Sustained vigilance and animal performance
Article Abstract:
A set of models are presented to examine the effect of sustained animal vigilance and performance in relation to foraging activity. The allocation of time between foraging activity and rest and the length of each foraging episode were considered. The results revealed longer foraging time and rest for demanding foraging activities and increased as the tasks become more difficult. This suggests that vigilance is a factor that determines temporal patterns of animal behavior.

Vigilance by female Dall's sheep: interactions between predation risk factors
Article Abstract:
The effects of predation risk factors on vigilance was analyzed in adult female Dall's sheep that were engaged in foraging bouts. Increased group size reduced the levels of vigilance among adult female Dall's sheep during foraging bouts. However, the relationship between levels of vigilance and group size decreased as the sheep foraged near cliffs. Furthermore, the sheep became more vigilant when they moved farther from the cliffs.

Alarm calls as costly signals of antipredator vigilance: the watchful babbler game
Article Abstract:
Research describing alarm calling behavior is presented. A game-theoretical model is developed to investigate the proposition that some alarm calls are signals to the predator that it has been detected.
