Arctic Foxes save for lean times

Arctic foxes create "nest eggs" each year to prepare for leaner times, according to a new study.

Like squirrels gathering nuts for the winter, the small foxes hoard bird eggs in case there's not enough of their favorite prey—the collard lemming—to go around in the spring.

The stored eggs can last for up to a year after being buried, thanks to the Arctic permafrost and natural preservatives inside the eggs.
