bats and birds represent the outcome of selection for energy
efficiency during migratory flight ..." rather than going back to some
seminal references - such as Keast's 1968 paper.
No but ... when you look at the method used for attaching the
transmitters (including anaesthetising the birds and holding them
overnight, during which they lost weight), and the admitted low power
of their statistical analyses, I'd be a bit worried about the
robustness of the results! ... interesting as they might be.
