Colorado Parks and Wildlife Biologists, District Wildlife Managers, and Researchers
WhPelicanForagingArea is an ESRI SDE Feature Class showing Foraging Areas for White Pelican (Pelecanus erythrorhyncos) in Colorado. Foraging Areas are defined as those bodies of water used by a minimum of 15 birds on four days out of seven from April 15 through August 15. 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).
