Winter transforms Colorado’s landscape into a haven for various birds of prey. During this season, many species can be seen soaring through the crisp air or perched on trees and fences, searching for their next meal.
Birdwatchers and nature enthusiasts can expect to encounter several distinctive birds that thrive in the winter conditions, showcasing their impressive hunting skills.
Among the raptors, certain species stand out due to their migratory patterns and adaptability to colder climates. The presence of these birds offers a unique opportunity to observe their behaviors and interactions in a winter setting.
Whether one is exploring the foothills or navigating open fields, the sight of these magnificent creatures adds a sense of excitement to any outdoor adventure.
1) Bald Eagle
The Bald Eagle is a striking bird of prey found throughout Colorado, especially during the winter months. Adults are easily recognized by their white head and tail feathers, contrasting with their dark brown body.
These eagles typically weigh between 10 to 14 pounds, with a wingspan that can reach up to 7.5 feet. Their keen eyesight allows them to spot prey from great distances.
Winter brings opportunities to observe these majestic birds, particularly near bodies of water where they hunt for fish. St. Vrain State Park is one of the best locations for spotting Bald Eagles as they soar gracefully above the landscape. Their distinct call and impressive flight make them a highlight for birdwatchers.

The Red-tailed Hawk is one of the most recognizable birds of prey in Colorado. With a length ranging from 18 to 26 inches and a wingspan of 43 to 55 inches, it is a prominent sight in the winter landscape.
Their distinctive red tail is particularly noticeable, especially when they are soaring above open fields. These hawks often perch on fence posts and trees, scanning their surroundings for potential prey.
Red-tailed Hawks primarily hunt small mammals, including rabbits and rodents. They are adept at using their sharp eyesight to spot movement from great distances.
During the winter months, these hawks can be seen migrating to lower elevations, making them more accessible for bird watchers in Colorado. Their adaptability to various habitats also contributes to their prevalence in the area.
3) Rough-legged Buzzard
The Rough-legged Buzzard, known scientifically as Buteo lagopus, is a striking bird of prey commonly seen in Colorado during the winter months. This medium-large raptor is easily identifiable by its unique plumage, which exhibits both light and dark morphs.
Typically, these birds migrate from their breeding grounds in the Arctic and Subarctic to find milder climates. As the winter approaches, they can often be spotted soaring over open fields and low hills, searching for small mammals.
Nests are usually built on cliff ledges or rocky outcrops, constructed from twigs and soft materials. The female primarily incubates the eggs, which usually number between three to five.
With a wingspan that ranges from 4 to 4.7 feet, they display impressive aerial skills. Watching a Rough-legged Buzzard gracefully glide through the sky can be a captivating experience for birdwatchers and nature enthusiasts alike.
4) Golden Eagle
The Golden Eagle is one of Colorado’s most magnificent birds of prey. It can be spotted year-round, but winter provides excellent viewing opportunities as they hunt for food.
These eagles are large, with adults measuring up to 33 inches in length and boasting a wingspan of nearly seven feet. Their dark brown plumage, with lighter flight feathers, makes them striking in the sky.
Golden Eagles primarily hunt small mammals, such as rabbits and ground squirrels. They are agile fliers, capable of reaching speeds over 150 miles per hour during a dive.
Nesting sites are often found on cliffs or tall trees, where they raise their young in a secure environment. Observing a Golden Eagle soaring effortlessly overhead is a memorable experience for birdwatchers in Colorado.
5) Northern Harrier
The Northern Harrier is a distinctive bird of prey often spotted in Colorado during winter. Known for its slender body and long tail, it glides low over marshes and grasslands, searching for small mammals.
Males are primarily gray with white patches at the tail base, while females are larger and brown, making them easy to identify. Their unique flying style includes holding wings in a V-shape, which adds to their elegance in the air.
With an owlish face, this raptor has exceptional hearing, allowing it to detect prey concealed within vegetation. Some Northern Harriers remain in Colorado year-round, contributing to the state’s vibrant winter wildlife scene.
Understanding Birds of Prey
Birds of prey, often referred to as raptors, have unique characteristics and adaptations that enable them to be effective hunters. They possess physical traits that distinguish them from other birds, along with specialized features for hunting and feeding.
Characteristics of Birds of Prey
Raptors exhibit several defining traits that enhance their predatory skills. Vision is one of their most notable characteristics; they have exceptional eyesight, allowing them to spot prey from great distances. The shape of their bodies also contributes to their hunting prowess. Many possess strong, streamlined bodies and sharp, pointed wings that facilitate swift flight.
Their beaks are hooked and strong, perfect for tearing flesh. Additionally, raptors feature powerful talons, which help grasp and kill prey effectively.
Common examples of birds of prey are eagles, hawks, and falcons. Each species exhibits unique color patterns and size variations, which can aid in camouflage and successful hunting strategies in their natural habitats.
Adaptations for Hunting
Adaptations in birds of prey are finely tuned for survival. Their extraordinary sense of sight is critical; they can detect ultraviolet light, giving them an edge in spotting potential meals.
Hunting strategies vary significantly among raptors. Some, like the Red-tailed Hawk, soar high to scan the ground while others, such as American Kestrels, hover in mid-air to locate prey.
Raptors also exhibit remarkable flight capabilities. Many can reach high speeds during dives, making them formidable hunters. Additionally, their foot structure allows for different gripping styles, enabling them to catch a variety of prey, from small mammals to fish.
This diversity in hunting techniques underscores their adaptability and efficiency in various environments.
Habitats in Colorado During Winter
Colorado’s diverse landscapes provide critical habitats for various birds of prey during the winter months. From mountainous regions cloaked in snow to open plains, these environments offer essential hunting grounds and nesting sites.
Mountain and Forest Regions
In the mountainous and forested areas of Colorado, elevation and terrain create unique habitats for birds of prey. Species such as the Northern Goshawk and Great Horned Owl thrive here, utilizing the dense tree cover for roosting and hunting.
The rugged terrain provides vantage points for soaring, allowing raptors to spot prey such as rodents and small mammals. Areas rich in coniferous trees are especially vital, offering shelter and nesting sites.
Winter storms may limit food availability, prompting these birds to expand their hunting range, sometimes venturing into lower elevations for sustenance. The combination of altitude and habitat complexity makes this region ideal for wintering raptors.
Plains and Open Fields
The expansive plains and open fields of Colorado present another important habitat for wintering birds of prey. Species like the Red-tailed Hawk and American Kestrel prefer these areas, where they can easily spot prey from a high perch or while in flight.
These open landscapes often host small mammals, which are crucial for the raptors’ diets. Tall grasses and sparse shrubbery provide excellent hunting grounds.
Farmers’ fields and pastures can also attract birds, particularly during feeding times when rodents are most active. The openness of the terrain allows for easy movement and hunting opportunities, making this region a significant habitat during the colder months.
