Estrogens regulate a variety of social behaviors, including appetitive and consummatory sexual behavior, social affi liation, and aggression. Much of our understanding of the roles of estrogens in social behavior comes from laboratory studies of domesticated mice and rats (Blumstein et al., 2010; Soma et al., 2008). In addition to this work, fi eld studies of free-living animals off er the opportunity to investigate how estrogens regulate naturally occurring social behaviors within an ecologically relevant context. Such work is important because it has provided novel insights and perspectives into the estrogenic regulation of complex social behaviors and has been critical to developing a comprehensive understanding of the variety of contexts in which estrogens regulate social behavior. One such example is research on the role of 17 β -estradiol (E 2 ) in regulating male song sparrow ( Melospiza melodia ) territorial aggression in diff erent seasons. Our understanding of songbird natural history, behavior, social patterning, and seasonal endocrine physiology is far greater than for most vertebrates. Song sparrows played a critical role in the formulation of principles about testosterone and aggression, such as the Challenge Hypothesis described by Wingfi eld et al. (1990). Further, the songbird brain expresses the estrogen-synthetic enzyme aromatase more widely and in higher abundance than nonsongbird species, including rodents (Forlano et al., 2006). Moreover, songbird behavior and adult neuroplasticity are highly estrogen sensitive and seasonally variable (Ball et al., 2004; Soma, 2006; Schlinger et al., 2008). Together, these factors make songbirds outstanding model systems for studying estrogenic regulation of complex social behaviors.
