Available in PDF, EPUB and Kindle. Book excerpt: Twenty-three natural and dredged material islands were examined in seven locations from Anacortes, Washington, to Coos Bay, Oregon, to establish the relationships between plant communities and use by colonial nesting waterbirds for both types of islands, as well as the actual bird use of dredged material islands in the Pacific Northwest. Nine islands were found to be used for nesting by one or a combination of glaucous-winged gulls, western-glaucous-winged (hybrid) gulls, ring-billed gulls, Caspian terns, and common terns. Colonies of great blue herons were found on two islands 61 and 97 km from the mouth of the Columbia River. Habitat maps were prepared for each island studied and detailed floristic descriptions of each bird colony evaluated. Colony location, breeding phenology, and nesting success were analyzed with respect to existing flora, environmental stress, island physiography, and human disturbance. Results showed that although dredged material deposition influenced an island's physical dimensions, topography, and substrate, plant communities were physiognomically similar to natural islands. Seabird colonization occurred irrespective of dredging history.

Available in PDF, EPUB and Kindle. Book excerpt: The maJonty of the chapters in this volume are structured to include a balance between literature review, original data, and synthesis. The research approaches taken by the authors are generallyof two kinds. One centers on the long-term, in-depth study of a single species in which many aspects of its natural history are examined in detail. The other is a comparative one which involves investigating particular questions by examining species or by comparing groups of species that may include taxonomic andjor ecological affinities. Most of the chapters concern obvious aspects of breeding behavior including habitat selection, the effects of age on breeding, communication, mating systems, synchrony of breeding activities, development of behavior, prefledging parental care, and postfledging parental care. Of these topics, many relate directly to the advantages and disadvantages of coloniality-a conspicuous behavior pattern in marine birds. As such, they provide para.picuou for the further study of coloniality and the social behaviorof many other animals. Other important areas of marine bird breeding behavior (such as courtship behavior, antipredator behavior, information transfer) have not been included because of space limitations. Since man's encroachment on the seashore and continental shelf poses certain threats to marine birds, a volume elucidating various aspects of their biology has multiple uses. As weil as being of value to ornithologists, the volume should be useful to managers involved with coastal planning.
