The confusion effect describes the phenomenon of decreasing predator attack success with increasing prey group size. These beautiful starlings were filmed in Israel as tens of thousands of starlings fly in a massive murmuration in the skies above Rahat. The mechanism underlying this collective behavior remains debated. The starlings are generally a highly social family.

Temperature was negatively correlated with duration but the effect was much weaker than that of day length. A higher frequency of attack during a hunting sequence resulted in a higher frequency of collective escape events. Under light irradiation, due to the dominant nonelectrolyte diffusiophoretic interaction resulting from the overlap of asymmetric nonelectrolyte clouds around adjacent individuals, these flocks exhibit intriguing collective behaviors, such as dilatational negative phototaxis, high collective velocity, and adaptive group reconfiguration. For this classification, we, only included attacks that occurred primarily in the two-, dimensional plane (vertically or horizontally).

Specifically, we examined: the percentage of individuals in a group that startled, the resulting group area, and the longevity of the flash expansion. A wave event was most likely when the raptor attacks at medium (rather than high or low) speed. bours in flock s of starlings: relating a mode l to empirical data. Huge starling flocks used to gather over Manchester, Leeds, Newcastle, Liverpool, Edinburgh, Glasgow and Belfast, but today you have a much better chance of seeing the birds in rural areas. sured the duration and frequency of wave events, black-, ening and cordons and the frequency of split and merge, number of pulses within a wave event as well as the rel-, ative location and speed of attacks taken by two observers, (CC and RFS) agreed with one another. The collective noun for starlings is the word you would use to describe a group of starlings. Survival rates of scaled quail during the breeding season were higher than those reported for radiotagged northern bobwhite in west Texas at similar latitudes. The scale of agents ranges from nanomotors and microswimmers, to cells, fish, birds, and people. We monitored 72 active flycatcher nests using camera systems from 1998 to 2000. In fish schools, blackening was shown to result from, Combining models and empirical data, wave events are likely, caused by individuals making zig manoeuvres of rolling side-, ward and back that increase their wing area visible to observers, ies of fish schools have shown that simple avoidance behaviour, of fleeing ahead of the predator can lead to a variety of escape, responses such as flash expansions, vacuoles, fountain events, patterns of collective escape. Specific alternatives that are currently the focus of attention are: enforcement and support for a move to less intensive management; intra-guild predation by golden eagles; diversionary feeding; and a harrier brood management scheme. As part of a larger study on scaled quail ecology and management, and in an attempt to determine whether breeding season sur- vival could be implicated in this decline, we monitored survival of, 1.
