[00:00:00]When an eagle decides to land on frozen water, it does not hesitate. Ice that would kill a human in minutes means nothing to [music] this predator. But how is that possible? A bald eagle stands on frozen lakes for hours.

[00:00:13]>> [music] >> Temperatures dropping below minus 30, wind slicing across exposed talons, yet the eagle feels nothing. No pain, no damage, no frostbite. The secret is hidden inside [music] its legs. Eagles have almost no muscle tissue below the knee. Only tendons, bone, and tough scaled skin. There is very little blood and very little warmth to lose. But the real [music] weapon is something called countercurrent heat exchange. Warm blood flowing down [music] from the body passes directly beside cold blood returning from the feet. The heat transfers between [music] them before it ever reaches the ice. By the time blood touches the talons, it is already cold.

[00:00:53]So there is nothing left to freeze.

[00:00:55][music] The feet stay just above freezing. The core stays warm. The eagle uses almost no energy. [music] This is why an eagle can stand motionless on ice for hours watching, waiting, scanning the water below for the exact second a fish rises too close to the surface. Cold does not weaken the eagle. Cold is its hunting ground. And when it finally moves, the strike is already over before the prey understands what happened.
