Mate choice is not important for female reproductive success in the common Rosefinch (Carpodacus erythrinus)

Rosefinch (Carpodacus erythrinus) Science Article 1


I studied mate choice in relation to female reproductive success in the Common Rosefinch( Carpodacuesr ythrinuso) over a four-year period. Approximately 50-99% of the variance in female reproductive success was due to nest predation during incubation. Because males did not defend nest sites and females probably face time constraints, I conclude that they paired unselectively. This is supported by the lack of correlation between male phenotypic characteristics and pairing success and the random pattern in male pairing order
