In species with separate sexes, females and males often differ in their morphology,
physiology and behaviour. Such sex‐specific traits are functionally linked to variation in …

Socially monogamous birds have provided a major focus of research in the field of sexual
selection, providing insight into the evolution of ornaments, sexual dimorphism and sex …

Shifts in the timing of cyclic seasonal life-history events are among the most commonly
reported responses to climate change, with differences in response rates among interacting …

Ultimate factors such as food availability and weather create optimal windows of time for
birds to reproduce. However, within a given year, birds must rely upon proximate …

Climate change is expected to increase the prevalence and severity of extreme weather
events like drought. For many opportunistically breeding tropical bird species, precipitation …

In many species that form pair bonds, males display to their mate after pair formation. These
displays elevate the female's investment into the brood. This is a form of cooperation …

Many species have shifted their breeding phenology in response to climate change.
Identifying the magnitude of phenological shifts and whether climate‐mediated selection …

Many organisms use environmental cues to time events in their annual cycle, such as
reproduction and migration, with the appropriate timing of such events impacting survival …

Many animals rely on photoperiodic and non-photoperiodic environmental cues to gather
information and appropriately time life-history stages across the annual cycle, such as …

It is widely assumed that female birds use nonphotic supplemental cues, including social
factors, to fine-tune timing of egg-laying to local conditions, but our knowledge of the nature …
