What kind of hawk has feathered legs? The Rough-legged Hawk is known for its distinctive feathered legs, a feature that helps it survive in cold climates. These hawks are commonly found in the Arctic and migrate to the northern United States during winter. Their feathered legs provide insulation against harsh weather, making them well-suited for life in cold environments.
What Are Rough-Legged Hawks?
Rough-legged Hawks, scientifically known as Buteo lagopus, are medium-sized birds of prey distinguished by their unique adaptation of feathered legs. This feature sets them apart from most other hawks, which typically have bare legs. The feathers cover their legs down to the toes, providing extra warmth during the cold months.
Habitat and Distribution
These hawks breed in the Arctic tundra and migrate southward to North America during winter. They are often seen in open fields, marshes, and prairies, where they hunt for small mammals. Their migration pattern is influenced by the availability of prey, primarily voles and lemmings.
Physical Characteristics
- Size: Rough-legged Hawks measure about 18-24 inches in length with a wingspan of 52-54 inches.
- Appearance: They have a light-morph and a dark-morph variant. The light morph has a pale underbelly with dark patches, while the dark morph is almost entirely brown.
- Feathered Legs: The most distinctive feature is their fully feathered legs, which help them adapt to cold climates.
Why Do Rough-Legged Hawks Have Feathered Legs?
The feathered legs of Rough-legged Hawks serve as an adaptation to their cold environment. This feature provides several benefits:
- Insulation: The feathers trap heat, keeping the hawks warm in frigid temperatures.
- Camouflage: The feather patterns help them blend into their snowy surroundings, aiding in hunting and avoiding predators.
- Protection: Feathers protect their legs from injury while hunting in rough terrains.
How Do Rough-Legged Hawks Hunt?
