Patuxent Wildlife Research Center

Home

Patuxent Wildlife Research Center (PWRC) produces innovative science to support natural resource management and meet our nation’s most pressing conservation challenges.
PWRC research topics include bird population dynamics, ecotoxicology, and the development of quantitative & decision analysis tools. We conduct several national programs, including the Bird Banding Lab and the Breeding Bird Survey.

USGS Celebrates 100 Years of Bird Banding Lab

Birds bring joy merely by their presence, from their bold colors and majestic songs to their grace as they glide through the sky. Birds contribute more than beauty to the environment and society. Many plants depend on hummingbirds and other species to pollinate them. Hawks and owls prey on rodents and other pests. Fruit- and grain-eating birds help spread plants’ seeds.

Seasonality of acarological risk of exposure to Borrelia miyamotoi from questing life stages of Ixodes scapularis collected from Wisconsin and Massachusetts, USA

Measures of acarological risk of exposure to Ixodes scapularis-borne disease agents typically focus on nymphs; however, the relapsing fever group spirochete, Borrelia miyamotoi can be transmitted transovarially, and I. scapularis larvae are capable of transmitting B. miyamotoi to their hosts. To quantify the...

Principles and mechanisms of wildlife population persistence in the face of disease

Emerging infectious diseases can result in species declines and hamper recovery efforts for at-risk populations. Generalizing considerations for reducing the risk of pathogen introduction and mitigating the effects of disease remains challenging and inhibits our ability to provide guidance for species recovery planning. Given the growing rates of...
