Vigilance as a benefit of intermittent locomotion in small mammals
Article Abstract:
The hypothesis that pauses in locomotion serve to improve vigilance against predators in grey squirrels and chipmunks was tested by videotaping several animals in motion. Both species spent more time pausing when moving away from forest cover than when travelling back towards forest cover. Chipmunks paused more than the squirrels when approaching patches. These results suggested that pausing in squirrels improves anti-predator vigilance. However, insufficient evidence was found to match the predictions in the hypothesis for chipmunks.

Head raising during foraging and pausing during intermittent locomotion as components of antipredator vigilance in chipmunks
Article Abstract:
The relation between patterns of intermittent locomotion and patterns of vigilance in foraging chipmunks is examined. The conclusion states that pauses in locomotion are very similar to head raising and should be taken into account in vigilance studies.
