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.

    Aliases - Trail Ridge Road (Larimer section), Medicine Bow Curve, Alpine Visitor Center, Endovalley, Bear Lake
    Description - An entire book has been written to describe birding locations within this beautiful, majestic National Park (Roederer 2002). White-tailed Ptarmigan can usually be found in summer in tundra along Trail Ridge Road near Medicine Bow Curve. In summer, Brown-capped Rosy-Finches sometimes frequent the Alpine Visitor Center (look for these elusive birds near the edges of permanent glaciers). In sub-alpine forest, watch for Dusky Grouse. Endovalley is an excellent location for spruce-fir species. Red-naped and Williamson's Sapsuckers prefer lower elevations in Ponderosa Pine forest with good stands of older Quaking Aspen, which provide nest sites. These nest holes may also serve Northern Pygmy-Owl, Northern Saw-Whet and Flammulated Owls (Rashid, 2005). Three-toed Woodpeckers may be found anywhere with dead trees. Picnic areas throughout the park attract corvids including Gray Jays and Clark's Nutcrackers. Black Swifts and Band-tailed Pigeons can be seen high over Bear Lake.
