Nestling sex ratios in a population of Bluethroats Luscinia svecicainferred from AFLP

Bluethroat (Luscinia svecica) Science Article 21


We studied the sex ratio of Bluethroat Luscinia svecica broods using AFLPs. Our aim was to test whether there is a bias towards males that could be explained by sexual selection theories, or conversely, a bias towards females that could help explain the female-biased sex ratio among juveniles observed at a wintering site.
