Analysing the distribution of those 195 bird species that are restricted to the humid trans-Andean lowlands, we distinguish on the basis of their geographic distribution several distinct groups (Fig. 14 and Table 2; the species of Groups A, B, C, D, and E are listed and discussed on p. 51 ff.): A. Species of Caribbean northern Middle America: 7 species (Fig. 15). B. Species of Caribbean southern Middle America: 14 species (Fig. 15). C. Species of Pacific
