“…Many attempts have been made to uncover a recognition signal between young and adult cowbirds (Göth & Hauber, 2004;Hauber, Russo, & Sherman, 2001). This study thus joins with others in finding no privileged recognition mechanism (see King & West, 1977) and adds weight to Hauber, Sherman, and Parprika's (2000) account of cowbird recognition as being multifaceted.…”

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 young female birds failed to show same-sex affiliation typical of the species at any point in the study. Brief introduction of adults did not affect social patterns. Adults used more head-down displays than juveniles, who used more displays with familiar peers. Directed and undirected singing emerged concurrently; directed singing was positively correlated with earlier hatching. This is the first demonstration of the need for early learning in the development of female sociality.

“…However, in an experiment with captive birds including four males and two females, I found a straight-line hierarchy (Darley 1978). Also King and West (1977) stated "Data from our laboratory indicated that cowbirds have highly structured dominance hierarchies and complex intraspecific behaviors that may also facilitate identification or maintain social integration among acquainted cowbirds." Some field data supported this view.…”

“…This display can be considered a combination of sexual proceptivity and receptivity. A solicitation display assay (SDA) is commonly used in passerine research to quantify the responsiveness of females to song (King and West, 1977;Brenowitz, 1991;Searcy, 1992). Given the potential for interactions of GnIH and the two avian GnRHs, we sought to determine what effects centrally administered GnIH might have on the known functional outputs of cGnRH-I (gonadotropin release) and cGnRH-II (copulation solicitation).…”

TitleRapid inhibition of female sexual behavior by gonadotropin-inhibitory hormone (GnIH). Abstract Gonadotropin-releasing hormone (GnRH) is largely responsible for the initiation of sexual behaviors; one form of GnRH activates a physiological cascade causing gonadal growth and gonadal steroid feedback to the brain, and another form is thought to act as a neurotransmitter to enhance sexual receptivity. In contrast to GnRH, gonadotropin-inhibitory hormone (GnIH) inhibits gonadotropin release. The distribution of GnIH in the avian brain suggests that it has not only hypophysiotropic actions but also unknown behavioral actions. GnIH fibers are present in the median eminence (ME) and are in apparent contact with chicken GnRH (cGnRH)-I and -II neurons and fibers. In birds, cGnRH-I regulates pituitary gonadotropin release, whereas cGnRH-II enhances copulation solicitation in estradiol-primed females exposed to male song. In the present study, we determined the effects of GnIH administered centrally to female white-crowned sparrows. A physiological dose of GnIH reduced circulating LH and inhibited copulation solicitation, without affecting locomotor activity. Using rhodaminated GnIH, putative GnIH binding sites were seen in the ME close to GnRH-I fiber terminals and in the midbrain on or close to GnRH-II neurons. These data demonstrate direct effects of GnIH upon reproductive physiology and behavior, possibly via separate actions on two forms of GnRH.
