Despite sharing much of their genomes, males and females are often highly dimorphic, reflecting at least in part the resolution of sexual conflict in response to sexually antagonistic selection. Sexual dimorphism arises owing to sex differences in ge

Bill-wiping, or the scraping by a bird of its bill along a substrate, has been observed in social contexts and cited as an irrelevant displacement activity. However, several behaviors once categorized as displacement behaviors have since been shown t

Perhaps the best way to determine whether and how traits of organisms are currently adaptive is to alter them experimentally and compare the relative fitness of altered and unaltered individuals. We call this method phenotypic engineering. To the ext

The evolution of migration in an animal population produces a suite of physiological, behavioural and cognitive adaptations. Migratory birds, in particular, require the ability to return annually to breeding and wintering sites after long journeys, a

Some secondary sexual traits (SSTs) such as structural characteristics are semi-permanent or static, while others, such as courtship display, are more labile or dynamic. In this paper we report results from two experiments designed to test the relati

Monogamous male birds typically allocate less effort to courtship and more to parental behaviour than males of polygynous species. The seasonal pattern of testosterone (T) secretion varies accordingly. Monogamous males exhibit a spring peak in plasma

Abstract. Several of the reported costs and benefits of testosterone-induced changes in avian breeding behaviour may be mediated by the hormone's effects on spatial activity. Therefore, radiotelemetry was used to monitor the effects of experimentally

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
