1. Seaweed and Algae: Seagulls might occasionally consume seaweed or other types of algae that grow on the shoreline or in shallow waters.
2. Grass: Seagulls have been known to peck on grass, especially if they find insects, snails, or other invertebrates living in the grass.
3. Berries: Some seagull species may occasionally eat berries, such as blueberries or cranberries, if they are available in their environment.
4. Seeds: Certain types of seagulls may consume seeds from plants, particularly seeds from grasses or other plants growing near their habitats.
5. Fruit: Although not a significant part of their diet, some seagulls may consume fruit if they come across it. For instance, they might eat fallen fruit or berries if they find them.
It's important to note that while seagulls may occasionally eat plants, their diet is primarily focused on animal-based food sources. Their consumption of plant material is usually limited to specific times or locations where plant foods are available and their primary food sources may be scarce.
