title: Data from: Female ornamentation is associated with elevated aggression and testosterone in a tropical songbird

description: In males, testosterone plays a key role in ornament production and linking
 ornamentation with reproductive behaviors and other traits to produce an
 integrated phenotype. Less is known about whether females couple
 testosterone, ornamentation, and aggressive behaviors to achieve
 female-specific combinations of traits. Ornamentation in females may be
 the result of correlated expression with male ornamentation, or female
 traits could arise as the result of sex specific selection pressures.
 Resolving between these alternatives is necessary to understand the degree
 to which selection acts on female traits. The White-shouldered Fairywren
 (Malurus alboscapulatus) provides a useful context to address these
 questions because populations vary in degree of female ornamentation, a
 derived trait, whereas male ornamentation is constant across both
 populations. We found that ornamented females have higher levels of
 circulating testosterone and respond more aggressively to experimental
 territorial intrusions than do unornamented females. These findings are
 consistent with the idea that, among female White-shouldered Fairywrens,
 testosterone may mechanistically link plumage and behavioral traits to
 produce an integrated competitive phenotype, as has been reported for
 males of closely related species. In contrast, circulating testosterone in
 males did not differ significantly between populations. More broadly, our
 findings are consistent with ongoing selection on the mechanisms
 underlying female ornaments, likely via social selection.
