MANY ornithologists who spend much of their time abroad have access to little literature and may not know how to use their opportunities fully nor how, where or whether to publish knowledge they acquire. The purpose of this handbook is to meet this situation and' to encourage the study of birds by pointing out where worthwhile opportunities exist. The bulk of the book consists of 54 short articles, averaging 4 pages each, written by a panel of 44 experts, mainly British but including workers in Africa, Australia and America. The range of subjects is remarkably wide: classification, plumage, field-identification, parasites and collecting of all s o r t s ; geographical aspects including range, migration, navigation, birds at sea, in the Tropics, in the Arctic, e t c . ; general behaviour (learning, food, predation, calls, roosting, associations, etc.), 5 articles on aspects of breeding, 4 on conservation, and 20 on study techniques including photography, automatic recorders, ringing, censuses, aviculture. Finally there are suggestions for special study, and regional information for the whole world excluding Europe, U . S . S . R . and North America.
