Living or visiting Colorado and wondering what bird you’re looking at? This article covers the most common birds of Colorado. Odds are high the bird you’re looking at is one of them. It will also inform you on how to identify them.
Colorado is among the top ten best states for birding. Five specific locations are special favorites among birders.
- Barr Lake in Adams County is where the Rocky Mountain Bird Observatory, as well as 350 different species of birds, can be found.
- The Cherry Creek Reservoir in Arapahoe County is a prime Colorado birding site from summer through spring throughout the winter. The southern part of the lake is home to shorebirds. During the summer, the reservoir is where the Yellow-breasted Chat and the Yellow Warbler come to breed.
- Birders come to the Monte Vista National Wildlife Refuge in Rio Grande County for the Sandhill Crane migration during the spring and fall. There is a crane festival every March as well as tours through San Luis Valley.
- Huerfano County has more than a hundred species of birds, and the spring months of April through June are the time for spotting them. The town of La Veta is a great place for finding bald eagles during the winter, turkey vultures, ravens, hummingbirds, downy woodpeckers, and great-horned owls.
- Crow Valley Campground in Weld County has trees and water and is a popular migrating bird destination. The campground can fill with warblers, Common Redpoll, thrushes, and flycatchers. In the winter, the Long-eared owls may come to roost. There are excellent birding trails in the southern part of the campground. The northern trails may lead to the White-faced Ibis and other wading birds.
Colorado’s Most Common Birds
The Lark Bunting is Colorado’s state bird and an excellent representative of this beautiful state. This sparrow has a compact body and a large, conical bill. It grows 5.5 to 7.1 inches in length, weighs 1.3 to 1.5 ounces with a wingspan of 9.8 to 11.0 inches.
This regal-looking bird is black with elegant white patches on its wings and has a light blue bill. The female is more brownish, with brown belly streaks. They forage for food on open ground and grassland and feed on insects and seeds.
Brown-capped Rosy Finch
The Brown-capped Rosy Finch lives mostly in the Rockies, especially in Colorado.
This is a small songbird with a long and forked tail and a short, conical dark bill that turns yellow during the non-breeding season. They grow between. 5.5 to 6.3 inches in length, weigh 0.8 to 1.2 ounces with a wingspan of 13 inches.
The male has brown plumage with a gray cap and a noticeable pink underbelly and rump. The female is a duller shade of brown. The Brown-capped Rosy Finch feeds on seed and insects snapped out of the snow.
The Belted Kingfisher is a stocky bird with a short, square tail. The head is large with a shaggy crest, giving them a kind of unkempt “bed-hair” appearance. They grow between 11.0 and 13.8 inches, weigh between 4.9 and 6.0 ounces with a wingspan between 18.l9 and 22.8. Their top is bluish-gray with white marks on the wings and underbelly and around the throat. A rarity in the aviary world, the female is more colorful, with a rust-colored patch around the belly that the male lacks.
They spend their time near streams, rivers, and lakes in search of fish and crustaceans to catch. Their diet also includes berries and small mammals. They nest close to the water and can be found in Colorado year-round.
The Black-capped Chickadee are small birds with short, thin bills. Their head and bib are black, with white cheeks and white and dark-gray striped wings. The underbelly is solid white. They grow between 4.5 and 5.5 in length and weigh between 0.3 and 0.4 ounces. In Colorado, they can be found at an altitude of 5,000 and 9,000 feet in deciduous forests and some urban areas.
They feed mainly on insects in the summer and forage for seeds and berries in the winter. They will visit bird feeders for sunflower seeds, peanut butter, suet, and mealworms.
In Colorado, the majestic Golden Eagle can be found year-round in Mueller State Park, Lake Pueblo State Park, and Cheyenne Mountain State Pak, as well as the Colorado Springs area. They grow between 27.6 and 33.1 inches, weigh between 105.8 and 216.1 ounces with a wingspan of 72.8 and 86.6 inches. Surprisingly, the female is larger than the male. The body is brown, with a golden neck from which it gets its name. Their beak has a dramatic hook that is golden near the face.
They nest in tall trees and steep slopes. Their wide wingspan allows them to soar like few other birds, reaching speeds of 200 miles per hour. They pursue their prey and can spot a mouse’s whiskers from a distance of two miles. They will pursue deer, squirrels, coyotes, livestock, and rabbits. Birders who catch a Golden Eagle in flight are fortunate, indeed.
