Constructing culture in cowbirds (Molothrus ater).
In past work, the authors produced divergent patterns of courtship and communication in juvenile male cowbirds (Molothrus ater) by providing them with different social experiences during their 1st year. Here the authors determined whether these different social patterns could be transmitted to new generations of juvenile males. In Experiment 1, the authors exposed groups of juveniles to adult m...
متن کاملRobust Fall Social Displays Predict Spring Reproductive Behavior in BrownHeaded Cowbirds (Molothrus ater ater)
The ability to engage others in close proximity may be an essential component of social life and shapes the development of social skills. Variation in the willingness to initiate and sustain close interaction with conspecifics is known as sociability. The Brown-headed Cowbird (Molothrus ater) uses an affiliative display called the head-down to bring individuals into close proximity. During fall...
متن کاملIn the company of cowbirds, Molothrus ater ater: robust patterns of sociability predict reproductive performance.
Many species exhibit behavioral tendencies that are stable over time and across contexts. Robust variation in sociability, or the propensity to approach others, is widespread across the vertebrates. Nonetheless, the influence of sociability on reproductive performance is largely unknown. In this study, we explore the relationship between sociability and reproductive behavior in flocks of Brown-...
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 کاملFacultative development of courtship and communication in juvenile male cowbirds (Molothrus ater)
We investigated effects of naturally occurring variation in experience with adult males on development of song and courtship competence in captive juvenile cowbirds. We studied birds in groups housed in large outdoor aviaries that allowed birds to regulate access to social stimulation. In two aviaries, we housed juvenile males and females either with or without adult males. Birds remained in th...
