A Raft of Penguins at the Central Park Zoo

A group of penguins in the water is called a raft—on land, they become a waddle. Four species of the flightless birds—chinstrap, gentoo, king, and macaroni—inhabit the Polar Circle exhibit (pictured, with gentoos, above) at the Central Park Zoo, whose work supports the protection of animals in the wild. (Advance timed-entry tickets, available via centralparkzoo.com, are required.) Lucky visitors might spot a recent arrival: Marinara, the first macaroni-penguin chick to hatch at the zoo.
