Evidence for energy savings from aerial running in the svalbard rock ptarmigan (lagopus muta hyperborea)
Svalbard rock ptarmigans were walked and run upon a treadmill and their energy expenditure measured using respirometry. The ptarmigan used three different gaits: a walking gait at slow speeds (less than or equal to 0.75 ms21), grounded running at intermediate speeds (0.75 ms21, U, 1.67 ms21) and aer...
