The term "Avian Diet" refers to the eating habits and food preferences of birds. Different species of birds have unique diets based on their environment and physical characteristics. For example, sparrows often eat seeds and insects, while eagles primarily hunt small mammals and fish. Understanding these diets helps us learn about their roles in ecosystems. Birds can be classified into various dietary categories, such as herbivores, carnivores, and omnivores. Hummingbirds, for instance, are known for their nectar-based diet, while owls are strict carnivores. By studying avian diets, researchers can gain insights into bird behavior and conservation efforts.
