One of the mysteries of the English language finally explained.
One complete set of motions of a wing in flying.
- ‘Wingbeat frequency was determined by counting wingbeats from the mid point of the downstroke when the wingtip passed below the beak.’
- ‘I won't soon forget the crisp sound of snapping wood in the clear desert air that morning, or the slow powerful wingbeats of the osprey as it made its flight toward home.’
- ‘To hear them, one must be calm and pay close attention, for their wingbeats are barely audible.’
- ‘When they do take to the air, their size (wingspread is about five feet), their deep wingbeats, and the black patches on their wings and neck make them easy to recognize.’
- ‘Their wingbeats were deep and regular, and the huge flock wheeled and wandered, apparently without a clear direction.’
- ‘They are an impressive sight when flying, with slow, almost casual wingbeats and a nasal, almost yelping call.’
- ‘Aerodynamic loads affect the wing throughout the wingbeat cycle, but their influence is most obvious during downstroke.’
- ‘During the landing phase, pauses and wingbeat frequency increased and wingbeats became shallow.’
- ‘Echolocation is correlated with wing movements, and if the animal omits wingbeats it reduces the effectiveness with which it can sense its environment.’
- ‘Studies of birds and bats have homologized the two major phases of the wingbeat and stride cycles.’
- ‘Because the wingbeat frequency and power output of small ectotherms, like Drosophila, declines with decreasing temperature, the total lift generated by flies exposed to cold temperatures declines substantially.’
- ‘Hummingbirds can achieve a forward speed of 45 km per hour and their wingbeat ranges from 70 to 80 beats per second in smaller birds to 10 to 15 beats per second in giant hummingbirds.’
- ‘Their rapid wingbeats also produce a buzzing sound.’
- ‘The males circle with the slowest of wingbeats, following endlessly an identical flight path.’
- ‘Rayner et al. suggested that in both bats and birds flying in air, wingbeat gaits (the cyclic pattern of wing movements) are in fact defined by upstroke function, which varies with wing morphology.’
- ‘The bird rises almost perpendicularly in the air with fluttering wingbeats before turning rapidly and making a slow spiral descent with wings and tail outspread.’
- ‘It was previously believed that because hummingbirds with shorter wings generally have higher wingbeat frequency, they will be more maneuverable in competitive interactions.’
- ‘Both merlins repeatedly hurtled past with rapid wingbeats.’
- ‘By the scores, they lift off on laboring wingbeats and turn toward land, soaring like slender sailplanes over the rugged basaltic cliffline, then banking low to swell the ranks of those already on the ground.’
- ‘At its simplest, the flight stroke can be considered the gross up-and-down motion that makes a wingbeat.’
