Erect-crested penguin eggs (2nd of 2)

Erect-crested penguin eggs

Erect-crested penguins lay two eggs each year, the second egg being 85% heavier than the first. However, they only ever rear one chick. Almost always the chick hatches from the second egg. This phenomenon is a trait of all crested penguins.
