| Outline of Final Research Achievements |
To understand the collective behavior of flock of birds in physical view points based on quantitative measurement of individual motion of members, we have developed a portable stereo imaging system made of carbon material with baseline of 2 meters as well as image processing software and we conducted field measurements of the trajectories of individuals in the skeins of wild geese. Using a stereo camera system, we estimated the detailed adjustment processes between neighbors to estimate effective interactions. Based on the field measurements, we proposed a phenomenological equation of motion for collective flight of geese and discussed the conditions for stability of collective flight.
