Abstract

With data collected over a 1-year period, we detail the spatio-temporal structure of a flock of crows displaying distinct social categories. Presence of carrion and hooded crows was affected by the environmental factors that modulate the party size component of fission–fusion dynamics and thereby influence social complexity.
