Colorado combines spectacular scenery and a variety of habitats with the largest diversity of native grouse and quail species found anywhere in North America. Our journey takes us from the eastern prairies, which are home to Greater and the endangered Lesser Prairie-Chickens, to the western sagebrush plains which harbor one of the last remaining populations of the critically endangered Gunnison Sage-Grouse and the equally stunning but more numerous Greater Sage-Grouse. In between, we visit the foothills east and west of the Rocky Mountains to look for Scaled and Gambel’s Quails, Sharp-tailed and Dusky Grouse, and the introduced Chukar. We also venture to the high elevations above the tree-line to search for the difficult White-tailed Ptarmigan, still in its immaculate alabaster plumage during this time of year. In addition to the “chickens”, the prairies hold Mountain Plover, Thick-billed and beautiful Chestnut-collared Longspurs, while the foothills and higher elevations harbor a wide variety of Rocky Mountain specialties. The pine forests at middle elevations are home to such sought-after species as Pinyon and Woodhouse’s Scrub-Jays, Clark’s Nutcracker, Lewis’s Woodpecker, Williamson’s Sapsucker, Juniper Titmouse, and American Dipper. Boreal forests at higher elevations support American Three-toed Woodpecker, Steller’s and Canada Jays, Mountain Chickadee, and Pygmy Nuthatch. Feeders can attract an incredible array of winter finches with Gray-crowned, Black, and Brown-capped Rosy-Finches often present in large mixed flocks, while Evening and Pine Grosbeaks, Cassin’s Finches, and Red Crossbills add to the diversity. Other highlights we will search for in the sagebrush habitats include Sage Thrasher, and Sagebrush and Brewer’s Sparrows. Lakes and reservoirs along the way will offer a wide selection of waterfowl with around 20 species possible, including Barrow’s Goldeneye, and these bodies of water also harbor Clark’s and Western Grebes. The open landscapes and rocky cliffs are excellent for raptors and we can expect to see a dozen species. This tour is also superb for mammals with two dozen species possible, ranging from the massive Moose to the diminutive Least Chipmunk to round out one of the finest birding adventures in North America. Photographic opportunities of birds, other wildlife, and scenery are exceptional on this tour.
