ResumoTHIS is the first in a series of papers on the behavior of tropical finches, tanagers, and honeycreepers. All or most of these birds are usually considered to be closely related to one another, and to the vireos, warblers, and icterids (see, for instance, Mayr and Amadon, 1951; Beecher, 1953; Tordoff, 1954; Stallcup, 1954; and Wetmore, 1960). The group as a whole will be called American nine-primaried songbirds throughout this and the following papers of this series. Most of the behavior patterns discussed in these papers are ritualized patterns, or i.e., patterns that seem to have become specialized, in form and/or frequency, to subserve signal functions. The principal objective of these papers is to present the material for a subsequent analysis of the evolution of display patterns. Special attention will be paid to those displays, and aspects of displays, that seem to be most significant from a comparative point of view. The treatment of different species and groups of species will be very unequal in the following papers, as some species were observed at much greater length than others. The species will also be discussed in a somewhat arbitrary sequence, as some of them are still being studied at the present time.
