Updated December, 2025 BREEDING RANGE: The area which encompasses the geographic area in which a population of birds can typically be found breeding (the period of time during each year when a species reproduces - mates and has young) in Colorado. OVERALL RANGE: The area which encompasses the observed range of a population of birds. MIGRATION RANGE: The area which encompasses the geographic area in which a population of birds can typically be found while seasonally moving between their winter range and their breeding range. This information was derived from Colorado Parks and Wildlife species experts. A variety of data capture techniques were used including 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). Various sources were referenced in developing these data including CPW Scientific Collection data, Cornell Lab of Ornithology eBird data, and Colorado Breeding Bird Atlas data.
