Since the passage of the Endangered Species Act in 1973, a number of plans have been developed to study condors in the wild and in captivity, create a safer natural environment for the birds, and educate the public. In her latest work about endangered wildlife, Arnold describes the efforts of the California Condor Recovery Team. Her lucid and interesting account of the history of condors emphasizes the factors that led to the birds' near extinction and explains in great detail the measures that have been taken to reestablish a significant condor breeding population. Wallace's photographs are magnificent. They capture the unusual beauty of the creatures and document the processes of procuring and incubating eggs, rearing the hatchlings, and reintroducing mature condors into the wild.
