Birds of the World: Emperor Penguin

Aptenodytes forsteri.

The tallest and heaviest of all penguin species. A fascinating social bird endemic to Antarctica. They feed primarily on fish and sometimes crustaceans and squid. They swim to catch fish and can stay submerged as long as 18 minutes. Several adaptations allow this, including unique blood, and a control of its metabolism allowing it to conserve energy in low oxygen situations.

They are the only bird known to breed during the Antarctic winter. Traveling in groups to breeding territories. Females lay one egg which is incubated by the male. The average lifespan is 20 years though researchers have found some as old as 50. In large nesting sites mates communicate with complex and unique vocalizations.

Thanks again for looking at birds with me.
