The evolution of acoustic identity signals in birds

Reers, Hendrik (2011): The evolution of acoustic identity signals in birds. Dissertation, LMU München: Fakultät für Biologie

Abstract

In this dissertation I present several novel findings on the evolution of acoustic identity traits in birds, with a special focus on parent-offspring communication. I present novel insights on how vocalizations are influenced by condition, environment and genes, and which acoustic parameters are used to form unique identity signatures. Furthermore, I provide first experimental evidence for the role of acoustic similarity for recognition errors in birds, supporting the importance of negative-frequency dependent selection for the evolution and spread of individual signatures.
