James R. Millam, Ph.D.
Jim Millam joined the Department of Avian Sciences in 1982 after receiving his Ph.D. in animal physiology from the University of Minnesota. His research specialty was avian reproductive physiology with specific interests in gonadotropin-releasing hormone (GnRH) physiology in turkeys, the reproductive physiology and behavior of parrots, and endocrine disruption in songbirds. His research was supported by such agencies as the USDA, NSF, EPA, and DoD, as well as a bequest to the Psittacine Research Project. Dr. Millam was a member of graduate groups in physiology, animal behavior, animal science and avian sciences. His teaching included courses in environmental physiology, avian physiology, avian management and avian reproduction. Professor Millam retired in 2012.

Neural control of turkey reproduction - Most birds breed seasonally and most temperate-clime species limit seasonal reproduction with some form of photorefractoriness, a physiological process that results in gonadal involution. We are using neuroanatomic techniques and exploiting the behavior of long day-induced immediate early gene responses to elucidate neural circuitry mediating photorefractoriness and to learn how thyroid hormone contributes to the development of photorefractoriness.
Parrot behavior - Feather-damaging behavior (FDB)is the single greatest reason companion parrot owners seek veterinary care. We are trying to understand how to provide parrots with behaviorally appropriate environments. For example, we found that providing over-sized pellets that birds can manipulate with beak and feet increases foraging time by hundreds of percent, achieving a much more wild-type behavior pattern. We are currently studying the impact of bathing behavior on natural behavior patterns.
