Colorado is the best place in the country for finding all the species of Prairie-chicken and many if the Grouse. Its varied topography, ranging from prairie grasslands through high plains to subalpine forests and alpine tundra, supports as many as 500 species of birds; its geographical location astride the Continental Divide provides a mix of eastern, western, northern, and southwestern species not easily found together anywhere else.
Our trip will take us from the eastern prairies of Colorado into the high Rocky Mountains, covering about 2000 miles in searching for our target species. In order to see many of these species at their leks at dawn, we’ll need to be up and out by 4:00 or 4:30 AM. We expect to find Greater and Lesser Prairie-Chicken; Greater and Gunnison’s Sage-Grouse; Sharp-tailed and Dusky Grouse and, possibly, White-tailed Ptarmigan. Other species of interest include Mountain Plover; Three-toed Woodpecker and Williamson’s Sapsucker; Rough-legged Hawk; Black, Brown-capped, and Gray-crowned Rosy-Finch; McCown’s and Chestnut-Collared Longspur, and many others.
