Chesapeake Bay and the Outer Coasts of Maryland and Virginia 2016 ESI BIRDS Polygons, Points

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.
