<br /> ranges based on more local or refined range information and/or information provided by U.S. Fish
<br /> and Wildlife Service biologists with species expertise. All migratory birds that show in areas on land
<br /> in IPaC are those that appear in the 2008 Birds of Conservation Concern report.
<br /> Atlantic Seabirds:
<br /> Ranges in IPaC for birds off the Atlantic coast are derived from species distribution models
<br /> developed by the National Oceanic and Atmospheric Association (NOAA) National Centers for
<br /> Coastal Ocean Science (NCCOS) using the best available seabird survey data for the offshore
<br /> Atlantic Coastal region to date. NOAANCCOS assisted USFWS in developing seasonal species
<br /> ranges from their models for specific use in IPaC. Some of these birds are not BCC species but
<br /> were of interest for inclusion because they may occur in high abundance off the coast at different
<br /> times throughout the year, which potentially makes them more susceptible to certain types of
<br /> development and activities taking place in that area. For more refined details about the abundance
<br /> and richness of bird species within your project area off the Atlantic Coast, see the Northeast
<br /> Ocean Data Portal. The Portal also offers data and information about other types of taxa that may
<br /> be helpful in your project review.
<br /> About the NOAANCCOS models: the models were developed as part of the NOAANCCOS project:
<br /> integrative Statistical Modeling and Predictive Mapping of Marine Bird Distributions and.
<br /> Abundance on the Atlantic Outer Continental Shelf. The models resulting from this project are
<br /> being used in a number of decision-support/mapping products in order to help guide decision-
<br /> making on activities off the Atlantic Coast with the goal of reducing impacts to migratory birds. One
<br /> such product is the northeast Ocean Data Portal, which can be used to explore details about the
<br /> relative occurrence and abundance of bird species in a particular area off the Atlantic Coast.
<br /> All migratory bird range maps within IPaC are continuously being updated as new and better
<br /> information becomes available.
<br /> Can I get additional information about the levels of occurrence in my project area of specific
<br /> birds or groups of birds listed in IPaC?
<br /> Landbirds:
<br /> The Avian Knowledge Network(AKN) provides a tool currently called the "Histogram Tool",which
<br /> draws from the data within the AKN (latest,survey, point count, citizen science datasets)to create a
<br /> view of relative abundance of species within a particular location over the course of the year. The
<br /> results of the tool depict the frequency of detection of a species in survey events, averaged
<br /> between multiple datasets within AKN in a particular week of the year.You may access the
<br /> histogram tools through the Migratory Bird Programs AKN Histogram Tools webpage.
<br /> The tool is currently available for 4 regions (California, Northeast U.S., Southeast U.S. and Midwest),
<br /> which encompasses the following 32 states:Alabama,Arkansas, California, Connecticut, Delaware,
<br /> Florida, Georgia, Illinois, Indiana, Iowa, Kentucky, Louisiana, Maine, Maryland, Massachusetts,
<br /> Michigan, Minnesota, Mississippi, Missouri, New Hampshire, New Jersey, New York, North,
<br /> Carolina, Ohio, Pennsylvania, Rhode Island, South Carolina,Tennessee, Vermont,Virginia, West
<br /> Virginia, and Wisconsin.
