This data set contains sensitive biological resource data for wading birds, shorebirds, waterfowl, raptors, diving birds, seabirds, passerine birds, and gulls and terns in Chesapeake Bay and the Outer Coasts of Maryland and Virginia. Vector polygons (BIRD POLYS) in this data set represent bird nesting, migratory staging, and wintering sites, general distributions, and concentration areas. Vector points (BIRD POINTS) in this data set represent bird nesting and roosting sites. Species specific abundance, seasonality, status, life history, and source information are stored in relational data tables (described below) designed to be used in conjunction with this spatial data layer. This data set comprises a portion of the ESI data for Chesapeake Bay and the Outer Coasts of Maryland and Virginia. ESI data characterize the marine and coastal environments and wildlife by their sensitivity to spilled oil. The ESI data include information for three main components: shoreline habitats, sensitive biological resources, and human-use resources. The ESI data were collected, mapped, and digitized to provide environmental data for oil spill planning and response. The Clean Water Act with amendments by the Oil Pollution Act of 1990 requires response plans for immediate and effective protection of sensitive resources. This project was supported by the National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), Office of Response and Restoration (OR&R), Emergency Response Division (ERD), Seattle, Washington. completed ESI Program Manager 7600 Sand Point Way NE Seattle WA 98115 orr.esi@noaa.gov pointOfContact ESI Program Manager 7600 Sand Point Way NE Seattle WA 98115 orr.esi@noaa.gov custodian asNeeded Data content is considered static once published.

The process includes a standardized data entry methodology, data review by in-house and external resource experts, a final Quality Assurance/Quality Control (QA/QC) process, and multiple automated logical consistency checks. Quantitative data (such as densities, counts, abundances, or concentrations) provided by resource experts for inclusion in the data set may vary widely in attribute accuracy, depending upon the methodology used to collect and compile such data. For a more detailed evaluation of source data attribute accuracy, contact the sources listed in the Lineage section. Horizontal Positional Accuracy Spatial components for the biological data layers can come from expert interviews, hardcopy, or digital sources. Some of the spatial components of the biological data layers may have been developed using regional experts who estimate concentration areas. It is difficult to estimate the positional accuracy of such data, except to state that they are compiled on hardcopy base maps with a scale of 1:24,000. Some of the spatial components of the biological data sets are developed from pre-existing digital or hardcopy sources and reflect the positional accuracy of these original data. Note that biological resource data by their very nature are considered "fuzzy", and this should be understood when considering the positional accuracy of vector digital objects representing these resources. See the Lineage and Process_Description sections for more information on the original source data and how these data were integrated or manipulated to create the final data set. Completeness Report These data represent a synthesis of expert knowledge, available hardcopy documents, survey data, maps, and digital data on birds in the study area.

Conceptual Consistency A multi-stage error checking process, described in the above Attribute Accuracy Report, is used to verify both attribute accuracy and logical consistency throughout data production. This process includes multiple automated logical consistency checks that test the files for missing or duplicate data, rules for proper coding, GIS topological consistencies, and SQL SERVER(R) to ArcGIS(R) consistencies. A final review is made by the GIS manager, before the final Geodatabase and metadata are created. After the data are delivered to NOAA, they are again subjected to several consistency checks, and processed into the final delivery format. This atlas supersedes two prior atlases, Virginia (2005, #25) and Maryland (2007, #47). Three main sources of data were used to depict bird distribution and seasonality: 1) personal interviews with resource experts from the Virginia Department of Game and Inland Fisheries (VDGIF), Maryland Department of Natural Resources (MD DNR), National Park Service (NPS), Center for Conservation Biology (CCB), The Nature Conservancy (TNC), Saltmarsh Habitat and Avian Research Program (SHARP), and U.S. Fish and Wildlife Service (USFWS); 2) digital survey data from VDGIF, MD DNR, NPS, CCB, TNC, USFWS, and SHARP; and 3) numerous published and unpublished reports. Shorebirds, diving birds, gulls and terns: Survey data on locations of breeding, migrating, and/or wintering species were provided by various agencies via shapefiles, spreadsheets, primary literature, and expert local knowledge, and was supplemented with information from eBird. In general, data from the various data sources were compiled and mapped to habitat, park/refuge, or specific locations, per expert recommendations. There is additional source information in the GIS data tables. 