Onshore energetics in penguins: Theory, estimation and ecological implications.
International audience Penguins are known to have high pedestrian locomotory costs in comparison to other cursorial birds, but the ecological consequences of this difference have received limited attention. Here we present a method for the accurate estimation of onshore energetics based on measureme...
