The Humboldt penguin is a medium-sized penguin native to the coasts of Chile and Peru. It is easily recognized by its black and white plumage, with a distinctive band of black feathers across its chest. These penguins typically grow to about 24 to 28 inches tall and weigh between 8 to 14 pounds. Humboldt penguins are known for their social behavior, often found in large colonies. They primarily feed on fish, squid, and crustaceans, using their excellent swimming skills to catch prey. This species is currently classified as vulnerable due to habitat loss and overfishing in their natural environment.
