Extrapair paternity in chestnut-sided warblers is correlated with consistent vocal performance

Byers, Bruce E. - In: Behavioral Ecology 18 (2007) 1, pp. 130-136

The elaborateness of many bird songs is commonly presumed to have evolved under the influence of sexual selection by female mate choice. Thus, aspects of acoustic diversity, such as song repertoire size, are seen as likely targets of female choice. In many songbird species with song repertoires,...

Mate guarding, male attractiveness, and paternity under social monogamy

Kokko, Hanna; Morrell, Lesley J. - In: Behavioral Ecology 16 (2005) 4, pp. 724-731

Socially monogamous species vary widely in the frequency of extrapair offspring, but this is usually discussed assuming that females are free to express mate choice. Using game-theory modeling, we investigate the evolution of male mate guarding, and the relationship between paternity and...
