Colorado Parks & Wildlife - Species Data - Bald Eagle Summer Forage
Colorado Parks and Wildlife Biologists, District Wildlife Managers, and Researchers
BaldEagleSummerForage is an ESRI SDE Feature Class showing summer foraging areas for Bald Eagles (Haliaeetus leucocephalus) in Colorado. Summer Foraging Areas are defined as those areas frequented by breeding bald eagles from March 15 to July 31. These areas are almost always associated with nesting pairs. 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).
