9 Most Common Hawks in Colorado

1. Red-Tailed Hawk

One of the most iconic hawks in Colorado is the red-tailed hawk. With its distinct red-colored tail, this species is easily recognizable. The red-tailed hawk, scientifically known as Buteo jamaicensis, is a large hawk commonly found in open habitats throughout North America. In Colorado, they can be spotted soaring high in the sky or perched on tree branches, utility poles, or fence posts.

Buteo jamaicensis is a highly adaptable species, capable of thriving in a wide range of environments, from grasslands and deserts to forests and urban areas. However, they are most commonly associated with open areas that provide suitable hunting grounds, such as fields, meadows, and agricultural lands.

Habitat

The red-tailed hawk is a resident species in Colorado, meaning they can be found in the state throughout the year. They are especially abundant in the eastern plains and foothills regions, where their preferred habitat of open grasslands and agricultural fields is abundant.

Although they are adaptable, red-tailed hawks require a mix of open areas for hunting and nesting, as well as perching spots such as tall trees or utility poles for scouting prey and resting. They are known to build their nests high above the ground, often reusing the same nest year after year.

Behavior

As skilled hunters, red-tailed hawks have a varied diet consisting of small mammals, birds, reptiles, and even carrion. They are known for their impressive aerial displays, soaring high above the ground with their broad wings and scanning the terrain for potential prey. Once they spot their target, they swoop down with great speed and accuracy to capture it with their sharp talons.

Red-tailed hawks are known for their distinctive call, often described as a high-pitched screech. This call is frequently heard during their courtship displays and territorial encounters with other hawks.

Physical Characteristics

Red-tailed hawks are large birds of prey, measuring around 18 to 26 inches (45 to 65 cm) in length and weighing between 1.5 to 3.5 pounds (0.7 to 1.6 kg). They have a wingspan of approximately 3 to 4 feet (0.9 to 1.2 meters). Their plumage varies depending on their age and geographical location.

These hawks are best known for their red-colored tail feathers, which are most visible during flight. However, it’s important to note that juvenile red-tailed hawks have a brownish tail that gradually changes color as they mature. They also have a characteristic dark belly band and a pale underside with a speckled appearance.

Below is a table summarizing the main characteristics of the red-tailed hawk:

Characteristic	Description
Size	18 to 26 inches (45 to 65 cm) in length
