Colorado Parks & Wildlife - Species Data - Bald Eagle Winter Forage

Colorado Parks and Wildlife
BaldEagleWinterForage is an ESRI SDE Feature Class showing winter foraging areas for Bald Eagles (Haliaeetus leucocephalus) in Colorado. Winter Foraging Areas are defined as areas frequented by wintering bald eagles between November 15 and March 15. These may be large areas radiating from preferred roosting 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).
