How much does a loon eat a day?

A common loon typically consumes about 1 to 2 pounds of food per day, which can vary based on the availability of prey and the bird's energy needs, especially during the breeding season. Their diet mainly consists of fish, crustaceans, and other aquatic invertebrates. To maintain their body condition for diving and swimming, they need to consume a significant amount of food relative to their body weight.
