Explore how group size affects foraging behavior in Yellow-eyed Juncos, highlighting changes in foraging time model and time budgets when increasing group size. The study considers avoidance of predation, mate location, reproduction, and time/energy budgets. Results suggest that individual scans decrease while collective vigilance and interference among individuals increase with group size, influencing net foraging time. Findings are based on behavioral ecology research conducted by Baird & Dill (1996) and published in Behavioral Ecology.