2016-09-01T00:00:00 ESI Program Manager orr.esi@noaa.gov processor Colonial waterbird nesting areas: For Virginia, VDGIF provided nesting datafrom 2013 that originated from various partner organizations including CCB, VDGIF, TNC, VA DCR, USFWS, USGS, and College of William and Mary. For Maryland, MD DNR provided nesting data from annual surveys conducted between 2004-2013. Each nesting colony was buffered by 200 m. Overlapping nest locations were merged, and counts from the dissolved colonies summed. Additionally, CCB provided nesting heron and egret survey data for the entire Chesapeake Bay drainage area (including MD), also from 2013. Where the heron/egret colonies overlapped with the VA colonial waterbird colonies, the heron/egret counts were added to the existing colony. Elsewhere, the heron and egret survey locations were mapped as points with counts of pairs for each species for each point location. 2016-09-01T00:00:00 ESI Program Manager orr.esi@noaa.gov processor Wintering and nesting waterfowl: In Maryland, diving ducks and geese along the Chesapeake Bay were mapped into Areas of Critical State Concern for waterfowl (defined under Maryland's State Planning enabling legislation, article 88C). In coastal bays these species were mapped with a 250m offshore buffer based on MD DNR surveys (2013-2014). Dabbling ducks were mapped based on USFWS mid-winter survey blocks and MD DNR coastal bay surveys with a 250m onshore/offshore buffer. In Virginia, species were mapped according to areas defined by VDGIF when compiling aerial survey data for USFWS mid-winter surveys (2004-2015) and expert knowledge. Counts were binned into Present (less than 10), 10s, 100s, 1,000s, or 10,000s. Nesting waterfowl occurrences in Maryland were derived from the Second Atlas of the Breeding Birds of Maryland and the District of Columbia and MD DNR expert knowledge; they are mapped as a 250m onshore buffer. In Virginia, American black duck nesting distributions were mapped based on VDGIF expert knowledge; mallard and Canada goose were mapped using species' presence during mid-winter surveys in or near marsh habitats; and wood duck were mapped using species' presence during mid-winter surveys in swamps and freshwater marshes. Nesting concentrations for waterfowl are represented as Present, Low, Moderate, High, or Very High. Onshore buffers that intersected with larger areas of freshwater or salt-and brackish-water marsh included those areas as part of the mapped distribution. Numbers from wintering surveys are likely underestimates, since surveys do not necessarily occur during each species' months of peak abundance. 2016-09-01T00:00:00 ESI Program Manager orr.esi@noaa.gov processor Atlantic Ocean and Chesapeake Bay seabirds: Distribution of pelagic birds, gulls, terns, diving birds, alcids, phalaropes, and waterfowl in open waters of Chesapeake Bay and tributaries and the Atlantic Ocean (nearshore and offshore) were generated from discussions with resource experts, reports, and survey data. Species in open waters of Chesapeake Bay and the Atlantic Ocean were mapped from compiled aerial and shipboard survey data from USFWS that included: USFWS Atlantic Coast Wintering Sea Duck Surveys (ACWSD; preliminary survey in 2008, full surveys 2009-11), USFWS Atlantic Marine Assessment Program for Protected Species (AMAPPS) seabird surveys (preliminary survey in 2010, full-coast surveys in summer 2011, spring and fall 2012, winter 2014), NOAA EcoMon surveys, and Department of Energy (DOE)/Biological Research Institute (BRI) surveys (2012-2014). Distribution in Chesapeake Bay tributaries were mapped from USFWS midwinter surveys (2004-2015), BRI reports (2015), and eBird records from 2004-2016. Based on frequency of occurrence, abundance in these areas, and expert advice, data were grouped to create divisions throughout Chesapeake Bay and its tributaries, at the mouth of Chesapeake Bay, and as offshore polygons made as either a 0-5 nautical mile (nm) offshore buffer or a 0-12 nm offshore buffer. Counts were binned into Present (less than 10), 10s, 100s, 1,000s, or 10,000s. 2016-09-01T00:00:00 ESI Program Manager orr.esi@noaa.gov processor Raptors: Bald eagle nest survey data (2015) was provided by CCB for Virginia. Nest locations were mapped as points in the ESI. Recent bald eagle nest survey data was not available for MD, as the state no longer surveys for the species. Historical data (1988-2010) of MD nest locations were mapped as points with the last observation date noted in the ESI concentration field. According to local experts, bald eagle nests are common in the state and the historical dataset is incomplete and does not fully cover where the species currently nests. VDGIF provided a Bald Eagle Concentration and Roosts (BECAR) dataset which features concentration areas along shorelines that have been identified through surveys to support a high density of non-breeding bald eagles in summer and/or winter. Roost sites are sites that have been documented as repeatedly used as night-time resting places for multiple bald eagles, and are displayed as both polygons (based on the VDGIF BECAR data set) and points (based on the CCB data set). Peregrine falcon and osprey nest sites were mapped based on expert knowledge and/or nesting survey data. Northern harrier was mapped based on expert knowledge. 