Abstract:
Studies of colour-banded zebra finches have provided mixed support for the hypothesis that females paired with attractive males will produce more sons. Variation in female mate preferences could help to explain the conflicting patterns seen in previous studies. In our experiment, females varied in their preferences for males’ colour-bands. Females mated to males of their preference produced male-biased brood sex ratios at fledging, while the specific colour of male colour-bands did not affect offspring sex.
