Research Interests

  • Interfaces of behavior, endocrine and neuroendocrine physiology, ecology, and evolution. Specifically environmental regulation of avian annual schedules of reproduction, plumage molt and migration; scheduling tradeoffs between current reproduction and survival (future reproduction); evolution of mechanisms of responses to environmental cues such as day length, food, social factors; effects of unpredictable environmental events on behavior and physiology of free-living birds.

Areas of Emphasis

  • Physiological Ecology Environmental regulation of avian annual cycles of behavior, physiology and morphology; behavioral and physiological responses of birds to unpredictable environmental events.
