Appearance
The Red-tailed Hawk is a robust raptor with broad, rounded wings and a short, wide tail. Its upperparts are dark brown, while the underparts are pale with a streaked belly band. The namesake red tail is visible in adults, appearing brick-red above.
Females are typically 25% larger than males but share similar plumage. Juveniles lack the red tail, instead showing a brown tail with narrow dark bands. Regional color variations exist, ranging from light to dark morphs.

Attributes
Understanding Attributes
Rated 0–100 based on research and observation. A score of 50 is average across all bird species. These attributes are relative and don't necessarily indicate superiority.
Habitat & Distribution
Red-tailed Hawks inhabit a wide range of open and semi-open habitats, including woodlands, prairies, deserts, and urban areas. They are found across North and Central America, from Alaska to Panama.
In the United States and Canada, they are year-round residents in many areas. Northern populations tend to migrate south for winter, while those in temperate regions often remain in their territories throughout the year.
Distribution
Diet
Red-tailed Hawks are versatile predators, primarily feeding on small to medium-sized mammals such as rabbits, squirrels, and rodents. They also consume birds, reptiles, and occasionally insects.
These hawks employ a 'sit-and-wait' hunting strategy, swooping down on prey from elevated perches.
Behaviour
Red-tailed Hawks are often seen perched on tall structures or soaring in wide circles high above open fields. They use their keen eyesight to spot prey from these vantage points.
During courtship, pairs perform impressive aerial displays, sometimes locking talons mid-flight and spiraling towards the ground.
Calls & Sounds
The Red-tailed Hawk's call is a distinctive, hoarse scream described as 'kee-eeeee-arr,' often lasting 2-3 seconds. This vocalization is so iconic that it's frequently used in movies to represent eagles or other raptors.
During courtship, pairs may call together with a series of raspy cries.
Nesting & Breeding
Red-tailed Hawks typically form monogamous pairs that may mate for life. Breeding season varies by region but generally occurs from March to May in North America.
Nests are large structures of sticks lined with bark strips, fresh foliage, and dry vegetation. They are usually placed high in a tree or on a cliff ledge. Females lay 2-3 eggs, which are white or pale blue with brown spots.
Incubation lasts about 28-35 days, primarily done by the female. Nestlings fledge after 42-46 days but remain dependent on their parents for several weeks after leaving the nest.
Conservation
Red-tailed Hawks are currently listed as Least Concern due to their large range and stable population. However, they face threats from habitat loss, collisions with vehicles and structures, and secondary poisoning from rodenticides.
Conservation efforts focus on protecting nesting sites and reducing the use of harmful pesticides.
Population
Estimated: 3,100,000 mature individuals[3]
Trend: Increasing[2]
Population increasing due to adaptability to human-altered habitats
Elevation
Sea level to 3,200 meters
