Research Interests

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

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.

Avian communication, especially use of heterospecific mimicry in song, and learned non-song vocalizations.
