ITINERARY
Day 1: Arrival in Denver. Arrive at Denver International Airport (DEN), orientation and welcome dinner. Optional birding nearby. Overnight: Hampton Inn and Suites Airport-Gateway Park, Denver.
Day 2: Loveland Pass and Silverthorne to Gunnison. We depart Denver and drive toward Gunnison, making several stops along the way. Loveland Pass, about one hour west of Denver, is primarily known for its sweeping views of the Continental Divide and mountain peaks - a popular destination for scenic drives. Loveland Pass offers rare access to alpine tundra habitat without a strenuous hike, making it a top spot for high-mountain species. In early April, snow may still blanket the landscape, concentrating birds in visible areas and offering a chance to see species that are otherwise elusive in the summer. This is a reliable place to find White-tailed Ptarmigan – the crown jewel of Loveland Pass birding. These cryptic, snow-white birds blend into the tundra but can often be spotted near the trail west of the summit parking lot or in the southeastern bowl. Silverthorne, also along I-70, is a great place for birding. April brings a mix of lingering winter species and the first wave of spring migrants, offering a dynamic birding experience. Notable species found in these areas include Rosy-Finches (Brown-capped, Gray-crowned, and Black), Horned Lark, Mountain Bluebird, Mountain Chickadee, Evening and Pine Grosbeaks, Pygmy Nuthatch, Dark-eyed Junco, Cassin’s Finch, Canada Goose, and Osprey. Overnight: Holiday Inn Express, Gunnison.
Day 3: Gunnison to Montrose. Our goal this morning is to look for the endemic Gunnison Sage-Grouse display on its lek. This bird is one of North America’s rarest and most localized bird species, found almost exclusively in the Gunnison Basin. Beyond the lek, Gunnison offers diverse habitats from sagebrush flats to montane forests and canyonlands. After the morning display by the sage-grouse, we will have an opportunity for additional birding throughout the day as we drive west toward Montrose visiting several locations and waterways along the way. Other potential sightings in this area include American Dipper, Common and Barrow’s Goldeneyes, Black-billed Magpie, Brown-capped Rosy-Finch, (and Black and Gray-crowned), Evening Grosbeak, Prairie Falcon, Golden Eagle, and Rough-legged Hawk - among many others. Overnight: Hampton Inn, Montrose.
Day 4: Gunnison Basin and Black Canyon to Grand Junction. Montrose offers exceptional birding, with access to riparian corridors, wetlands, and canyon habitats. It is a strategic base for continuing to explore the Gunnison Basin and Black Canyon. Today we visit Black Canyon of the Gunnison National Park where Dusky Grouse is possible. Black Canyon’s steep cliffs, pinyon-juniper woodlands, Gambel oak uplands, and riparian zones along the Gunnison River create a mosaic of habitats that support a wide range of birds. In April, the park comes alive with breeding activity, early migrants, and resident species. Other notable species found here include White-throated Swift, American Dipper, Canyon Wren, Steller’s Jay, Slate-colored Fox Sparrow, Woodhouse’s Scrub Jay, Spotted Towhee, Clark’s Nutcracker, Townsend’s Solitaire, Violet-green Swallow, Peregrine Falcon, Hairy Woodpecker, Plumbeous Vireo, Western Tanager, and Northern Pygmy-Owl. Overnight: Holiday Inn Express, Grand Junction.
Day 5: Grand Junction to Craig. Located at the confluence of the Colorado and Gunnison Rivers, Grand Junction sits at the ecological crossroads of high desert, riverine woodland, and mesa country. April brings a surge of activity: wintering birds linger, early migrants arrive, and breeding residents become vocal and visible. In the morning, we will explore the canyonlands of Colorado National Monument searching for Pinyon Jays, Juniper Titmouse and Black-throated Sparrows. The predominant pinyon-juniper woodland throughout this region offers critical habitat for a diverse array of bird species. This region also encompasses the habitat where the Chukar, an introduced species from Eurasia, can be found. Other notable species found in this area include Western Bluebird, Bushtit, Black-headed Grosbeak, Lesser Goldfinch, Red-tailed Hawk, Gambel’s Quail, Mountain Bluebird, Say’s Phoebe, Canyon, Rock and Bewick’s Wrens, Black-throated Gray Warbler, and Woodhouse’s Scrub-Jay among many others. Overnight: Best Western Plus Deer Park Hotel & Suites, Craig.
