ocr: CONTACT CALLS Contact calls carry one of the simplest and most important messages used by birds. Roughly translated, they mean "Iam here where are yous" Young birds use contact calls to tell their parents where they are and to beg for food. Adult birds call to keepin touch with their partners, or to stay together when moving as a group. Recognition of individual calls is especially valuable to species that breed in crowded conditions.
