A Birder's List of Birds of the World

A complete field checklist, stapled paperback field size. Quite possibly the only comprehensive world checklist that you can carry in the field with you. Includes a complete taxonomic-order list of families and subfamilies, but the list is in alphabetical order by group name. The list includes codes for regions and subregions where the bird occurs and an alphanumeric code for order, family, and subfamily.
