Abstract
We studied adaptations of digestive physiology that permit Rufous (Selasphorus rufus) and Anna's hummingbirds (Calypte anna) to absorb sugar-water meals rapidly and efficiently. As measured with soluble markers, transit times ( omnivore > carnivore.This publication has 14 references indexed in Scilit:
