dispelling common misconceptions by illuminating the nuanced differences between obligate and omnivorous species. Join Ward and Wynn-Grant as they explore the cognitive prowess of these majestic animals, their adaptation strategies, and the profound impact that food security has on their survival and interpersonal interactions.

Dr. Rae Wynn-Grant's work in the central coast of California centers around tracking the movements and behaviors of black bears and mountain lions. Her research involves hiking through remote locations to observe these carnivores firsthand. By studying how far bears can travel for food, like finding marine animal skeletons deep in the forests and bear tracks on beaches, Wynn-Grant provides insights into carnivore feeding behaviors and the overall health of the ecosystem. Her findings underscore the importance of these predators in maintaining ecological balance and signal where conservation efforts should be directed to protect vital habitats.
Dr. Rae Wynn-Grant reports that large carnivores, particularly bears, have an extraordinary sense of smell that guides their foraging decisions. They can detect the scent of potential meals from several miles away. This ability is not only indicative of their physical capacities but also influences their behavior in searching for and selecting food sources across vast distances.
Wynn-Grant, in her discussions with Alie Ward, explains the difference between obligate and omnivorous members of the Carnivora order. While all have physical traits for a meat-based diet, not all strictly consume meat. Pandas, for example, eat bamboo but can digest meat when necessary. Many carnivores like bears also eat plant-based foods to diversify their nutrient intake. Wynn-Grant touches on the offensive smell of carnivore feces, primarily due to the digestion of flesh. She highlights an intriguing aspect of bear physiology during hibernation, where they recycle waste internally to avoid defecating, allowing them to conserve energy and survive the winter without leaving their dens.
Wynn-Grant points to the large brain-to-body size ratio, particularly in bears, as a marker of intelligence among carnivores. She underscores the cognitive abilities of these creatures by referencing the historical interaction between wolves and early humans, which showcases their potential for learning and adaptation. She implies that the food security of carnivores can heavily influence their behavioral patterns. For instance, well-fed lions demonstrate reduced aggression and territorial behaviors, reflecting how the provision of basic needs impacts carnivore behavior and cognition.
1-Page Summary
Dr. Rae Wynn-Grant sheds light on the critical work of carnivore ecologists through her research on the central coast of California, revealing the intrinsic significance of these animals to ecosystem health and the importance of conservation efforts.
Wynn-Grant devotes much of her time to hiking through remote locations to track the movements and behaviors of black bears and mountain lions. Her research has led to intriguing observations, such as finding skeletons of marine animals well into the forest and bear tracks on beaches, which informs their understanding of these carnivores' feeding patterns.
Carnivores play a vital role as top predators within food chains, making them essential for maintaining balanced and healthy ecosystems. Through her research at a nature preserve, Dr. Rae Wynn-Grant highlights the importance of documenting whether the reliance on marine animals is an innate or newfound feeding behavior for ...

Carnivore Senses for Detecting Food
Dr. Rae Wynn-Grant and Alie Ward delve into the eating habits of carnivorous animals and the digestion process that accompanies a diet rich in meat.
Wynn-Grant clarifies that the Carnivora order of mammals includes animals with certain physical traits like sharp teeth and claw, and a gut microbiome capable of processing meat. However, not all creatures in this group strictly consume flesh. She points out that pandas, part of the bear family and therefore classified as carnivores, predominantly eat bamboo but have retained the physical and digestive capacities to process meat if needed.
Wynn-Grant suggests that the ancestors of modern pandas may have been more traditionally carnivorous, eating insects or hunting prey. Beyond pandas, omnivores within the carnivora order can have plant-heavy diets thanks to diverse eating practices—for example, bears, coyotes, raccoons, and possums that eat a mix of meat, roots, tubers, fruits, grasses, and honey, aiming to accumulate fat from multiple food sources.
During their discussion, Ward inquires about the particularly foul odor of carnivore poop. Wynn-Grant responds that this unpleasant smell comes from the waste product of digested flesh. She doesn't specify any particular species or variance in odor intensity regarding different diets, such as bears con ...
Carnivore Diet and Digestion
Dr. Rae Wynn-Grant discusses various aspects of large carnivores that suggest they are among the smartest mammals, due to characteristics such as a high brain-to-body size ratio and the ability to learn from interactions with humans.
Large carnivores are generally seen as intelligent by human standards.
Particularly, bears are noted for having one of the largest brain-to-body size ratios of any land mammal, which is a common indicator of intelligence in the animal kingdom. This significant brain size, relative to their bodies, contributes to their standing as particularly smart among carnivores.
Another example of carnivore intelligence is seen in wolves. Wolves interacted with early humans, learning and replicating behaviors that were rewarded. This adaptive learning is what eventually led to their close relationship with humans and may have contributed to their evolutionary journey into becoming domesticated dogs.
