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.
