What Our Participants are Saying:

Outstanding Birding Days!

We spent 2 days with Carl; the first day started at the top of Rocky Mountain National Park and ended at the bottom. The 2nd day was in the foothills. I have never had a birding guide that worked as hard as Carl, from giving advice on finding birds the days before and after our… Read more “Outstanding Birding Days!”

Everything Was Perfect!

Carl is an excellent guide. We did a half day with him, starting in the early a.m. (6:30 a.m.) We started at Sheep Lakes and drove the Trail Road to Medicine Bow Curve and back. Carl knows all the great birding areas in RMNP and was able to help us see and photograph many life… Read more “Everything Was Perfect!”

Awesome as Always!

Carl, Jeff & Christian by Carl Bendorf

Once again, Carl & Christian delivered on a fantastic birding experience; tailored to my targets and to my pace. I like to cover a lot of ground, get to multiple habitats and essentially “big day” bird every day. Whether it is chasing after lifers, getting quality time with a few species, a day trip or… Read more “Awesome as Always!”

Jeff Kietzmann, Florida

I Highly Recommend

I spent 2 days with Christian mainly looking for white-tailed ptarmigan. Christian is a very caring guide. He takes time to get to know the client and will tailor the trip to suit client’s needs. He also knows a lot about plants, other wildlife such as mammals…etc. I highly recommend him. Thank you Christian.

Colorado Birding Weekend

Christian was great company and very professional throughout the weekend. We hit nearly all my target birds in just two days including high altitude and prairie birds. He was knowledgeable, patient, and fun to be with. I would love to go back birding with him again.

Sandra W., Westchester, NY

We had an awesome day!

We had an awesome day with Marcel. Saw over 43 species at 5 different sites. Best guide ever and a joy to be with for the day.

Weekend Birding Trip

I contacted Carl when I had a business trip out to Colorado, which I was able to extend over the weekend. I didn’t have any specific targets, just wanted to hit a few hotspots, but Carl devised an itinerary that still yielded six life birds for me, during a really fun day driving around with… Read more “Weekend Birding Trip”

Carl not only put me on a lot of great birds, he is also very knowledgeable and a lot of fun to bird with. He was professional and made the planning process easy.

A success right from the beginning

I had a private 5 day birding tour with Carl Bendorf of Colorado Birding Adventures in early May 2019. The trip was a success right from the beginning. I hit it off right away with Carl as he is very easy going and has a good sense of humor. We saw a very close White-Tailed… Read more “A success right from the beginning”

Definitely 5 Stars!

I’m finally approaching 700 lifers for North America as are my trip companions, Pam and Ed. We decided to maximize our efficiency by hiring a guide. We’re so glad we picked Carl. Sure, we could have used ebird and hoped we could find the right locations. However, Carl knows the locations, the wildlife (not only… Read more “Definitely 5 Stars!”

A Terrific Experience

We were on a short visit from Ontario, Canada and arranged for a half day of birding with Carl. He was very receptive to my email requests for a specific day and target species. He picked the two of us up promptly at the planned time, and provided extra binoculars, water and snacks. He also… Read more “A Terrific Experience”

Great Birding Adventure

We grownups and grandchildren had fun with Carl. We were in town for a wedding and Carl brought us to Lyon where we walked,talked, phished, and stood in awe. I loved how Carl always made sure to lower the scope so the kids got a grand view of the great Horned Owl, the Golden Eagle,… Read more “Great Birding Adventure”

Outstanding Birding Guides!

Colorado Birding Adventures organized a wonderful “target birding” private tour for me on extremely short notice. My excellent guide, Marcel Such, displayed superb birding skills and up-to-the-second knowledge of Mountain Plover, McCown’s Longspur, Red-naped Sapsucker and Brown-capped Rosy-Finch, all the four life birds I wanted to see plus many other interesting Colorado specialties. I highly… Read more “Outstanding Birding Guides!”

Found Species I Didn’t Even Know About!

