  Food transfer in common marmosets: parents change their tolerance depending on the age of offspring
■ 概要
  In this study, we investigated whether adult common marmosets (Callithrix jacchus) change their tolerance to offspring begging for food depending on the offspring's age.To directly compare the responses of a parent with its older and younger offspring, we placed one parent and one offspring in a testing space at one time. Parents refused older offspring more frequently than younger offspring and transferred food more often to younger offspring than to older offspring.
