Abstract: Hummingbirds have received considerable attention in studies of feeding and energy regulation because of their small size, frequent feeding, and their use of energy-rich sugar solutions (e.g.Diamond et al. 1986, Ewald and Carpenter 1978, Hainsworth 1981).They store nectar in a crop, and this internal reservoir supplies energy between foraging bouts (Hainsworth and Wolf 1972, Karasov et al. 1986).The rate of crop emptying, therefore, should influence foraging frequency (Karasov et al. 1986, Wolf and Hainsworth 1977).Because the crop is a major interface between feeding input of energy and outflow for energy use, there has been interest in the determinants of cropemptying rates (DeBenedictis et al. 1978, Hainsworth
