...Much of the conventional patch selection literature ignores the possibility that animals may also benefit from the co-occurrence of conspecifics (Brown & Orians 1970; Underwood 1982; Krause & Ruxton 2002; Nilsson et al. 2007; Campomizzi et al. 2008)....

...Vigilance can influence food intake directly and hence energy gain too, as shown for free ranging large herbivores (Underwood 1982; Fortin, Boyce, Merrill & Fryxell 2004; Illius & Fitzgibbon 1994) and postulated for rabbits (Iason et al....

...Prey animals detect predators and avoid predation through increased vigilance (Underwood, 1982), but vigilance can be costly (Illius and Fitzgibbon, 1994)....

...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....
