“…non-breeding context) song. Thus, the data presented here support the emerging idea that zones within LS are functionally distinct and that septal modulation of singing behavior can be influenced by social factors [23,[25][26][27]45]. Taken together with past work, it appears that LS may play an important, but complex, role in the regulation of singing behavior and that social, physiological, and environmental factors may significantly influence how the LS modulates song production.…”

“…Studies in mammals and birds implicate the BST and LS in dominance, aggression, and social signaling used to maintain dominance status [7,9,15,36,38,45,65]. In European starlings, it has been suggested that song produced outside breeding context is used to establish and/or maintain social hierarchies within the large, overwintering flock [64].…”

In songbirds, song learning and production are regulated by the song control system. How the rest of the brain interacts with song nuclei to ensure that song is produced in an appropriate context is not yet clear. In male European starlings (Sturnus vulgaris), breeding context song is sexually motivated whereas non-breeding context song is more broadly socially motivated. Brain regions involved in regulating social behavior might differentially regulate starling song depending upon the context in which it is produced. Here, we compared the number of ZENK-labeled cells in song and social behavior nuclei in starlings singing in either a breeding or a non-breeding context. Numbers of ZENK-labeled cells in HVC related positively to song produced in both contexts. Interestingly, numbers of ZENK-labeled cells in one subdivision of the lateral septum (LS) related negatively to breeding context song but positively to non-breeding context song. In a subdivision of the medial bed nucleus of the stria terminalis (BSTm) ZENK labeling only related positively to non-breeding context song whereas in the ventromedial nucleus of the hypothalamus (VMH) ZENK labeling showed a tighter positive relationship with breeding context song. Together, these findings indicate that social behavior brain regions outside of the song control system regulate singing behavior differently depending upon whether song is sexually or more broadly socially motivated. Breeding context-dependent regulation of song by LS, BSTm, and VMH suggests that these nuclei may be central to adjusting song production so that it occurs in response to appropriate social and environmental stimuli.

“…WS males and females thus exhibit behavior that is more male like than their sex-matched TS counterparts. Alternative behavioral strategies are sometimes characterized by measurable endocrine and neuroendocrine differences between phenotypes (reviewed in Knapp 2003;Spinney et al 2006), and such differences have been detected between the morphs (Maney et al 2005;Spinney et al 2006;Lake et al 2008). The neuroendocrine differences between the plumage morphs therefore suggest a robust but complex mechanism underlying polymorphic social behavior in this species and represent a fascinating example of sexchromosome-independent differentiation of behavior.…”

The Chromosomal Polymorphism Linked to Variation in Social Behavior in the White-Throated Sparrow (Zonotrichia albicollis) Is a Complex Rearrangement and Suppressor of Recombination

Variation in social behavior and plumage in the white-throated sparrow (Zonotrichia albicollis) is linked to an inversion polymorphism on chromosome 2. Here we report the results of our comparative cytogenetic mapping efforts and population genetics studies focused on the genomic characterization of this balanced chromosomal polymorphism. Comparative chromosome painting and cytogenetic mapping of 15 zebra finch BAC clones to the standard (ZAL2) and alternative (ZAL2 m ) arrangements revealed that this chromosome is orthologous to chicken chromosome 3, and that at a minimum, ZAL2 and ZAL2 m differ by a pair of included pericentric inversions that we estimate span at least 98 Mb. Population-based sequencing and genotyping of multiple loci demonstrated that ZAL2 m suppresses recombination in the heterokaryotype and is evolving as a rare nonrecombining autosomal segment of the genome. In addition, we estimate that the first inversion within the ZAL2 m arrangement originated 2.2 6 0.3 million years ago. Finally, while previously recognized as a genetic model for the evolution of social behavior, we found that the ZAL2/ZAL2 m polymorphism also shares genetic and phenotypic features with the mouse t complex and we further suggest that the ZAL2/ZAL2 m polymorphism is a heretofore unrecognized model for the early stages of sex chromosome evolution.
