Hierarchical group dynamics in pigeon flocks

The results suggest that hierarchical organization of group flight may be more efficient than an egalitarian one, at least for those flock sizes that permit regular pairwise interactions among group members, during which leader–follower relationships are consistently manifested.

Heterogeneous structure in mixed-species corvid flocks in flight

Tree structures are employed by pigeons as leadership structures to flock

Collective behaviors displaying a variety of fascinating movement patterns are thought to be products of complex interplay among individuals. Previous studies have proposed the hierarchical

Some Causes of the Variable Shape of Flocks of Birds

It is hypothesised that variability of shape increases when there are larger local differences in movement behaviour in the flock, and this is investigated with the help of a model of the self-organisation of travelling groups, called StarDisplay, since such a model has increased the understanding of what causes the oblong shape of schools of fish.

Reciprocal relationships in collective flights of homing pigeons.

It is shown that both reciprocal relationships and a stratified hierarchical leadership are important and necessary in the collective movements of pigeon flocks and an integrated combination of both compromise and leadership which drives the group's movement decisions.

Application of robo-pigeon in ethological studies of bird flocks.

It is suggested that direct manipulation of flight trajectories by a robo-pigeon might be a useful causal tool to study the collective behavior of bird flocks.

A novel control mechanism for natural flocks

This book presents a meta-ethnography of the determinants of infectious disease in eight operation theatres around the world over a 25-year period: the immune systems of eight operation rooms and their consequences.

The Role of the Dynamics of Relative Motion in Information Passing in Natural and Engineered Collective Motion

This dissertation presents the design of a testbed in which robotic fish interact with a school of live fish in real time and derives control laws, based on killifish-like coordinated speed oscillations into a rich family of moving formations along circular trajectories.

Incidental sounds of locomotion in animal cognition

An alternative, or complimentary, hypothesis is presented that synchronization of group movements may improve hearing perception and reduce auditory masking through periods of relative silence and facilitate auditory grouping processes.

Networks of Influence

These constructs enable scientists to nuance the collective behavior observed in the social structure created by each species from the school of fish to the murmuration of swallows.

Notes on the Flocking of Shore Birds

The bunching and wheeling is most frequent when a flock takes wing and may well serve to hold it together until the faster and slower individuals have adjusted speeds.

Induced Drag of a Bird Flock

It is suggested that improved flight efficiency is not an important reason for migration in large, three-dimensional flocks, so the simplest aerodynamic theory has been used to estimate the change in total induced drag.

The chorus-line hypothesis of manoeuvre coordination in avian flocks

It is shown by analysis of film of dunlin (Calidris alpina) flocks that a single bird may initiate a manoeuvre which spreads through the flock in a wave, which reaches mean speeds three times higher than would be possible if birds were simply reacting to their immediate neighbours.

Three-Dimensional Analysis of Turning Within Airborne Bird Flocks

The repositioning of birds within the overall structure of turning and wheeling flocks indicates that adaptive strategies for predator avoidance could be based on a bird's ability to easily reposition within a flock, rather than on the distinctly different advantages of maintaining a peripheral or central location within the flock.

Formation Flight in the Canada Goose (Branta. C. canadensis)

The function of formation flight in Canada Geese and other large waterfowl is unknown, although two hypotheses have be en proposed. One hypothesis suggests that formation types are a function of

V-like Formations in Flocks of Artificial Birds

A small set of fully distributed positioning rules are introduced to guide the birds' movements and demonstrate, by means of simulations, that they tend to lead to stabilization into several of the well-known V-like formations that have been observed in nature.

A Flapping Wing Model for Avian Formation Flight

There has been much speculation about the significance of avian formation flight, yet it's purpose is still unknown. To explain the phenomenon, two hypotheses have been proposed. The first describes

It is argued that the key to understanding collective behaviour lies in identifying the principles of the behavioural algorithms followed by individual animals and of how information flows between the animals.