2016-09-01T00:00:00 ESI Program Manager orr.esi@noaa.gov processor Secretive marsh birds: Black rail (VA SE) detection data for Virginia was provided by CCB for 2007-2008 and 2014. Data from both datasets largely overlapped, so the datasets were combined for the ESI. Points were buffered by 200 m. Patch analysis data for clapper rail, saltmarsh sharp-tailed sparrow, seaside sparrow, and willet were provided by SHARP. The patch analysis used habitat data from NWI to delineate marsh patches, and used field surveys of the target species to model species densities in each patch. Species densities were converted to number of birds per square kilometer and mapped to the appropriate marsh patches. Additionally, there were four SHARP survey sites on the western side of the Chesapeake Bay that had detected clapper rails in numbers too low for patch analysis. These survey sites were mapped as 50 m buffer polygons. NPS provided survey data of the following marsh birds on Assateague Island: clapper rail, king rail, saltmarsh sharp-tailed sparrow, and seaside sparrow. Each survey location with birds detected was mapped with a 200 m buffer. Where overlap occurred between SHARP data and NPS data, SHARP data was used because it contained more detailed spatial and concentration information. 2016-09-01T00:00:00 ESI Program Manager orr.esi@noaa.gov processor Rare birds: A few rare bird species were mapped using data supplied by MD DNR from their Ecologically Significant Areas database. Data from this program came in the form of large generalized polygons that often include the presence of more than one species. Bird species mapped from this data set include: American bittern, black rail (MD SE, VA SE), black skimmer (MD SE), common moorhen, gull-billed tern (MD SE, VA ST), least bittern, peregrine falcon (VA ST), and royal tern (MD SE). 2016-09-01T00:00:00 ESI Program Manager orr.esi@noaa.gov processor BIRD POLYS: Data from the above sources were compiled by the project biologist to create the BIRD POLYS data layer. Three general approaches are used for compiling the data layer: 1) information gathered during initial interviews and from hardcopy sources are compiled onto U.S. Geological Survey 1:24,000 topographic quadrangles and digitized; 2) hardcopy maps are digitized at their source scale; 3) digital data layers are evaluated and used "as is" or integrated with the hardcopy data sources. See the Lineage section for additional information. Once the ESI, biology, and human-use data are compiled into the standard ESI digital data format, a second set of interviews with participating resource experts are conducted to review the compiled data. If necessary, edits to the BIRD POLYS data layer were made based on the recommendations of the resource experts, and final hardcopy maps and digital data are created. 2016-09-01T00:00:00 ESI Program Manager orr.esi@noaa.gov processor BIRD POINTS: Three main sources of data were used to depict bird distribution and seasonality for the BIRD POINTS data layer: 1) personal interviews with resource experts from the Virginia Department of Game and Inland Fisheries (VDGIF), Maryland Department of Natural Resources (MD DNR), Center for Conservation Biology (CCB), and U.S. Fish and Wildlife Service (USFWS); 2) digital survey data from VDGIF, MD DNR, and CCB; and 3) published and unpublished reports. CCB provided nesting heron and egret survey data for the entire Chesapeake Bay drainage area (including MD) from 2013. Herons and Egrets: Where the heron/egret colonies overlapped with the VA colonial waterbird colonies, the heron/egret counts were added to the existing colony. Elsewhere, the heron and egret survey locations were mapped as points with counts of pairs for each species for each point location. Raptors: Bald eagle nest survey data (2015) was provided by CCB for Virginia. Nest locations were mapped as points in the ESI. Recent bald eagle nest survey data was not available for MD, as the state no longer surveys for the species. Historical data (1988-2010) of MD nest locations were mapped as points with the last observation date noted in the ESI concentration field. According to local experts, bald eagle nests are common in the state and the historical dataset is incomplete and does not fully cover where the species currently nests. Roost sites are sites that have been documented as repeatedly used as night-time resting places for multiple bald eagles, and are displayed as both polygons (based on the VDGIF BECAR data set) and points (based on the CCB data set). Peregrine falcon and osprey nest sites were mapped based on expert knowledge and/or nesting survey data. Northern harrier was mapped based on expert knowledge.
