Colorado is a big state and our route will maximize our birding in varied habitats while minimizing our driving time.  North-central Colorado offers birding from the short-grass prairies to the alpine tundra and majesty of Rocky Mountain National Park with the variety of the foothills in between. One of our days will be a long swing down into the cholla cactus and pinyon-juniper areas south of Colorado Springs with a goal of adding even more species to our trip list.  Our final day is flexible to allow us to seek species we may have missed earlier. Besides the great birding, the scenery will be spectacular! 

Our tour headquarters will be Longmont, a thriving city of 100,000 centrally located just 45 minutes from both the mile-high city of Denver and Denver International Airport (DEN). Participants should arrange to meet us at the Fairfield Inn (1089 South Hover Street) in Longmont by 3 p.m. on Day 1. We can provide you with a list of available shuttle services from the airport or from Denver.

Tour at a glance:

Day 1:  Arrival day in Denver/Longmont and afternoon birding in the Foothills

Day 2:  Pawnee National Grasslands

Day 3:  Rocky Mountain National Park

Day 4:  Foray into south-central Colorado

Day 5:  Flexible but likely a return to Rocky Mountain National Park

DAY 1 – If you are arriving by plane on this day, plan to meet us at the Fairfield Inn in Longmont by 3 p.m.  After checking in to your hotel, we’ll head head ½ hour west from our Longmont hotel for our first birding sample of the Foothills–where the vast Great Plains prairie meets the Rocky Mountains.  We may visit several birding hotspots for our first try White-throated Swift, Broad-tailed Hummingbird, Golden Eagle, Western Wood-Pewee, Cordilleran Flycatcher, Violet-green Swallow, American Dipper, Lesser Goldfinch, Spotted Towhee, Bullock’s Oriole, and Lazuli Bunting. After enjoying our first group dinner back in Longmont, we’ll learn more about birding in Colorado and our plans for the rest of our days.  Overnight in Longmont.

Your comfortable lodging for tonight and every night of our tour is the popular Fairfield Inn & Suites Boulder/Longmont, a perfect base of operations for our birding. 

Burrowing Owl at Pawnee Grasslands

DAY 2 – Pawnee National Grasslands.  We’ll Leave Longmont early for the 90 minute drive northeast to the Pawnee National Grasslands.  Described by author/birder Pete Dunne as one of his favorite birding destinations in the world, Pawnee is one of the most intact examples of short-grass prairie in the Great Basin—and an unforgettable experience for any birder.  We will have a quarter million acres nearly to ourselves as we search for the resident breeding species including Swainson’s and Ferruginous Hawk, Burrowing Owl, Says, Phoebe, Western Kingbird, Black-billed Magpie, Chestnut & Thick-billed Longspurs, Cassin’s, Grasshopper, and Brewer’s Sparrows, and Lark Bunting.  We will also see the occasional Common Nighthawk utilizing the only available day-perch in sight–a roadside fence post! After a picnic lunch at Crow Valley Park, we’ll visit several water areas on our way back to Longmont for Cinnamon Teal, Western and Clark’s Grebe, American Avocet, Black-necked Stilt, White-faced Ibis, Yellow-headed Blackbird and Great-tailed Grackle. Dinner and overnight in Longmont. 

DAY 3 – Rocky Mountain National Park.  The fourth most-visited national park (4.4 million visitors in 2021), RMNP offers some of the finest mountain birding in Colorado.  We will enter the park from the east and drive directly to the top of Trail Ridge Road (12,183 feet).  Here we will be well above treeline and in the spectacular alpine tundra home of Brown-capped Rosy-Finch and White-tailed Ptarmigan.  Both are relatively common but can be very difficult to locate. We’ll have plenty of time to enjoy the spectacular scenery amidst the abundant nesting Horned Larks and displaying American Pipits.  

Later in the morning, we’ll work our way back down the east slope of the park through the sub-alpine (10,000-11,500’) and montane (8,000-10,000’) life zones which each have their own distinct mix of birds.  Here we will seek Northern Pygmy-Owl, Williamson’s and Red-naped Sapsuckers, American Three-toed Woodpecker, Hammond’s and Dusky Flycatchers, Canada Jay, Steller’s Jay, Clark’s Nutcracker, Mountain Chickadee, Mountain Bluebird, Townsend’s Solitaire, Pine Grosbeak, Cassin’s Finch, Red Crossbill, Green-tailed Towhee, Virginia’s and MacGillivray’s Warbler, Western Tanager, and Black-headed Grosbeak.  And we haven’t yet mentioned some of the mammals we might find such as elk, mule deer, bighorn sheep, moose, yellow-bellied marmot, American pika, golden-mantled ground squirrel, and least chipmunk. Dinner and overnight in Longmont.

