Акустическая структура и индивидуальность контактных звуков самок и новорожденных детенышей джейрана
Oral (open-mouth) contact calls are strongly individualistic in neonate goitred gazelles (Gazella subgutturosa), but territorial mothers seem do not distinguish voices of their neonate from the alien young and approach to calls of any young and even on human imitations of neonate voices. Vocal individuality was not studied so far in voices of adult females. This study revealed that in neonate and adult female goitred gazelles, the nasal and oral contact calls differed in the acoustics and that the nasal contact calls were equally strongly individualistic in both neonates and adult females. We discuss, that, although the vocal identity of the hider neonates seems to be unimportant for individual recognition by their mothers, the individualistic voices of both mother and young might become functional further, when the young start following their mothers at 4-6 weeks of age.
