BaldEagleRoostSites is an ESRI SDE Feature Class showing a 0.25 mile
buffer zone around Bald Eagle (Haliaeetus leucocephalus) roost sites in
Colorado. Roost sites are defined as groups of or individual trees that
provide diurnal and/or nocturnal perches for less than 15 wintering bald
eagles; these trees are usually the tallest available trees in the
wintering area and are primarily located in riparian habitats.
This information was derived from field personnel. A variety of data
capture techniques were used including drawing on mylar overlays at
1:50,000 scale USGS county mapsheets and implementation of the
SmartBoard Interactive Whiteboard using stand-up, real-time digitizing
at various scales (Cowardin, M., M. Flenner. March 2003. Maximizing
Mapping Resources. GeoWorld 16(3):32-35).
Dataset was acquired from a third party distributor who obtained it from CDOW in January 2011. The authoritative data source is available on ArcGIS.com (http://www.arcgis.com/home/item.html?id=30cc9afded9c44d8835141f98f0c485a) and will be updated from that location.