Day 6: Craig to Walden. Located in Moffat County in northwestern Colorado, Craig sits at the heart of sagebrush steppe, cottonwood river bottoms, and canyon country, making it one of the best places in the state to observe Sharp-tailed Grouse during their peak lekking season. These areas host active leks where males perform their spectacular breeding displays at dawn. Along the way to Walden, we will search a few spruce forest areas for American Three-toed Woodpecker, Pine Grosbeak and Clark’s Nutcracker before continuing towards Walden. After crossing Rabbit Ears Pass, we’ll descend into North Park - here we may find Sage Thrasher, Mountain Bluebird, Sandhill Crane, Northern Pintail, Redhead, Common Merganser, Mallard, and raptors such as Bald Eagle, Golden Eagle, Rough-legged and Swainson’s Hawks, and Prairie Falcon. Overnight: North Park Inn and Suites, Walden.
Day 7: Walden to Fort Collins. Located in North Park, a high-elevation basin surrounded by mountains, Walden sits at the heart of Colorado’s sagebrush steppe and wetland ecosystems and one of the best places to find Greater Sage-Grouse in Colorado. We continue driving to Fort Collins after we have watched the Greater Sage-Grouse on their lek – exploring several locations along the way. We will stop at Walden Reservoir State Wildlife Area, where there is a possibility of seeing fifteen species of ducks. We’ll also search for other species in the foothills, including Sandhill Cranes, Green-tailed and Spotted Towhees, Vesper Sparrows, and various raptors. Cameron Pass will provide a final opportunity to observe any remaining boreal forest bird species, including Pine Grosbeak, Cassin’s Finch, Canada Jay, and American Three-toed Woodpecker. As we proceed down Poudre Canyon toward Fort Collins, the route features impressive landscapes along the Poudre River, where American Dipper can be found and Common Merganser are known to nest. Overnight: Holiday Inn Express, Fort Collins.
Day 8: Fort Collins to Wray. Fort Collins offers excellent Front Range foothill birding with diverse habitats from riparian corridors to ponderosa pine foothills. Pineridge Natural Area, Fossil Creek Reservoir Natural Area, Arapahoe Bend Natural Area, and Pawnee National Grasslands are noted as some of the best locations for birding in the area. Notable species found in the area include Townsend’s Solitaire, Pygmy Nuthatch, Mountain Chickadee, Spotted Towhee, Mountain Bluebird, Canyon Towhee, Rock Wren, Mountain Plover, and Juniper Titmouse (uncommon but possible). We then start heading east to the Pawnee National Grasslands, where we will be looking for Ferruginous and Swainson’s Hawks among the fields, along with Mountain Plover, Chestnut-collared and Thick-billed Longspurs. Overnight: Cobblestone Inn and Suites, Wray.
Day 9: Wray to Scott City, Kansas. Wray is one of the best places in the state to see Greater Prairie-Chickens. Wray sits in the heart of Colorado’s eastern plains, surrounded by sandsage prairie and mixed-grass habitat – the preferred breeding grounds of the Greater Prairie-Chicken. We will most likely hear the Greater Prairie-Chickens before we can see them. Each spring, males gather at dawn on leks to perform booming displays, inflating bright orange neck sacs, stomping their feet, and raising feather plumes in a ritual that has captivated birders for generations. Other notable species in the area include Northern Bobwhite, Wild Turkey, Eastern Bluebird, Red-bellied Woodpecker, Mississippi Kite, Northern Shoveler, Green-winged Teal, Ruddy Duck, and Lark Bunting to name a few. We will then drive southeast, birding our way into Kansas in search of the Lesser Prairie-Chicken. Overnight: Best Western El Quartelejo Inn and Suites, Scott City.
Day 10: Scott City, Kansas to Pueblo, Colorado. Early morning will find us on a Lesser Prairie-Chicken lek. Located in western Kansas, Scott City sits at the intersection of shortgrass prairie, playa lakes, and canyon country, making it a diverse and rewarding birding location. April is peak season for Lesser Prairie-Chicken lekking, and nearby reservoirs and state parks host a mix of migrants and breeding residents. In the afternoon, we start making our way to Pueblo, searching along the way for any missing prairie birds like Mountain Plover, Burrowing Owl, and Longspurs. Overnight: Holiday Inn Express & Suites, Pueblo North.
Day 11: Tour Conclusion & Departures. On our final morning, we explore Pueblo Reservoir. The reservoir’s location where mountains meet plains creates habitat diversity supporting both groups’ species. The Arkansas River flowing into the reservoir provides riparian habitat attracting migrants and breeding birds. Surrounding grasslands and rock outcrops add additional habitat types. The reservoir excels during migration when waterfowl and shorebirds concentrate on mudflats and open water. Rarities also appear regularly, making Pueblo Reservoir a favorite among Colorado’s serious birders. Participants may make arrangements to leave Denver after 2 p.m. today.
