Description:
BaldEagleWinterConcentration is an ESRI SDE Feature Class showing winter concentration areas for Bald Eagle (Haliaeetus leucocephalus) in Colorado. Winter Concentration Areas are defined as areas (trees, islands, etc.) within an existing winter range where eagles concentrate between November 15 and April 1. These areas may be associated with roost sites. 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).
