A Spectrum of Nectar-Eater Communities

Abstract
Three nectar-eater systems differ in the degree and consistency with which nectar is limiting to the birds. A gradient of nectar limitation exists, ranging from no limitation to limitation some years but not others, to apparent limitation most of the time. The ecological and evolutionary effects of different limitation regimes on aggression and tcrritoriality, on resource partitioning and avian community structure, and on plant pollination strategies are discussed.
