Where are chinstrap penguins found?
It may sound like a typical morning in New York City, but the setting is Antarctica, and these passengers are penguins with chin straps. Named for the facial markings that resemble a helmeted chin strap, these flightless, two-foot-tall birds live in and around Antarctica and nest in busy areas called colonies. Many chinstrap colonies are home to millions of people and many resemble man-made urban centers. The seabirds that live in it are some of the best in town.
A sprawling city is bustling with the loud noise of the morning rush hour. Passengers rushed past each other. Suddenly, a passenger bumps into another passenger and starts screaming.
You don’t just have to find a predator for the chinstraps. They also had to watch out for thieves within the colony. That’s because penguins are always trying to steal rocks from each other’s nests. The animals fend off thieves by attracting them with their wings. Why does a chin strap protect his stone? The rocks protect the eggs and chicks from melting ice, which can be fatal for the developing offspring if they enter the nest.
If the parents don't take care of the chicks, they go to work. Is it the parents’ job? Fishing for the family. To get from their homes to the ocean, chin ropes run along “roads” that have long been used by members of the colony, turned into old pavement. Like city streets, they are often crowded. After traveling beyond the penguins’ nesting grounds, they reached the colony’s “food market” on the beach. There, they jump into the water in search of shrimp-like krill. (Play Hammer Curls!)
In late January, the offspring are released in groups so that both mother and father can forage. The groups—which are like community orphanages—come together to have fun. Eventually, the chicks swarm together in the colony. When they are about eight weeks old, they shed their gray, shaggy coats to get their black and white feathers. The chicks then jump off on their own, heading out to sea to learn how to catch food.
By the end of March, these penguin cities were empty. The chin straps spent the next few months at sea. The following November, the birds return to build their city. The new residents will have children, and the parents will once again prepare their children for life in the great city.
