I am interested in avian social behavior and I ask questions from an evolutionary perspective. I use a combination of field observations, experiments in natural populations and molecular genetic techniques in the laboratory. I am currently studying social groups of the cooperatively breeding acorn woodpecker, addressing questions including the following. How do individuals in social groups of up to 15 adults share reproduction? Do the theoretical models of reproductive partitioning that were developed largely for social invertebrates work well for helping to understand social vertebrates? Is incest avoided? When and under what circumstances do individuals in social groups attempt to disperse to other social groups? Do individuals that are genetic parents of the offspring produced in a group contribute more to their care and protection then other members of the group? In addition to molecular work in my lab, my research students have the opportunity to participate in summer research at my study site, Hastings Natural History Reservation.
