flock of starlings

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 corresponding structural complexity concerns rapid variation in density and shape of the flock over time. ... An example regarding complexity is that of ant colonies in which more complex societies are characterized by lower individual complexity (Anderson and McShea 2001). The response seems adaptive because of lowered danger at a larger distance to the location of attack. Content courtesy of Springer Nature, terms of use apply. Other models were used to test the effects of, attack strategy, including explanatory variables such as, attack speed and location, and roosting site on the proba-, bility of each of the specific collective responses occur-, ring within or after 5 s of an attack. This has stimulated the new field of active matter in recent years, which focuses on the physical aspects of propulsion mechanisms, and on motility-induced emergent collective behavior of a larger number of identical agents. occurred in response to an attack and was followed by splits. Such behavior, however, was not the rule. Likewise, attraction to conspecifics is thought to provide benefits through, for example, selfish herding. We may also use these personal data internally within, ResearchGate and Springer Nature and as agreed share it, in an anonymised way, for purposes of tracking, analysis and reporting. These include, but are not limited to: group size, polarization, speed, turning speed, speed or directional correlations, and distances to near neighbours. If starlings roost in trees: In fall and winter, the communal night roosts of thousands of starlings create accumulations of droppings below the roost. Here we investigate whether, when, and why stooping promotes catch success, using a three-dimensional, agent-based modeling approach to simulate attacks of, Scaled quail (Callipepla squamata) populations declined markedly across much of their range from 1988-2004, however little research has been conducted to investigate possible causes for the decline. Together, in flight, in mesmerizing flocks that sometimes number in the hundreds of thousands, they are a breath-stealing wonder, a pulsating, swooping, living, harmonized whole, seemingly defying the laws of nature while defining nature itself. Collectively, though, starlings transform into something else entirely. Our findings suggest that starling murmurations are primarily an anti-predator adaptation rather than being undertaken to attract larger numbers of individuals to increase roost warmth. Very little is known about this phenomenon, called flash expansion, such as whether it is triggered by one individual or a threshold and how information is transferred between group members. We performed a controlled experiment with whirligig beetles in which the ratio of sighted to unsighted individuals was systematically varied and emergent flash expansion was measured. The results were presented on Tuesday September... On 31 August, Louise Vet (director of the Netherlands Institute for Ecology, NIOO-KNAW), Ben Feringa (University of Groningen, Nobel Prize winner for Chemistry 2016) and Rens Waters (general and scientific director of the Netherlands Space Research Institute SRON) opened the Origins Center, in...

Our experiment is the first investigation of the effects of flock size and density on the ability of a (human) predator to track and capture a target starling in a realistically simulated three-dimensional flock of starlings. 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.

Inspired by astonishing collective motions and tactic behaviors in nature, here we show phototactic flocking of synthetic photochemical micromotors. However, there is a paucity of research into the influence of this effect in coherent groups, such as flocks of European starlings (Sturnus vulgaris).

Recently these patterns have been characterised, quantified, and classified, in relation to the hunting behaviour of the predator at different degrees of predation risk. For instance, 25% of all attacks were followed by a flash, cordon and vacuole in order of decreasing frequency. When enriched with hydroxyl groups, TiO2 micromotors can spontaneously gather into flocks in aqueous media through electrolyte diffusiophoresis. Such machines provide the basis for multifunctional, highly responsive, intelligent (artificial) active materials, which exhibit emergent behavior and the ability to perform tasks in response to external stimuli. The ubiquity of consistent inter-individual differ- ences in behavior (‘‘animal personalities’’) [1, 2] sug- gests that they might play a fundamental role in driving the movements and functioning of animal groups [3, 4], including their collective decision-mak- ing, foraging performance, and predator avoidance.
