The race to save the world's rarest bird: the discovery and death of the poouli (1st ed.)

Thirty years ago researchers discovered a previously unknown species of bird in the rain-soaked and remote mountains of Hawaii.

As they studied the creature -- which sported a black mask and was called the po'ouli -- they soon learned that its population was shrinking quickly, and they worked frantically to find out what was killing the species and how they might prevent its extinction.

This fast-paced account of their work, done in one of the world's most inhospitable environments, describes a stirring fight for survival.

It also illustrates the challenge of protecting endangered species in a rapidly changing world.
