The species accounts are arranged by family within each status category - recently extinct, extirpated, endangered, threatened, rare, species of special concern, and status undetermined. Each account contains detailed sections on taxonomy, description, population size and trend, habitat requirements and trend, vulnerability of species and habitat, causes of threats, responses to habitat modification, demographic characteristics, key behaviours, and conservation measures taken and proposed for the species. Each also includes a range map, an extensive section of literature cited, and a synthesis and discussion of the ecology, habitat requirements, and anthropogenic factors affecting the species' survival, especially in Florida. In addition, 61 photographs and 4 drawings accompany the species accounts. Much of the information on the Florida population status is presented here for the first time and is based on previously unpublished research. This volume is an essential reference for biologists, conservationists, environmental consultants, educators, and amateur ornithologists interested in the endangered and threatened birdlife of Florida.
