Checklist: Larimer County Checklist
Introduction: Larimer County is one of the largest counties of Colorado, and extremely varied in ecosystems, with high Rocky Mountain peaks, rivers, foothills, prairie grasslands and rich agricultural areas (map). The southeastern corner is populated by the growing cities of Fort Collins and Loveland, and this large human development provides an unnatural but attractive ecosystem to many species of birds. The reservoirs created to provide drinking and irrigation water also attract a great variety of birds, including many rarities. Most visiting birders will associate Larimer County with Rocky Mountain National Park.
