Bottom line: According to Wayne Potts, a zoologist who published in the journal Nature in 1984, birds in flocks are able to change direction quickly not just because they are following a leader, or their neighbors, but because they see a movement far down the line and anticipate what to do next. Red-winged blackbirds at sunset via Wikipedia. How do birds in flocks change direction so quickly? Flock of birds that fly in V formations may be doing so to conserve energy. Flocking can increase the possibility of finding food and protecting each other from trouble and predators. Experts believe flocks increase the odds of survival and safety. Pelicans, geese, and other waterfowl form lines and Vs,… Why do birds fly in V formations?īirds form clusters of organized groups, called flight flocks, for a reason. But only a relative handful really fly together, creating what University of Rhode Island biologist Frank Heppner, in the 1970s, proposed calling “flight flocks”: namely, highly organized lines or clusters.

This is a very general model, which can be applied to similar situations." "We propose a simple model for a system whose members have the tendency to follow the others both in space and in their state of mind concerning a decision about stopping an activity. Stopping or starting of a collective behavioural pattern in a group of people or animals. This can be compared to an avalanche of piled up sand, which would occur even for perfectly symmetric and cautiously placed grains, but in reality happens much sooner because of increasing, non-linear fluctuations.Īs the researchers explain, "Our main motivation was to better understand something which is puzzling and out there in nature, especially in cases involving the In the absence of a decision making leader, the collective shift to land is heavily influenced by perturbations the individual birds are subject to, such as the birds' flying position within the flock. Using a simple self-propelled particle (SPP) system, which sees the birds represented by particles with such parameters as position and velocity, the researchers from Budapest, Hungary, find that the collective switching from the flying to the landing state overrides the individual landing intentions of each bird. New research published today, Wednesday 15 September, in New Journal of Physics, uses a particle model to explain the collective decision making process of flocks of birds landing on foraging flights.
