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.

If you enjoy finding tadpoles in ponds, you already know frogs are sensitive to water conditions in some way. This new study explores that sensitivity, asking how amphibians across North America are responding to altered climatic conditions.

A Unified Research Strategy for Disease Management

As wildlife diseases increase globally, an understanding of host-pathogen relationships can elucidate avenues for management and improve conservation efficacy. Amphibians are among the most threatened groups of wildlife, and disease is a major factor in global amphibian declines.

Reproduction and reproductive strategies relevant to management of Whooping Cranes ex situ

Due to the small population size (∼400 birds) and continuing threats to wild Whooping Cranes (Grus americana), an ex situ (captive) population is maintained to contribute to the recovery of the species. The goals of the captive breeding program are to provide opportunity for research and birds for reintroduction. However, reproduction...

Population dynamics of reintroduced Whooping Cranes

Because of the small size and restricted range of the Aransas-Wood Buffalo Population, reintroduction is a prominent element of the recovery effort to ensure persistence of Whooping Cranes (Grus americana). A fundamental objective of all Whooping Crane reintroduction efforts is the establishment of a self-sustaining population. Therefore...
