Regulation of the HPA axis is related to song complexity and measures of phenotypic quality in song sparrows.

Hormones and behavior - 1 Apr 2012

Abstract excerpt

Regulation of the hypothalamic-pituitary-adrenal (HPA) axis is a key component of the vertebrate stress response. Prior studies have found that variation in HPA responses were correlated to measures of fitness and physiological condition. In addition, sexually-selected traits have also been found to correlate to measures of condition. The proximate mechanisms responsible for such covariation between sexually...
