How does the physical size of Waimanu compare to a modern Emperor Penguin?
Answer
Comparable in size, though perhaps slightly smaller
Waimanu reached heights between 2 and 3.2 feet and weighed between 22 and 66 pounds. These measurements place the bird in a size class very similar to the modern Emperor Penguin, though anatomical assessments suggest it was likely on the smaller end of that spectrum compared to the largest of today's penguin species.
