Terrestrial locomotion in penguins: it costs more to waddle

Author: Pinshow, B.; Fedak, M.A.; Schmidt-Nielsen, K.

Description: The energetic cost for walking is relatively higher for penguins than for other birds or for quadrupeds of similar body mass. The morphology of penguins seems to represent a compromise between aquatic and terrestrial locomotion wherein both energy economy and speed suffer when the birds move on land.
