..., wingbeat frequency, and flight and resting metabolic rates of workers could predict the trait values of queens that were more than fourfold larger. Flight success of queens decreased over time in part because of a large increase in body mass and a decrease in traits linked with flight, namely wingbeat...

..., their median peak-to-peak dorsal body (DB) acceleration and median DB amplitude also increased. This, in turn, led to higher airspeeds, suggesting that birds fly slower when traversing unfamiliar terrain. By contrast, after route efficiency stabilised, birds exhibited increasing wingbeat frequencies, which did...

...Douglas L. Altshuler; Kenneth C. Welch, Jr; Brian H. Cho; Danny B. Welch; Amy F. Lin; William B. Dickson; Michael H. Dickinson SUMMARY Hummingbirds can maintain the highest wingbeat frequencies of any flying vertebrate – a feat accomplished by the large pectoral muscles that power the wing strokes...

... to 1065 mg, was found to strongly affect hovering flight mass-specific metabolic rates, which ranged from 114 ml CO 2 h -1 g -1 in small species to 37 ml CO 2 h -1 g -1 in large species. Similar variation of wingbeat frequency in hovering flight occurred among small to large species, and ranged from 250...

For periods of voluntary, uninterrupted, self-sustaining flight, metabolic rate was independent of air temperature between 19 and 37°C. Thorax temperatures( T th ) were very stable...

Under these normodense but hypoxic conditions, hummingbirds did not alter stroke amplitude but instead reduced wingbeat frequency until...
