Unlike many other northern states, many bird species choose to overwinter in Colorado rather than flying south. Many birds migrate south from Colorado for winter to warmer climes, such as warblers, sparrows, hummingbirds, and wrens,
However, winter is still a fantastic time to go birding in Colorado as a bounty of ducks and geese arrive to spend the winter, plus some birds of prey that are great to spot. Don’t forget about all the hardy birds that remain all year and brighten up the cold dark months.
Colorado is also on one of the great flyways of North America and millions of birds will fly along this route in early spring and late autumn to their breeding or wintering grounds.
This guide will give you an overview of birding in Colorado in winter and show you highlight birds of winter in Colorado that you should try to see at this time of year. Also, the 25 most common birds that are spotted here in winter, with photos and ID guides and calls to help you identify them. Plus much more.

Must See Winter Birds Colorado
Introduction To Birding In Colorado In Winter
Some birding locations, like Snow Goose Trail near Burlington on the Southeastern Plains of the state, boast a beautiful and picturesque selection of geese, like Snow Geese and Ross’s Geese, which overwinter on waterways. There is even a Snow Goose festival in February to celebrate this spectacle.
A trip to the open tundra of the Rocky Mountain National Park in mid-winter isn’t for everyone, but it is the ideal time to see one of nature’s special wonders. The White-tailed Ptarmigan, which was perfectly camouflaged brown in the summer months, develops splendid, almost magical-looking white plumage for the winter season.
Familiar visitors at Colorado birdfeeders during the winter months are American goldfinches. These lively little birds can occur throughout the year but are more likely to appear in winter. Interestingly, the brilliant bright plumage that they sport during warmer months becomes dull during the cooler months.
Another winter visitor to feeders around the Colorado Springs area are Dark-Eyed Juncos. These small seed eaters tend to stay low to the ground and may be found cleaning up seeds that have fallen around feeders.
Anyone exploring Barr Lake State Park in winter should look out for Bald Eagles, which are commonly sighted in the area, especially during the winter months. These large predators are always exciting to observe as they continuously scan their environment for prey. Rough-legged Hawks are other birds of prey that spend winter in Colorado.
Crows have a following all of their own among birders, and winter is an excellent time to spot impressive ‘murders’ of American Crows. These noisy characters are commonly seen around the Colorado Springs area during the cold months and liven up the landscape with their familiar ‘caw’ sounds.
Some birds move to lower elevations in winter in Colorado, rather than flying south, such as Prairie Falcons, Townsend’s Solitaires, and young Mountain Chickadees.

Dark-eyed Junco Song:
Attract Dark-eyed Juncos to backyard feeders with a variety of seeds such as black oil sunflower seeds, nyjer, cracked corn, millet, and peanuts. Platform feeders or scattered on the ground are best.

House Finch Song:
House Finch Call:
Attract House Finches to backyard feeders with black oil sunflower seeds or nyjer seeds in tube feeders or platform feeders.

5. Canada Goose
The Canada Goose, also called the Canadian goose, is a large, long-necked goose recognized for its black head and easily identifiable white chin strap.

You can find Canada Geese practically anywhere. They are often seen near lakes and rivers, basically, anywhere there’s a body of water and an abundant food source. They are also used to humans, so they live comfortably in urban habitats like city parks, reservoirs, golf courses, public parks, and beaches.
In some places, their population has risen considerably and they’re considered pests.
Canada Geese mainly eat grasses when they’re on land and small aquatic insects and fish when they’re on the water. They also eat wheat, rice, and corn when they’re on agricultural fields. They’re accustomed to receiving food from humans or digging through trash cans.

How Do Birds Survive Winter
Birds that stay for winter are amazingly adapted to surviving winter by using these tricks to stay warm
- Move to lower elevations
- Fatten up to stay warm
- Go into torpor at night, which is where the birds lower their body temperature, almost like hibernating.
- Molt into a warmer winter coat and puff it up to trap air
- Huddle up with other birds so share body heat
- Change their diet and eat high-fat food such as black oil sunflower seeds
- Cache food in the autumn and raid these stores when needed over the winter
