What was the fattest puffin ever discovered?

Answer 1

The fattest puffin ever recorded was an Atlantic puffin that weighed approximately 1.5 kilograms (3.3 pounds). This unusual weight was noted during a study on puffin populations in the North Atlantic, where researchers found that the bird's weight was significantly above average due to an abundance of food sources at the time. Such extreme weight is rare and can impact the bird's ability to fly and breed effectively.
