Alan is broadly interested in organismal evolution, particularly in the evolution of cooperation, sexual selection, and signaling systems. Much of his work involves the study of complex avian mating systems as a way to understand the relationship between the social, biotic, and physical environment and individual behavioral strategies. For example, we expect males to compete vigorously in many polygynous breeding systems, so why do we see cooperative behavior emerge in some species, and what factors might explain why these cooperative strategies differ across taxa?  Additionally, much of the foundational work on sexual selection has focused on static traits, yet one only has to watch animal courtship for a brief time to see the interactive nature of this process. So how and why do males vary their courtship displays in response to the changes in their environment, and is the ability to express variation in itself important for fitness?  He addresses these and other questions using a variety of field and lab techniques, including molecular estimates of relatedness and parentage, multi-channel microphone arrays, high-definition video, photography, playback experiments, and radiotelemetry. He has mentored more than 200 undergraduate research assistants and post-graduate field technicians during the course of these projects.
