Robust autumn social attributes predict spring courtship skills in juvenile female brown-headed cowbirds, Molothrus ater
0003-3472/$38.00 The Association for the Study of A http://dx.doi.org/10.1016/j.anbehav.2013.01.009 Individuals often show predictable variation in social tendencies over time and across contexts. In species that rely on social interaction for the development of courtship behaviours, predictable variation in juvenile social behaviour may influence the ontogeny of courtship skills by exposing yo...
متن کاملDevelopmental origins of sociality in brown-headed cowbirds (Molothrus ater).
Five variables were studied relating to the emergence of sociality in hand-reared cowbirds (Molothrus ater): proximity, sex assortment, reactions to adults, head-down displays, and vocalizations. The authors were especially interested in female sociality because adult female birds influence male courtship, song content, and use through proximity, attention, and displays. The authors found that ...
متن کاملBehavioral compatibility and reproductive outcomes in two distant populations of captive brown-headed cowbirds (Molothrus ater).
Increased understanding of geographic variation in courtship behavior in animal species can provide insight into the ways behavior may influence evolutionary change. Here, the relationship of geographic variation in courtship behavior to reproductive outcomes was tested in two distant and behaviorally distinct populations of brown-headed cowbirds, Molothrus ater, by comparing rates of copulatio...
متن کاملDo juvenile males affect adult males’ reproductive success in brown-headed cowbirds (Molothrus ater)?
The present study was motivated by a recent anomalous finding between individual competitive performance and reproductive output in brown-headed cowbirds (Molothrus ater). White et al. (2002c) found that adult males who were housed with juveniles outcompeted adults who were housed with other adults when they were brought together to compete for mating opportunities. Although the males in groups...
متن کاملFemale proximity stimulates development of male competition in juvenile brown-headed cowbirds, Molothrus ater
We investigated how individual variation in social behaviour among group members interacts to affect social structure and development of reproductive skills. We randomly assigned juvenile male and juvenile and adult female cowbirds to four aviaries and observed patterns of singing and social assortment in each. Although social composition of each aviary was the same, juvenile males in one aviar...
