The first comprehensive study of the Puerto Rican Parrot tells the story of efforts to save a population once described as doomed to extinction. Provides information about human events surrounding the bird's history starting with Christopher Columbus in 1493, about other parrots, and about other species that live around the parrot and in various ways interact with it. The authors present their scientific results and often add vivid, descriptive accounts of bird- human encounters, scenery, and adventure. The first two chapters comprise a review of the population status of parrots in general, and provide an historical perspective for the decline of the Puerto Rican Parrot. Chapter 3 is devoted to a discussion of the species' taxonomic relationships to other West Indian parrots. Chapter 4 describes the Luquillo Forest of the Sierra de Luquillo, where the 30-odd remaining wild Puerto Rican Parrots live. Chapters 5-8 deal with behavior, food habits, nest sites, reproductive behavior, and the species' natural enemies. Chapter 9 quantifies the decline of the bird. Chapter 10 gives details of the history of conservation efforts. Chapter 11 discusses the captive breeding program, and chapter 12 brings us up to date on the status of the population. The guts of this book are a highly quantified account of the Puerto Rican Parrot's natural history and attempts at conservation in the face of many factors of habitat destruction, direct human pressure in the form of hunting and capture for the pet trade, conflict with natural enemies such as the Pearly-eyed Thrasher (Margarops fuscatus) which usurps nest cavities, and Red-tailed Hawks (Buteojamaicensis) which prey on adults (including captive- reared birds released to build up the wild population). The authors began their study in the early 1970s, pessimistic about wild survival of this species, and they end this book with a show of cautious optimism. The wild flock has ceased to decline (though it shows no great promise of multiplying); release of captives has had disappointing success but shows promise for the future; and the Luquillo Forest is a stable environment now, with considerable protection from poachers. If tropical storms do not level the whole scene, and if competition and/or hybridization with other introduced parrots do not become inhibiting factors (they are not now), there is hope.
