Are Northern Cardinals strictly sunflower seed consumers?
Answer
No, they are omnivores with a significant appetite for invertebrates.
While sunflower seeds are prominent at feeders, cardinals are fundamentally omnivores. Their diet is balanced; seeds and fruits form a major part, but they actively seek out and consume invertebrates like bugs and worms, especially when protein demands, such as during breeding season, are high. This mixed diet is essential for their overall nutritional needs, balancing carbohydrate and fat intake from seeds with the high protein derived from animal sources.
