Chinstrap penguins

Sometimes when stuck with family, it might be tempting to give them an earful, like this chinstrap penguin is doing here on the South Sandwich Islands, in the South Atlantic Ocean. This particular penguin gets its name from the black band beneath its head. Unlike other penguins, Chinstraps prefer nesting on rockier slopes and are an aggressive species among their kind. In their natural habitat, they primarily feed on krill and face threats from leopard seals, their main predator. Catch them in their natural habitat along with Adélie and macaroni penguins. You can tell them apart from the others by the ring—or chinstrap—around their neck and by their loud and harsh call that sounds like quite the grievance indeed.
