Predator vigilance and group size in mammals and birds: a critical review of the empirical evidence

MA Elgar - Biological Reviews, 1989 - Wiley Online Library
One commonly cited benefit to animals that forage in groups is an increase in the probability
of detecting a predator, and a decrease in the time spent in predator detection. A …

Why individual vigilance declines as group size increases

G Roberts - Animal behaviour, 1996 - Elsevier
A reduction in individual vigilance with an increase in group size is one of the most

Back to the basics of anti-predatory vigilance: the group-size effect

SL Lima - Animal Behaviour, 1995 - Elsevier
A negative relationship between group size and levels of individual vigilance is widespread
