How do birds that flock together in the winter forage in a group without competing with each other for food?. PROCEDUREPrevious studies suggest that when food is approximately evenly dispersed in anenvironment, solitary foraging yields a higher energy return per unit time (or less time toacquire a set amount optimal foraging predictions Kathryn M.

FORAGING. : is the act of searching for, chasing, capturing, killing and consuming food.. PHEROMONES. They are chemicals produced as messengers that affect the behavior of other individuals of insects or other animals.. They are also called ‘ectoharmones’.. The term pheromones was introduced by Karlson and Butunadt in 1959.. . . Parasitoid. An organism that lives in or on the body of its host, at least during a part of its lifecycle.

Identify the cultural characteristics of a society that might be inferred from knowing the society’s subsistence patterns. Pheromones are types of chemicals that are released by organisms as a means of communication with organisms of the same species. .
