Keith is the National Coordinator for the USGS North American Breeding Bird Survey (BBS) at the Eastern Ecological Science Center in Laurel, MD.
The USGS North American Breeding Bird Survey (BBS), an international avian monitoring program that provides annual population data for more the 600 bird species, providing a quantitative cornerstone of bird conservation and management in the U.S. and Canada. Each year the project entails mobilizing thousands of highly skilled professional and citizen scientists across 49 states, managing data entry processes, a 90-million-record MS-SQL database that spans 54 years, and approximately 5,000 sample locations, as well as collaborating with partners and stakeholders to address developing national concerns while improving the program’s core strengths.

North American Breeding Bird Survey Results and Analysis
This website provides visualizations of population change for North American birds using data from the North American Breeding Bird Survey (BBS). The BBS is analyzed for a "core" area (contiguous United States and southern Canada, results available from 1966-present), and for an "expanded" survey area (including portions of Alaska and northern Canada with results from 1993-present).

Spatio-Temporal Statistical Models for Forecasting Climate Change Effects on Bird Distribution
Ecological indicators of climate change are needed to measure concurrent changes in ecological systems, inform management decisions, and forecast the consequences of climate change. We seek to develop robust bird-based, climate-change indicators using North American Breeding Bird Survey data.Comprehensive 1966 - 2017 Results! North American Breeding Bird Survey

The Challenge: Since 1966, the North American Breeding Bird Survey (BBS) has filled a vital role in identifying at-risk bird species for Federal, State, and private entities. The BBS is a scientifically rigorous population count performed by a highly skilled, largely volunteer work force of nearly 2,500 observers. Every year these observers visit most of the survey’s 4,500 routes, which consist of...Avian Indicators of Climate Change Based on the North American Breeding Bird Survey
Appropriate ecological indicators of climate change can be used to measure concurrent changes in ecological systems, inform management decisions, and potentially to project the consequences of climate change. However, many of the available indicators for North American birds do not account for imperfect observation. We proposed to use correlated-detection occupancy models to develop indicators fro - Data

Strategic Plan for the North American Breeding Bird Survey, 2020–30
The North American Breeding Bird Survey (BBS) has been the cornerstone of continental bird conservation and management for hundreds of North American bird species in the United States and Canada for more than 50 years. This strategic plan was developed in collaboration with key partners and stakeholders and charts the ambitious course for the BBS over the next decade (2020–30). Using this plan asAuthors,Migratory behavior and winter geography drive differential range shifts of eastern birds in response to recent climate change
Over the past half century, migratory birds in North America have shown divergent population trends relative to resident species, with the former declining rapidly and the latter increasing. The role that climate change has played in these observed trends is not well understood, despite significant warming over this period. We used 43 y of monitoring data to fit dynamic species distribution modelsAuthorsClark Rushing, Andy Royle, David Ziolkowski, Keith L. PardieckModeling spatially and temporally complex range dynamics when detection is imperfect
Species distributions are determined by the interaction of multiple biotic and abiotic factors, which produces complex spatial and temporal patterns of occurrence. As habitats and climate change due to anthropogenic activities, there is a need to develop species distribution models that can quantify these complex range dynamics. In this paper, we develop a dynamic occupancy model that uses a spatiAuthorsClark S. Rushing, J. Andrew Royle, David Ziolkowski, Keith L. PardieckConsistency counts: Modeling the effects of a change in protocol on Breeding Bird Survey counts
Analysis of North American Breeding Bird Survey (BBS) data requires controls for factors that influence detectability of birds along survey routes. Identifying factors that influence the counting process and incorporating them into analyses is a primary means of limiting bias in estimates of population change.

Does it seem like you are hearing fewer Northern Bobwhite (Colinus virginianus) calls in recent years than you remember when you were younger? Conversely, have you also noticed hearing more “cooing” of Eurasian Collared-Doves (Streptopelia decaocto)? Do such experiences reflect changes in bird populations or are they false impressions? Well, fortunately for us, we have one of the most powerful wilAuthorsDaniel J. Twedt, Keith L. PardieckThe role of the North American Breeding Bird Survey in conservation
The North American Breeding Bird Survey (BBS) was established in 1966 in response to a lack of quantitative data on changes in the populations of many bird species at a continental scale, especially songbirds. The BBS now provides the most reliable regional and continental trends and annual indices of abundance available for >500 bird species.

PardieckHow well do route survey areas represent landscapes at larger spatial extents? An analysis of land cover composition along Breeding Bird Survey routes
The occurrence of birds in a survey unit is partly determined by the habitat present. Moreover, some bird species preferentially avoid some land cover types and are attracted to others. As such, land cover composition within the 400 m survey areas along a Breeding Bird Survey (BBS) route clearly influences the species available to be detected. Ideally, to extend survey results to the larger landscAuthorsJoseph A. Veech, Keith L. Pardieck, David ZiolkowskiThe first 50 years of the North American Breeding Bird Survey
The vision of Chandler (Chan) S. Robbins for a continental-scale omnibus survey of breeding birds led to the development of the North American Breeding Bird Survey (BBS). Chan was uniquely suited to develop the BBS. His position as a government scientist had given him experience with designing and implementing continental-scale surveys, his research background made him an effective advocate of theAuthorsJohn R.

The North American Breeding Bird Survey (BBS) contains data for >700 bird species, but analyses often focus on a core group of ∼420 species.

Integrated population models (IPMs) provide a unified framework for simultaneously analyzing data sets of different types to estimate vital rates, population size, and dynamics; assess contributions of demographic parameters to population changes; and assess population viability. Strengths of an IPM include the ability to estimate latent parameters and improve the precision of parameter estimates.AuthorsFarshid S. Ahrestani, James F. Saracco, John R. Sauer, Keith L. Pardieck, J. Andrew RoyleEstimating indices of range shifts in birds using dynamic models when detection is imperfect
There is intense interest in basic and applied ecology about the effect of global change on current and future species distributions. Projections based on widely used static modeling methods implicitly assume that species are in equilibrium with the environment and that detection during surveys is perfect. We used multiseason correlated detection occupancy models, which avoid these assumptions, toAuthorsMatthew J. Clement, James E. Hines, James D. Nichols, Keith L. Pardieck, David J.
