What observation is made about the head size of the larger Waimanu species?

Answer

The head was relatively small compared to the body

Based on skeletal reconstruction, the larger Waimanu species possessed a head that was relatively small in proportion to their overall body size. This is one of the distinct morphological features that helps distinguish these ancestral forms from their modern descendants, even though they share the general penguin lineage.
