An introduction only to the twelve geographical regions you must visit to discover all of the regularly occurring ABA species - the maximum number of species at the minimum number of sites. Redundant regions have been eliminated, areas which do not harbour species that can be seen elsewhere. Contains a wealth of logistical information which is required to bird these sites, with accommodations, air services, associations, boats and pelagic trips, books, car rental, and telephone hotlines. A full ABA Checklist complements the guide.
