Abstract
To examine the performance compromises necessitated by adaptations for high efficiency in flight, such as highaspect ratio wings, the flight morphology and acceleration performance of a guild of coursing aerial insectivores (swifts andswallows) were compared with those of a guild of avian generalists. Though phylogenetic non-independence made inference ofadaptation difficult, biologically significant differences in aspect ratio and acceleration performance probably exist between thetwo groups of birds. A model of aerial insectivory is presented to illustrate the performance demands of this foraging methodand the impacts of the compromises between high efficiency in sustained flight and turning- and linear-maneuveringperformance.
