Penguins in the cold

A recent article in Wired shows some fabulous infrared images of Emperor Penguins. Somewhat surprisingly, large sections of an Emperor Penguin’s body surface are cooler than the surrounding air. Their eyes, their flippers, and the tops of their feet stand out as hot spots.

Emperor Penguins survive the long Antarctic winter by huddling together, in temperatures that can drop to −40° — a theme I explored in my children’s book Penguin, which was so beautifully illustrated by Marion & Steve Isham.
