|Dr. Mark E. Hauber is professor and director of the Animal Behavior and Conservation program in the Department of Psychology at Hunter College of the City University of New York. He is a native of Hungary, a graduate of Yale and Cornell Universities, and received postdoctoral training as a Miller Fellow at UC Berkeley. Previously Mark taught at the University of Auckland's School of Biological Sciences. A recipient of NSF and Human Frontier Science grants, Dr. Hauber has published over 200 peer-reviewed articles, and penned the University of Chicago Press' The Book of Eggs (2014).
The development of the recognition of self-like individuals, including relatives and conspecifics, often relies on critical experience with parents, siblings, and other predictable referents during early life. For example, in birds, exposure to conspecifics in the nest reliably cues species-recognition for flocking and mating. How then so brood parasitic birds, that lay their eggs in other species' nest, develop conspecific referents when raised by foster parents? And how do hosts recognize and reject foreign eggs and chicks in the nest if they have not yet laid a clutch before? The presenter’s research focuses on the experimental analysis of self-recognition in both parasites and hosts through phenotypic manipulation of the available cues for species recognition during development. The results reveal how a long-hypothesized mechanism, namely self-referenced phenotype matching, enables the evolution of brood parasitism in birds, and perhaps contributes to the ecological flexibility of recognition systems under socially unpredictable conditions in general.
|Learning Objectives: At the conclusion of the presentation, the participant will be able to: (1) define the terms "conspecific" and "heterospecific"; (2) name at least two species of brood parasitic birds; (3) state at least two parallels between the reproductive and communicative behaviors of birds and humans.
