What Our Clients Are Saying…


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 birds and mammals, such as Marmots and Least Chipmunks. The highlight of our trip was seeing two female Dusky Grouse that crossed Trail Ridge Rd. near the Endovalley turn off. Carl also knows when to instruct about birds and wildlife, and when to be quiet so his clients can just enjoy the beauty of Rocky Mt. National Park on their own. Highly recommended for local knowledge, ability to find birds and wildlife and personable and friendly guiding. Everything was perfect and as we expected.

I loved spending those two days with Carl, especially that very special moment between him, myself, and a Northern Pygmy Owl, which was my highest target bird on my list for the trip. The time with Carl solidified a birding philosophy of mine, that it’s not “just” about the birds, it’s also about the birding friendships developed along the way.
If you’re looking for experienced, expert, and personal birding…I HIGHLY RECOMMEND… Carl Bendorf and Colorado Birding Adventures.”

Some highlights include superb photos of Black-billed Magpie, Steller’s Jay, Canada Jay, Brown-capped Rosy-Finch, Prairie Falcon, American Three-toed Woodpecker, Pygmy Nuthatch, American Dipper, Townsend’s Solitaire, and of course the extremely elusive White-tailed Ptarmigan! The ptarmigan was by far the most exciting. We spent several hours well above 12,000 feet looking and were finally rewarded with amazing and close views. I took more than 10,000 images in our time together and am just now going through them.
On a personal note, Carl is the quintessential gentleman. Not only is he knowledgeable, he has a tremendously amiable personality that no doubt allowed him to thrive in his previous life as a development officer at a major university. It was an absolute pleasure getting to know him in our short time together. I have no doubt I will be taking advantage of his services again in the near future. I cannot recommend him enough for anyone wanting to see the amazing birds of Colorado.”
