BaldEagleWinterRange is an ESRI SDE Feature Class showing winter range for Bald Eagles (Haliaeetus luecocephalus) in Colorado. Winter Range is defined as those areas where bald eagles have been observed between November 15 and April 1. 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).
