Birds fly very efficiently, doing little work themselves, and gaining large amounts of energy from the atmosphere. Whether on local flights or migration, they have the freedom to fly anywhere they please. It is because of this that scientists have long been fascinated with how birds remain the ultimate aviators. Birds Never Get Lost includes reports of how bird flight has been studied in laboratories, as well as by flying with them. It also provides a comprehensive background of what distinguishes birds from other flying animals, past and present, from bats to pterosaurs.
