“…Nevertheless, juvenile sparrows dispersed at least a few kilometers, and 4% moved from one neighborhood to another (Baker and Mewaldt, 1978;Payne, 1981a). The observed dispersal pattern matched also an expected random dispersal model (Hafner and Petersen, 1985), though the trapping program was nonuniform and the dispersal data are difficult to interpret (Baker et aI., 1985). Electromorph estimates of genetic differentiation were also low (F ST = 0.042) in the neighboring dialect sparrow populations, however, no significance tests were reported (Baker et aI., 1982).…”

“…Dispersal within a generation may be sufficient to explain the variation among neighborhoods and to prevent genetic differentiation. It remains an open question whether these song dialects are causally associated with dispersal behavior and genetic differentiation (Zink and Barrowclough, 1984;Zink, 1985;Hafner and Petersen, 1985;Baker et aI., 1985).…”

Abstract. -Neighboring males of indigo buntings (Passerina cyanea) share songs in southern Michigan. We sampled polymorphic enzymes to compare the genetic variation between mates and the variation among contiguous song neighborhoods. Mate choice was independent ofthe genetic and morphometric similarity of female and male, and these measures were independent of each other. The incidence of extrapair copulations and fertilizations was independent ofthe song ofcuckolding males. Breeding success of the mated pairs was independent of their genetic or morphological similarity. Males characterized by different song dialects did not differ in mean lifetime reproductive success. We found no significant genetic differences among the neighborhoods. Most birds that bred in one song neighborhood were born in another, and neighborhoods were not isolated demes. Bunting songs may provide no information to a female about genetic quality of males. The results are consistent with a neutral model of no mate choice for genes.

“…While some studies have found concordance in geographical patterns of acoustic and genetic variation (white-crowned sparrow: Baker (1982), Baker et al (1982Baker et al ( , 1984), many others do not. In a variety of studies, dialects do not correspond with discrete genetic boundaries (rufous-collared sparrow, Zonotrichia capensis: Handford & Nottebohm (1976), Lougheed & Handford (1992), ; white-crowned sparrow: Zink & Barrowclough (1984), Hafner & Petersen (1985); brown-headed cowbird, Molothrus ater : Fleischer & Rothstein (1988); indigo bunting, Passerina cyanea: Payne & Westneat (1988); yellow-naped amazon, Amazona auropalliata: Wright & Wilkinson (2001)). In addition, one study found a correlation between song and genetic variation for some populations, but not for others (swamp sparrow;Balaban (1988a)).…”

The study of bird song dialects was once considered the most promising approach for investigating the role of behaviour in reproductive divergence and speciation. However, after a series of studies yielding conflicting results, research in the field slowed significantly. Recent findings, on how ecological factors may lead to divergence in both song and morphology, necessitate a re-examination. We focus primarily on species with learned song, examine conflicting results in the literature and propose some potential new directions for future studies. We believe an integrative approach, including an examination of the role of ecology in divergent selection, is essential for gaining insight into the role of song in the evolution of assortative mating. Habitat-dependent selection on both song and fitness-related characteristics can lead to parallel divergence in these traits. Song may, therefore, provide females with acoustic cues to find males that are most fit for a particular habitat. In analysing the role of song learning in reproductive divergence, we focus on post-dispersal plasticity in a conceptual framework. We argue that song learning may initially constrain reproductive divergence, while in the later stages of population divergence it may promote speciation.

“…The improved presentation of the geographic patterns of allozyme variation generates several new questions about song variation which had not occurred to us. The intermediate status of the DP sample site (Hafner and Petersen, 1985), for example, can be understood on the basis of what we now know about the microgeographic variation of song elements in that area (Baker and Thompson, 1985). We do contend, however, that the observed long-term stability ofa geographically structured system of song dialects cannot be given a satisfactory evolutionary explanation according to the views that emerge in the discussion by Hafner and Petersen ofthe behavioral data.…”

“…We are grateful to Hafner and Petersen (1985) for reanalyzing our data on genetic structure and dispersal in a sparrow population with song dialects, and for suggesting a new direction for birdsong dialect investigation. In doing so, however, they make some judgments and interpretations with which we disagree.…”
