Where do long-distance migrants migrate?

What is the difference between short distance migration and long distance migration?

Short-distance migrants make relatively small movements, as from higher to lower elevations on a mountainside. Medium-distance migrants cover distances that span a few hundred miles.

These birds do not migrate as a flock but individually, covering distances of up to 64,000 km (39,767 mi). Recent tagging experiments suggest that birds breeding in New Zealand may travel as far as Japan, Alaska and California in a single year, which could add up to 74,000 km (45,981 mi).
