Balance: a neglected factor when attaching external devices to penguins
We observed that external attachments on penguins reduced their balance, which may be of as great concern to the individuals as the effect of increased drag. Little penguin Eudyptula minor swimming activity was observed in captivity at the Penguin Parade (r), Phillip Island, Australia. Initially, ti...
