Flight of the Iguana

Quammen's columns in Outdoor Magazine are famed as an entertaining source of offbeat information. In this collection, he casts sidelong glances at creationism and extinction, at giant earthworms and Canada geese. But he takes a direct view at the plight of Salvadoran refugees and at the Sanctuary Movement; he accompanied one group on a dramatic journey across the Sonoran desert. Quammen examines the special problems of species survival on islands (and tells us what is happening to the birds of Guam); he discusses the unusually small gene pool of cheetahs and how the Papago Indians survive in desert lands. There is a piece about visiting the Okefenokee Swamp, while the title essay is set in the Galapagos. Readers who enjoyed Natural Acts will find Quammen's new collection equally interesting. (June)
