Colorado Parks & Wildlife - Species Data - Bald Eagle Roost Sites

Colorado Parks and Wildlife
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).
