Are there any animals that migrate south for the summer and north for the winter?

I mean northern hemisphere animals - do any seek out extremes of temperature like this?

There is one in the Southern Hemisphere. Emperor Penguins migrate further inland in early autumn (March) for breeding. After the females lay the eggs, the males stay there during the winter while the females go back to sea to feed. In spring, the females return to feed the chicks, while the males go to shore to feed themselves.
