Bear Feeding Behavior and Ecology

The video explores the eating habits of grizzly bears, focusing on why they often abandon parts of their salmon catch. It explains that bears prioritize high-calorie parts like skin and brain due to the energy cost of processing food. This behavior is compared to other animals, highlighting how natural selection and instincts guide these decisions. The video concludes by noting that discarded fish parts contribute to the ecosystem.
