Avian Ecologist

I am an evolutionary ecologist who works with birds and other taxa. My research interests include ecology of human-dominated landscapes (including the urban environment), ecosystem services, plant-animal interactions, and interplay of digestive physiology and foraging ecology. A common theme that unites my research interests is consumer-resource theory. As consumers, birds play many functional roles in the ecosystems they inhabit, including pest control and seed dispersal. As resources themselves, bird communities are often strongly impacted by predation, particularly nest predation. A central goal is building fundamental understanding of the evolutionary ecology of birds in ways that can promote sound land and resource management while enhancing bird species conservation.
 
My work, over many years, has investigated a wide variety of phenomena, including foraging ecology of New World warblers, seeking insights into their resource exploitation systems, habitat selection, and community organization; predation by insectivorous birds on the invasive gypsy moth caterpillar (with Richard Holmes); phenological causes and consequences of fruit consumption and seed dispersal by migratory songbirds (with Mary Willson); avian pest control of forest leaf-chewing insects (with Robert Marquis). More recently I teamed with Illinois Natural History Survey colleagues to examine potential ecological effects of rail transportation corridors and infrastructure in the upper Midwest. I strive to cultivate collaborations that promote integration of scientific approaches and disciplines
Research:
I am an evolutionary ecologist with a primary focus on birds, and their functional, ecological roles in ecosystems. By their function, birds help sculpt the landscapes they inhabit and deliver many critical ecosystem services.
 
Over my career, I have worked in the following major areas:
 
Foraging ecology, habitat selection, and community structure; interactions among birds and arthropod prey; evolutionary ecology of bird-plant interactions; integrating digestive physiology and foraging ecology; evolutionary game theory; functional roles of birds in ecosystems and ecosystem services
