A map depicts the migration of 19 sooty shearwaters that were tracked using electronic tags in a recent study.

The research showed that the birds (pictured inset) migrated 40,000 miles (64,000 kilometers) a year, flying from New Zealand to the North Pacific and back. It is the longest animal migration ever recorded electronically.
