What dietary habit may American kestrels have?

American kestrels exhibit a diverse dietary habit that can indeed include a significant portion of insects, particularly during the warmer months when these prey are more plentiful. This flexibility in diet is a reflection of their adaptability, allowing them to thrive in a variety of environments.

While they primarily hunt small mammals and birds, their ability to consume insects showcases their opportunistic feeding behavior. This adaptability is essential for survival, especially in conditions where food availability varies. In contrast, being exclusively herbivorous, only carnivorous, or solely fruit-eating does not accurately represent the feeding behavior of American kestrels, as they do not rely on a single food source but instead utilize multiple sources to meet their nutritional needs.
