Abstract
A cost-benefit model predicting threshold requirements for establishment of feeding territories in nectarivorous birds was tested by comparing 24-hour energy production of nectar with energy budgets in territorial and nonterritorial Hawaiian honeycreepers. The test was positive and demonstrated that nectar productivity was more important in determining establishment of territories than intrusion pressure and floral dispersion.