I’ve had the pleasure of birding with Colorado Birding Adventures in both winter and summer, and both trips exceeded my expectations! My first trip was in Feb. 2018 with Christian. I had an ambitious “wish list” of species, and he found most of them. This required quite a bit of persistence and expertise; esp. for… Read more “Found Species I Didn’t Even Know About!”

Birding Colorado? Do it right!

I spent a most enjoyable day birding with Carl. Most of our day was spent in Rocky Mountain National Park. The scenery alone was simply breathtaking. I had given Carl a list of five bird species of which I was most interested in seeing. And didn’t Carl nail ALL of them, with STUNNING views. Our… Read more “Birding Colorado? Do it right!”

Some of the Best Birding Days I’ve Ever Experienced

Birding in Colorado was a “Rocky Mountain High” for me! I spent two packed days of birding with Colorado Birding Adventures while my wife was in Denver on a business trip. Those two days were easily some of the best days of birding I’ve ever experienced. Carl Bendorf, lead guide and owner, made it an… Read more “Some of the Best Birding Days I’ve Ever Experienced”

Can’t Recommend Enough!

“I recently had a phenomenal 2.5 days of birding with Carl Bendorf, the owner of Colorado Birding Adventures.

Above and beyond – a thrilling birding experience!

” I was thrilled with how in-tune my guide, Carl Bendorf, was with helping me find the birds I was looking for. In my case, I was trying to see and photograph as many Colorado birds as possible in a few days, and Carl really went above and beyond to help me achieve that goal.

Truly outstanding and memorable… not only an amazing birding adventure, but a special life learning experience!

“We were enthralled by our 5 hours of birding around Rocky Mountain National Park. Several picturesque and strategic stops around the park were highlighted by strolls through wooded and forested trails– home to majestic mammals and spectacular birds. Basic birding skills were employed to highlight the experience. Once a species was spotted, significant time was… Read more “Truly outstanding and memorable… not only an amazing birding adventure, but a special life learning experience!”

Mountain plover and white tailed ptarmigan were highlights

Highly Recommended Without Hesitation

“As Executive Director of Seven Ponds Nature Center in Lapeer County, Michigan, I contacted Carl about six months ago to inquire about his interest in working with a tour group from Michigan for an extended tour in June of 2017.

Marie and Deacon from Colorado

“My son and I went on our very first birding expedition with Carl, who is a knowledgable and experienced guide. He was wonderful with my teenage son, answering all of my son’s questions with patience and wisdom. I wasn’t a natural with the binoculars, so Carl took out the telescope. Wow!

Bighorn Sheep

“Carl is an experienced, knowledgeable, and personable guide! I chose the full-day trip in Rocky Mountain National Park, telling Carl that although finding life-list birds was my main interest, I also wanted to see the spectacular scenery of the park itself.

It Was a Great Experience!

“I had a great time birding in Rocky Mountain National Park with Colorado Birding Adventures. Carl Bendorf was a companion as well as a guide. He knew a lot about the various habitats and the locales of where to find specific species. Admittedly, mid-August isn’t the best time to see large numbers of birds, but… Read more “It Was a Great Experience!”

Smooth and productive Colorado lifer tour!

“Six day tour of grasslands/foothills/mountains, 144 bird species, 13 lifers, oodles of non-bird wildlife, fabulous scenery, great food/lodging, and fantastic leadership. What’s not to like? Heck, we even had perfect weather! Highlights for me in the bird category were white-tailed ptarmigan, long-billed curlew, sage grouse, mt. plover, barn owl, two longspurs and a rosy finch.… Read more “Smooth and productive Colorado lifer tour!”

Awesome Trip…One of our best ever!

“Awesome trip with Carl! My husband and I joined two other couples on a six-day customized tour with him and John Rutenbeck, looking for Colorado specialties. His pretrip research and planning quickly became obvious, and every evening he updated it to give us the best chance of seeing the target birds. Result: we saw 15… Read more “Awesome Trip…One of our best ever!”