DAY 4 –  Marathon foray into Southern Colorado. This will be our longest driving day as we venture down into southern Colorado for new habitats and new birds.  Just south of Colorado Springs, we will explore vast areas of cholla cactus which can harbor Chihuahuan Ravens, Curve-billed Thrashers, and Scaled Quail.  In the afternoon, we’ll explore the beautiful Arkansas River Valley in search of Pinyon Jay and Lewis’s Woodpecker before returning to Longmont for dinner and overnight.

DAY 5 – Flexible Itinerary.  We’ll use our last day to look for species we may have previously missed. This may include a return to the spectacular Rocky Mountain NP, checking various lakes and reservoirs, or even just a thorough exploration of Boulder County. After a final group dinner, our tour will conclude at the Fairfield Inn around 7 p.m.

Note: Your lodging on the last night of June 15 is NOT included in your registration fee giving you the option to book another night on your own at the Fairfield Inn or another location of your choosing near the airport.

We will focus on the target species that most visiting birders want to find—how many of these have YOU seen?

No guarantees, of course, but we’ll try to see as many of these prairie and mountain west species as possible in five days!!  Join our small group of like-minded fellow birders as we fill in those holes on your life or year list. This tour will truly be a summer birding bonanza!

Please review the following carefully to make sure this tour is a good fit for you:

COVID-19:  Our current policy is that all tour participants and leaders will be required to have completed the full course of their CDC-recommended COVID-19 vaccine at least two weeks prior to the start of the tour. Proof of vaccination must be provided to us (by emailing a photo or scan of your vaccination card) before departure. This policy is subject to updating depending on changing public health conditions, CDC and/or State of Colorado recommendations, other other factors beyond our control.

Please be aware that some travel insurance policies may not cover COVID-19-related illnesses or expenses. If a participant is unable to continue with their tour due to a COVID-related reason, all costs associated with isolating and/or later rejoining the tour are the participant’s responsibility.

Non-smoking: Smoking is not permitted during any of our group activities including van travel, group birding, or meals. The block of rooms we have reserved are all non-smoking rooms.

Altitude, Mobility, and Stamina:  Participants should be aware of the potential effects of altitude and take steps to prepare including proper hydration.  Colorado has the highest average elevation in the United States and our birding and travel will range from roughly 4,500 feet above sea level to several brief periods about 11,000 feet.  Our four overnights will be in Longmont (elevation 4,984 feet above sea level.)  Our days will be active and can include multiple walks of up to one mile on level roads or on trails with some rocky sections.  Most walks are filled with frequent pauses to observe birds.  This tour is not recommended for birders who are prone to altitude-related health issues,  have mobility issues, or who have difficulty or are unwilling to climb unassisted in and out of mini-vans.   We recommend that you consult with your physician prior to committing to this trip and if you have health conditions or concerns about your ability to undertake moderate activity at higher elevations.

Daily Schedule:  For optimal birding, we will start early each morning with at least one morning departure from the hotel at 4:30 a.m.   Our first day of birding begins in the mid-afternoon and will continue until about 6:30 p.m. followed by dinner. In mid-June, sunrise is approximately 5:30 a.m. and sunset is 8:30 p.m.  Our daily schedule will vary and is subject to change. A more detailed schedule will be provided to participants.  We will travel in two regular size mini-vans; participants should be prepared to ride in any seat and switch seat locations each day.  Depending on the number of participants, space for items such as heavy-duty tripods and large backpacks may be limited each day.  We encourage you to travel light.

Weather/Clothing:  Weather conditions in Colorado in June can vary widely. Average June temperatures in Denver/Longmont are highs in the lower 80sF and lows around 50F, but we will have at least one early morning at higher elevations in Rocky Mountain National Park where it can be quite cold and windy even in summer; a warm hat/gloves/coat may be needed. In contrast, the temperatures at the Pawnee Grassland can easily be well into the 90s! Afternoon thunderstorms are also common anywhere.  Be prepared with layers of clothing that can adapt to chilly mornings and hot, sunny afternoons. We will not be hiking in extreme rocky places and lightweight hiking boots or sturdy walking shoes will be sufficient.  A windbreaker/rain jacket is recommended as well as a hat for sun protection.  A suggested packing list will be provided to participants.

Based on the above description of the physical requirements of the tour, if you are concerned about whether this tour is a good fit for you please contact us and fully explain your concerns before you register and make a deposit.  To ensure a quality experience for all participants, we may be limited in our ability to make special accommodations if you have mobility, stamina, or altitude-related limitations.
