Chapter 11.4 - Recognition of individuals within the social group: signature vocalizations

摘要: Abstract Signature vocalizations contain sufficiently unique spectral and/or temporal identity to allow conspecifics differentiate between individuals. Experimental assessment of signature content relies on: (1) accurate discrimination according individual callers using human observers and statistical methods; (2) playback experiments with in captivity or the wild. are often acquired through social vocal learning. Functions for such signals include recognition (e.g., parents offspring, mating pairs, territorial rivals) mediation interactions. cues likely be subtle, their analysis is benefit from use new data collection technologies speech techniques.
