Abstract
This paper considers interactions between time budgets, group size and overwinter survivorship for members of avian foraging flocks. Individuals should respond to the social environment and energetic requirements by varying their allocation of time to predator detection, feeding and aggression. Predictions relate time budgets qualitatively to both the expectation and variance of foraging group sizes. Optimal group sizes for dominants and subordinates are compared to the expected group size.This publication has 2 references indexed in Scilit:
