African Penguins Have a Bare Patch Above Their Eyes.

African penguins have a patch of bare skin above each eye. These bare patches are designed to help them cope with the high temperatures along the southwestern coast of Africa, where they live. As the penguin gets hotter, more blood flows to these patches, where it is cooled by the surrounding air. This helps to cool the penguin’s body overall. Due to the increased blood flow, these bare patches appear pinker when the penguin is warmer.
