Hormones influence many aspects of organismal behavior, physiology, and morphol- ogy, and thus hormones may lie at the root of many life-history trade-offs. By manipulating hormones we can create novel phenotypes (i.e., perform phenotypic engineering

To assess whether alterations in the normal pattern of testosterone (T) secretion might be beneficial or detrimental, we studied a breeding population of darkeyed juncos in which we elevated T experimentally and measured its effect on potential corre

Male dark-eyed juncos, Junco hyemalis , are monogamous and normally help females feed nestlings. We removed males at hatching of their eggs and examined female parental behaviour in response to male removal. We compared parental behaviour of unaided

Prolactin has been associated with incubation and brooding in passerine birds, but its possible association with other parental behaviors remains unclear. We measured plasma concentrations of prolactin (prl) in Dark-eyed Juncos (Bunco hyemalis), a sp

Recent studies of typically monogamous passerine birds have suggested that the fitness benefits males derive by caring for their young may not be as great as was previously thought. This study was conducted to determine whether parental care by male
