We study the ecology and evolution of host-parasite interactions, particularly those involving birds and parasitic insects. The approaches we use range from experimental tests of the impact of parasites on host fitness, to reciprocal tests of host behavioral and immunological defense, to the analysis of macro-evolutionary patterns of host-parasite co-evolution. We have recently also been studying endosymbiotic bacteria in the ectoparasites we study. Our work includes alpha taxonomy, molecular and morphologically based phylogenetics, experiments with captive birds, and experiments and comparative studies with wild birds. We work on a variety of taxa and their parasites, including pigeons and doves, scrub jays, and Darwin's finches.
