What is the magnitude of the group-size effect on vigilance? (2008, background): “Time spent vigilant decreased to a larger extent in circular or square feeders than in narrow feeders (Bekoff 1995; Sadedin and Elgar 1998).”
Vigilance behaviour of polar bears (Ursus maritimus) in the context of wildlife-viewing activities at Churchill, Manitoba, Canada (2004, background): “Several studies documented that individual vigilance decreases with increasing group size (Quenette, 1990; Kildaw, 1995; Roberts, 1996; but see Bekoff, 1995), and that differences between sex (Quenette, 1990; Burger and Gochfeld, 1994; but see Elgar, 1989), season, and habitat exist (Quenette,…”
Isolation from mammalian predators differentially affects two congeners (2002, background): “Patterns of time allocation can provide an indication of how animals perceive predation risk (Bekoff, 1995).”
Increasing the costs of conspecific scanning in socially foraging starlings affects vigilance and foraging behaviour (2005, background): “…in linear (versus circular) arrays spend more time scanning, change head and body positions more often, and show less coordination in head movements, suggesting that individuals attempt to monitor conspecific behaviour in conditions where that information is difficult to obtain (Bekoff 1995).”
Aerial flocking patterns of wintering starlings, Sturnus vulgaris, under different predation risk (2009, unknown): “The idea that individuals use the behaviour of flockmates as a source of information about predation risk is well documented (e.g. Elgar 1989; Bekoff 1995); however, individual birds in a flock could use the behaviour of other flocks as well, since their three-dimensional range of interaction possib”
Flock density, social foraging, and scanning: an experiment with starlings (2004, unknown): “Different types of information can be gathered through visual scanning (Bekoff, 1995, 1996; Catterall et al., 1992; Valone and Wheelbarger, 1998).”
