在过去的50年里，外部连接的传输和记录设备极大地帮助阐明了自由生活动物的生物学。然而，这种装置可能会妨碍动物，使得所监测的行为不能代表未装备的同种动物。我们建议，如果动物配备了不同大小的设备，记录的参数随大小的变化可以用来外推到无障碍动物的条件。使用这种方法与阿德利企鹅Pygoscelis adeliae表明，未装备的鸟类预计范围更远，游泳更快，潜水更深，水下比装备的鸟类更有效，所获得的数据不仅为有关物种设定了基线信息，而且还使我们能够透视设备的有害影响。
Externally-attached transmission and logging devices have greatly helped elucidate the biology of free-living animals over the last 50 yr. However, such devices may hinder animals so that the behaviour monitored is not representative of unequipped conspecifics. We suggest that if animals are equipped with devices of varying size, the change in recorded parameters with size can be used to extrapolate to the condition in unencumbered animals. Use of this approach with Adelie penguins Pygoscelis adeliae showed that unequipped birds are predicted to range farther, swim faster, dive deeper and be more efficient underwater than equipped birds, The derived data not only set baseline information for the species concerned but also allow us to put the deleterious effects of the devices into perspective.
