Abstract  Vigilance in vertebrates is often inversely related to group size. We present evidence that distance to bushes and location within the herd are also critical factors in vigilance in springbok (Antidorcas marsupialis) in Etosha National Park, Namibia, where they are the preferred prey of cheetahs (Acinonyx jubatus). Most springbok feed in heterospecific herds, both by grazing on grass and browsing on bushes. We studied 1245 animals; variations in vigilance (time alert) were explained… Expand

Vigilance in Przewalski's gazelle: effects of sex, predation risk and group size
TLDR
The results suggest that mothers are more vigilant suggesting greater vulnerability and that males may have increased their vigilance to compete for higher social ranks, but failed to find an interaction between group size and predation risk on vigilance. Expand
Group size effects on foraging and vigilance in migratory Tibetan antelope
TLDR
It is suggested that the results of investigated group size effects on vigilance and foraging behaviour during the migratory period in female Tibetan antelope are best explained by competition for food and risk of predation. Expand
Vigilance and its complex synchrony in the red-necked pademelon, Thylogale thetis
TLDR
Some vigilance benefits may be obtained from the presence of conspecifics even in species that aggregate only temporarily on food patches without forming more permanent social groups, as in red-necked pademelons foraging at night in nonpersistent aggregations in a clearing in rain forest. Expand
Vigilance in a solitary marsupial, the common wombat (Vombatus ursinus)
TLDR
The results support the assumption that individuals scan independently of each other in this solitary species of wombats, which tolerates the presence of conspecifics within their home range. Expand
Hunting increases vigilance levels in roe deer and modifies feeding site selection
TLDR
The results indicate that roe deer trade off risk avoidance for food availability in hunted populations, suggesting a higher level of costly exclusive vigilance during the hunting season. Expand
An adaptive system of vigilance in spotted deer (Axis axis) herds in response to predation
TLDR
It is surmised that this three-phase vigilance system, probably operative in the chital herd, allows for adaptation to predation risk and has possibly co-evolved with the optimal hunting strategy of the predator. Expand
The impact of herd composition and foraging area on livestock predation by big cats in the Pantanal of Brazil
TLDR
Increasedwater levels caused the herd to concentrate on higher ground usually near forested areas, suggesting an increase in cattle vulnerability to predation, and a greater proportion of adults in the herd may also increase the possibility for defensive behavior, likely resulting in greater protection of younger cattle.

Low Foraging Success of Semipalmated Sandpipers at the Edges of Groups
Variation in foraging success in relation to spatial position in a group is little known in species that feed on mobile prey that can hide or flee upon disturbance by foragers. I examined theExpand
Red deer allocate vigilance differently in response to spatio-temporal patterns of risk from human hunters and wolves
Abstract ContextUngulate prey can use increased vigilance to reduce their risk of predation, but little is known of the combined and interactive risk effects from humans and wolves in determiningExpand
On the Relationship between Herbaceous Cover and Vigilance Activity of Degus (Octodon degus)
TLDR
The hypothesis that cover of herbaceous vegetation is mostly obstructive to degus when active above ground is supported, a finding that contrasts with previous evidence supporting that shrub cover provides refuges against predators. Expand

Vigilance Behaviour in Grazing African Antelopes
TLDR
Time spent looking varied with position within the group; this effect was strongest in closed habitats, where central animals tended to scan least and feed most, and within species, animals inclosed habitats, those with dense vegetation, tended to spend more time in looking than did animals in the open. Expand
Vigilance Behaviour in African Ungulates: The Role of Predation Pressure
TLDR
It is suggested that predation pressure is the principal influence on vigilance behaviour in ungulates and even very low risk of predation appears to contribute to vigilance. Expand
EFFECTS OF GROUP SIZE AND SEX ON VIGILANCE IN OSTRICHES (STRUTHIO CAMELUS): ANTIPREDATOR STRATEGY OR MATE COMPETITION?
TLDR
It is suggested that vigilance in females relates primarily to predation pressure, and thus decreases with group size, but in males vigilance relates to bothpredation pressure and social factors (male-male competition). Expand
PREDATOR VIGILANCE AND GROUP SIZE IN MAMMALS AND BIRDS: A CRITICAL REVIEW OF THE EMPIRICAL EVIDENCE
  • M. Elgar
  • Psychology, Medicine
  • Biological reviews of the Cambridge Philosophical Society
  • 1989
TLDR
Most of the studies fail to adequately demonstrate an unambiguous relationship between vigilance behaviour and group size, but many studies reveal interesting features of the relationship between Vigilance and Group size that should provide fruitful avenues for future research. Expand
Vigilance in African Mammals: Differences Among Mothers, Other Females, and Males
TLDR
It is suggested that in 1993 herd size was above a threshold where increases in group size can lead to further decreases in vigilance, and animals on the edge of herds devoted more time to vigilance than intermediate or central animals. Expand
Group foraging, distance to cover and vigilance in the teal, Anas crecca
TLDR
Investment in vigilance with respect both to group foraging and distance to obstructive cover was studied in the teal and group size per se did not affect the level of vigilance after controlling for the effect of neighbour distance. Expand
Predator Vigilance Costs of Allogrooming in Wild Blue Monkeys
TLDR
The data suggest that vigilance costs occur in wild blue monkeys engaged in allogrooming, and they may accrue to the recipient ofgrooming as well as the groomer, and may be compensated for both partners by long- or short-term benefits. Expand
Dangerous Lions and Nonchalant Buffalo
TLDR
It is concluded that vigilance in buffalo was not restricted to predator detection, and that in periods in which epidemics or drought conditions are absent it was normal that ultimately some 90% of the large herbivores fell victim to predation. Expand
Effect of group size on vigilance while drinking in the coati, Nasua narica in Costa Rica
TLDR
Vigilance and the duration of drinking bouts at a waterhole in Palo Verde, Costa Rica were examined in coatis to suggest that waterholes are particularly dangerous places because their location is known to predators and coati are required to come to them. Expand
Habitat, Group Size, and the Behaviour of White-Tailed Deer
TLDR
The behaviour of white-tailed deer on Ossabaw Island, Georgia was examined in three habitats which differed in cover density and forage abundance, suggesting that cover density rather than forage characteristics was related to deer group size. Expand
