Bird Population Studies

We study disease, environmental changes, and the complex web of factors that determine where birds are found and how abundant they can become.

    Emerging Wildlife Diseases and Ecology

    We study the evolutionary ecology of an emerging wildlife disease, including changes in a bacterial pathogen and its impacts on new hosts, including House Finches.

    Wild Birds and Poultry Diseases

    We examine the frequency of movement of pathogens between domestic poultry and wild songbirds, and potential economic impacts of disease transmission.

    Impact of Multiple Pathogens on Wild Birds

    We study the combined effect of multiple pathogens on wild birds to understand how coinfections affect disease severity and dynamics, including infections of new hosts.

    Distribution and Abundance of Birds

    Using data-intensive science, we work with colleagues from around the Cornell Lab to reveal biological insights from massive data sets, including eBird and Project FeederWatch.
