IN THESE days of great specialization within the biological sciences, it is all too rarely that a problem in one branch arises directly out of observations in another, superficially quite unrelated one. That this does occur, is, however, significant as a reminder that all of biology is a related whole, and also as a corrective to the tendency to spin out the threads of any one specialty to the point where all relation to total biological reality becomes very tenuous. At first glance it might seem that a problem in animal behavior and a study of microbiological metabolism were mutually remote, but the facts are otherwise, as will be shown in the present paper. Furthermore, one cannot avoid a feeling that a problem growing out of the much maligned" natural history" aspect of biology may have a reality of a different sort from one emanating from the library and the armchair of the technical specialist.The honey-guides, a small family of birds related to the woodpeckers and the barbets, comprise eleven species, classified in four genera. All but two of these eleven occur only in Africa south of the Sahara, while the other two are Asiatic, one in the Himalayas and one in the forests of Malaya, Sumatra, and Borneo. Few families of birds present more puzzling problems to the student of animal behavior, inasmuch as the honey-guides are parasitic in their breeding habits, and because one section of the family has developed a most remarkable symbiotic relationship with certain mammals-ratels and human beings-a relationship that has given the birds both their common name of honey-guides and their technical one ([ndicatoridae). In effect, the birds guide or lead these associates to the near vicinity of wild bees' nests, then wait there for them to open the hives, and finally the birds feed on the bits of
