Patuxent Wildlife Research Center
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 Patuxent scientists are providing managers with tools for improving detection and for proactively mitigating the impacts of amphibian diseases.More info
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.Read Publication
Undergraduate students with Smithsonian-Mason School of Conservation take a field trip the BBL’s fall migration monitoring station, to learn about bird banding in the field first hand.
Over 5,000 people provided feedback about Reportband.gov as part of an online survey conducted by the University of Baltimore.
Multidirectional abundance shifts among North American birds and the relative influence of multifaceted climate factors
Shifts in species distributions are major fingerprint of climate change. Examining changes in species abundance structures at a continental scale enables robust evaluation of climate change influences, but few studies have conducted these evaluations due to limited data and methodological constraints. In this study, we estimate temporal changes in...Huang, Qiongyu; Sauer, John R.; Dubayah, Ralph O.
Preliminary evaluation of behavioral response of nesting waterbirds to small unmanned aircraft flight
Small unmanned aircraft systems present an emerging technology with the potential to survey colonial waterbird populations while reducing disturbance in comparison to traditional ground counts. Recent research with these systems has been performed on some colonially nesting avian species; however, none have focused on wading bird species. During...Reintsma, Kaitlyn; McGowan, Peter C.; Callahan, Carl R.; Collier, Tom; Gray, David; Sullivan, Jeffery D.; Prosser, Diann J.
Quantifying climate sensitivity and climate-driven change in North American amphibian communities
Changing climate will impact species’ ranges only when environmental variability directly impacts the demography of local populations. However, measurement of demographic responses to climate change has largely been limited to single species and locations. Here we show that amphibian communities are responsive to climatic variability, using >...Miller, David A.W.; Campbell Grant, Evan H.; Muths, Erin L.; Amburgey, Staci M.; Adams, Michael J.; Joseph, Maxwell B.; Waddle, J.
