opportunivore

An opportunivore is an animal that will eat whatever food is available and easily obtainable at a given time. This dietary strategy is distinct from a specialist feeder, which has a narrow range of preferred food sources, or a strict herbivore, carnivore, or omnivore. Opportunivores are characterized by their dietary flexibility and their ability to adapt to changing environmental conditions and food availability.

The feeding habits of opportunivores often reflect seasonal changes, geographic location, and the presence of specific prey or food items. For example, an animal might be primarily herbivorous but will consume insects or carrion if they are readily available and provide a nutritional benefit. This opportunistic approach allows them to survive in environments where food sources can fluctuate significantly.

Many animals exhibit opportunistic feeding behaviors to some extent, even those classified as primarily belonging to another dietary group. This includes a wide range of species, from insects and birds to mammals. Their ability to exploit a variety of food resources enhances their resilience and adaptability within their ecosystems. The term "opportunivore" highlights this flexible and opportunistic aspect of their diet, emphasizing survival through resourcefulness rather than strict dietary adherence.
