This dataset shows colonial nesting waterbirds in coastal North Carolina. It is a subset from North Carolina's online colonial-nesting waterbird database (http://ncpaws.org/). The data included years 2006-2010, all available species, and was spatially selected to include nests within 5 miles of the coast
This GIS dataset was created for the purpose of describing the location and types of colonial waterbirds that nest along the North Carolina coastline so that these nesting activities can be considered for any planned energy development or other coastal use activities.

1.) Database export: All counties, years 2006-2010, all species, and all sites were selected. 2.) Spatial selection: The data was clipped to a 5 mile inland buffer of the NC coast. All data further inland were excluded. 4.) All metrics were computed in MS Access from source data provided. 5.)The number of unique surveys at a given site were computed using two sequential queries. In the first query, the number of unique visit dates was computed with respect to each location (group by) by calculating the number of different species seen (count) on a given visit date (group by). In the second query, the number of different survey dates (count) for each location (group by) was computed. 6.)Using a Cross Table Query with the following input information (row = location; column = species; cell value = sum), the total number of nests for each species (over the entire study period) was computed. 7.)The number of different species seen nesting at a given location over the entire study period was computed as the count of all nest counts >0 for a given location; thus, if a location reported one nesting species, all column values would be zero except the one species with nests. 8.) Exported out of Access and brought into ArcGIS as a point feature class.
