... in wing kinematics and aerodynamics across flight speeds are gradual. Take-off flight performance scales with body size, but fully revealing the mechanisms responsible for this pattern awaits new study. Intermittent flight appears to reduce the power cost for flight, as some species flap–glide at slow...

...Bret W. Tobalske; Lisa A. Puccinelli; David C. Sheridan SUMMARY We studied flying zebra finch ( Taeniopygia guttata , N=12 ), to provide a new test of a long-standing `fixed-gear'hypothesis that flap-bounding birds use only intermittent non-flapping phases,instead of variation in muscle activity...
