NOEL KING, HOST:
Good morning. I'm Noel King. Congratulations to the Hoiho penguins. They won New Zealand's bird of the year poll. Also called the yellow-eyed penguin, they're known to be anti-social. They don't like to nest around other penguins. But when they do socialize, they do so by screaming.

KING: Savor the victory, Hoihos, and keep on yelling. Transcript provided by NPR, Copyright NPR.
