Adkins Regan E. Male-male sexual behavior in Japanese quail: being "on top" reduces mating and fertilization with females. Behav Processes. 2014;108:71-9 pubmed publisher
..Instead, the results are consistent with male-male sexual behavior as an occasionally costly by-product of strong mating motivation. ..
Smiley K, Adkins Regan E. Factors that influence the onset of parental care in zebra finches: Roles for egg stimuli and prolactin. Behav Processes. 2018;153:47-54 pubmed publisher
..Our results suggest that both eggs and chicks are sufficient to stimulate foster care, perhaps through endogenous prolactin signalling, while further elevations of prolactin may serve to synchronize parental behaviors between pairs. ..

..Mechanisms for and responses to vasotocin (avian vasopressin) in the septal region of the brain are predicted by sociality in this group of birds. ..

Smiley K, Adkins Regan E. Lowering prolactin reduces post-hatch parental care in male and female zebra finches (Taeniopygia guttata). Horm Behav. 2018;98:103-114 pubmed publisher
..This is one of the few causal studies to demonstrate that PRL is necessary for post-hatch care in a biparental songbird, and is the first to show this effect in zebra finches. ..
