Tropical plant-visiting birds and mammals feed on two distinctly different resources: nectar and fruit. This chapter describes the basic nutritional characteristics of the nectar and fruit resource bases and how the availability of these resources varies temporally and spatially. It presents quantitative estimates of the biomass of these resources within communities and the biomass of vertebrate nectarivores and frugivores that they support. It begins by summarizing data on the extent to which tropical plants rely on birds and mammals as their primary or exclusive pollinators and seed dispersers.
