Colorado Parks & Wildlife - Species Data - Peregrine Falcon Nesting Area
Colorado Parks and Wildlife Biologists, District Wildlife Managers, and Researchers
PeregrineNestingArea is an ESRI SDE Feature Class showing Nesting Areas for Peregrine Falcons in Colorado. Nesting Area is defined as an area which includes good nesting sites and contains one or more active or inactive nest locations. The boundaries are drawn based on professional judgment to include most known nesting habitat in the vicinity. Usually these areas are mapped as polygons around cliffs and include a 0.5 mile buffer surrounding the cliffs. 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).
