Abstract

The ACAP Seabird Bycatch Identification Guide is primarily intended for use at sea by fisheries observers to assist in the identification of albatrosses and some commonly caught petrels and shearwaters killed in longline operations. Where possible, species identification is based on those characteristics that are most likely to be preserved in dead birds that may have been underwater for long periods of time. In most cases, these are primarily bill size and colour. Because dead birds may look quite different to live birds, where possible, the photos included in this guide are of dead birds. In some cases it will not be possible to identify a bird to a single species, but it should be possible in most cases to narrow the identification down to two or three possibilities. For species with a restricted range, distribution maps have been added to eliminate them from the possible options.
