...3) probably spend less time foraging as reported in low ranked peripheral distributed bison (Bos bison) (Berger and Cunningham 1988) and among several African ungulates (Underwood 1982)....

...Mesoherbivores in particular, which are most susceptible to predation, should benefit from increased detectability, enabling them to spend more time foraging and less on predator-avoidance behaviour (Riginos, 2015; Sinclair et al., 2003; Underwood, 1982)....

...…2), despite less browse availability, suggesting instead that anti-predator benefits make grazing lawns highly attractive to mesoherbivores because of their higher susceptibility to predation (Augustine, 2004; Burkepile et al., 2013; Sensenig et al., 2010; Sinclair et al., 2003; Underwood, 1982)....

...Such habitat differences may have influenced the evolution of social and anti-predator behaviour in antelope (GEIST, 1974; JARMAN, 1974; ESTES, 1974) and may also affect both predator and prey behaviour on a day to day basis (SCHALLER, 1972; KRUUK, 1972; CURIO, 1976; EDMUNDS, 1974)....

...If scanning reduces predation, it may take up less of the large animals' time either because both the number and the range of potential predators are smaller (JARMAN, 1974; GEIST, 1974), or because these antelope, being found in large groups, either are (a) less easy for a predator to find, (b) share vigilance with other group members (CARACAO et al....

...The smaller and, according to JARMAN (1974), the more selective species are those which show significant correlations between the rate of looking and indices of feeding success, supporting the possibility that scanning forms a part of foraging behaviour....
