Searching for the functional origins of song in eastern brown-headed cowbirds, Molothrus ater ater
Animal Behaviour, 1988Abstract Three experiments were conducted to examine the functional properties of vocal precursors to stereotyped song in socially housed captive cowbirds. Previous studies had shown that eastern male cowbirds developed different song repertoires when housed in different social contexts.

In this article we report that imitation and improvisation of tutor songs by eastern male cowbirds (Molothrus ater ater) differs when they are housed with conspecific females as opposed to nonconspecifics. When males, tutored with 12 different song types, were individually housed with females, they developed repertoires composed primarily of improvised

Two measures of temporal resolution in brown-headed cowbirds (Molothrus ater)
Journal of Comparative Physiology A, 2011Studies of auditory temporal resolution in birds have traditionally examined processing capabilities by assessing behavioral discrimination of sounds varying in temporal structure. Here, temporal resolution of the brown-headed cowbird (Molothrus ater) was measured using two auditory evoked potential (AEP)-based methods: auditory brainstem responses ...

The cultural transmission of courtship patterns in cowbirds,Molothrus ater
Animal Behaviour, 1998In this study, I tested whether the courtship behaviours that facilitate patterns of assortative pairing and mating could be culturally transmitted across generations of brown-headed cowbirds. In an earlier study, I housed a first generation of young South Dakota cowbirds in one of two cultural backgrounds: (1) with adult social models from the same ...

Sex differences in auditory filters of brown-headed cowbirds (Molothrus ater)
Journal of Comparative Physiology A, 2010Receiver sensory abilities can be influenced by a number of factors, including habitat, phylogeny and the selective pressure to acquire information about conspecifics or heterospecifics. It has been hypothesized that brood-parasitic brown-headed cowbird (Molothrus ater) females may locate or determine the quality of potential hosts by eavesdropping on ...

Developmental origins of sociality in brown-headed cowbirds (Molothrus ater).
Journal of Comparative Psychology, 2006Five 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 ...

Developmental Psychobiology, 1987
AbstractHere we report data requiring a reinterpretation of published results on the female cowbird's (Molothrus ater ater) ability to identify male song (King, A. P., and West, M. J. (1983). Female perception of cowbird song: A closed developmental program. Dev. Psychobiol., 16:335–342).

The social experiences of young Molothrus ater ater cowbirds were manipulated in a 2-year study. In the 1st year, males were housed with pairs of canaries. The males were tested in 3 social contexts. Also, vocal repertoires were recorded and played back to females. In contrast to a previous study of the M. a.

Cultural influences on female mate choice: an experimental test in cowbirds,Molothrus ater
Animal Behaviour, 1999Previous studies of brown-headed cowbirds Molothrus ater, have shown that social learning and cultural transmission can influence courtship and mating patterns. These earlier studies did not test whether cultural background influenced mate choice in females and therefore whether culture could potentially play a role in sexual selection in this species,
