Abstract | Phenotypic differentiation is common among populations that have large geographic distributions. One proposed mechanism driving phenotype divergence is sexual selection, which predicts that trait differences among closely related populations are underlain by variation in reproductive performance. Here, we examined a population of Asian Barn Swallows (Hirundo rustica gutturalis) in northeastern China. We ask whether traits shown to be under divergent sexual selection in other Barn Swallow populations are under sexual selection in this north Asian population by determining whether two features of phenotype variation, tail streamer length and ventral plumage colouration (including both throat and belly regions), are sexually dimorphic, associated with patterns of assortative mating and predictive of reproductive success. In this population, the length of tail streamers did not correlate with ventral plumage colouration in either males or females. The length of tail streamers was sexually dimorphic, but we did not find assortative mating by tail streamer length. By contrast, we found no sexual dichromatism but we did find assortative mating by throat colouration. Our correlational results indicated that the breeding performance of male Barn Swallows was associated with differences in their ventral plumage colouration, suggesting that ventral plumage colouration is likely a target of sexual selection in this population. Our finding that tail streamer length is unlikely to be under sexual selection is consistent with studies of other H. rustica gutturalis populations. The result that ventral plumage colour is likely to be under sexual selection is partially consistent with previous studies on Japanese H. rustica gutturalis, in which male throat but not belly plumage colour is the sexually selected trait. |
