Wildlife Ecology


I am interested in the ecology of wild creatures, with particular emphasis on birds.  I have been fortunate to participate in fieldwork, design experiments and act as a peer reviewer for numerous research projects aimed at increasing our understanding of how animals survive and thrive near and distant from human activities.   My current doctoral research seeks patterns of species coexistence in bird communities following the loss of forest and subsequent residential development here in the Puget Lowlands of Western Washington.  My M.Sc. research evaluated wildlife response (nesting songbirds and associated avian and mammalian nest predators) to recreation sites in riparian forest patches (CO).  In addition, I have assisted on field projects involving burrowing owls (MT), American dippers (MT), peregrine falcons (WA), northern goshawks (WA) and song sparrows (WA).
