Birds that have claws on their feet belong to a group known as raptors. Raptors are birds of prey that use their sharp talons or claws to catch and kill other animals for food. Some examples of raptors with claws include eagles, hawks, falcons, owls, and vultures.
Birds of Prey that Have Claws
Here are some of the main types of raptors that have claws on their feet:
Eagles
Eagles are large birds of prey that are known for their sharp talons and keen eyesight. There are over 60 different species of eagles in the world. Some examples include:
– Bald Eagle – National bird of the United States with yellow claws and feet.
– Golden Eagle – Widespread in the Northern Hemisphere with yellow claws.
– Harpy Eagle – Powerful bird of prey from Central and South America. Has huge claws up to 5 inches long.
– Steller’s Sea Eagle – Largest eagle in the world found in coastal regions of Russia and Asia. Has yellow claws.
Hawks
Hawks are medium-sized raptors found worldwide. There are over 300 species of hawks. Some hawks with claws are:
– Red-Tailed Hawk – One of the most common hawks in North America. Has dark brown bands on its tail.
– Harris’s Hawk – Found in desert areas and scrublands of the Americas. Hunts in groups.
– Northern Goshawk – A forest-dwelling species found across Eurasia and North America. Has bright red eyes.
– Swainson’s Hawk – Breeds in western North America and migrates to South America for the winter. Has dark brown plumage.
Falcons
Falcons are swift predatory birds that specialize in diving at prey from great heights. They have tapered, pointed wings and medium-sized claws. Some species include:
– Peregrine Falcon – The fastest animal on Earth when diving. Found on every continent except Antarctica.
– Gyrfalcon – A large falcon from arctic and subarctic regions. Prized by falconers.
– American Kestrel – The smallest and most common falcon in North America. Has colorful plumage.
– Merlin – A small falcon found throughout temperate regions around the world. Feeds on smaller birds.
Owls
Owls are nocturnal and crepuscular raptors. They have forward-facing eyes, excellent hearing, and sharp talons used to grab prey. Some clawed owls include:
– Great Horned Owl – One of the most widespread owls in the Americas. Has prominent ear tufts.
– Snowy Owl – A white owl of the Arctic known for its cryptic plumage. Hunts during the day.
– Eurasian Eagle-Owl – One of the largest owl species with a wingspan up to 6 feet. Found across Eurasia.
– Eastern Screech Owl – A small owl native to North and Central America. Comes in gray and red color morphs.
Vultures
Vultures are scavengers that use their claws to hold and rip apart carrion. Unlike other raptors, they do not actively hunt live prey. Some vultures with claws include:
– Turkey Vulture – A widespread vulture in the Americas known for its red, unfeathered head.
– King Vulture – The most colorful vulture found in Central and South America. Has vividly colored plumage.
– Bearded Vulture – An Old World vulture species that feeds mainly on bones. Has unique bristles on its beak.
– California Condor – The largest North American land bird. Was nearly extinct but conservation efforts have increased populations.
Raptor Claw Form and Function
Raptors have specialized claws adapted for catching and killing prey. Here are some key features of raptor talons:
Sharpness
The claws of raptors are sharp and curved to tightly grip prey. Eagles, hawks, and owls have some of the sharpest claws which they use to puncture vital organs and kill prey quickly.
Strength
A raptor’s talons generate a tremendous amount of squeezing power. For example, the claws of a harpy eagle can exert 500 psi or more – enough force to easily crush bones.
Length
Lengthy claws give raptors extra reach to snatch prey. Long claws also allow owls to get a stable grip on prey larger than the owl’s own body size.
Movement
Raptors can spread and close their toes widely to adjust grip on prey while flying. They have opposable hind claws that can swivel forwards and backwards for maximum maneuverability.
Numbers
Most raptors have three claws facing forward and one pointing backwards on each foot. The arrangement helps them grasp and carry prey efficiently.
Non-Raptors with Claws
While most clawed birds are raptors, some non-raptors also have claws on their feet:
Roads and Crows
Roads like ravens, crows, and jays belong to the Corvidae family. They have four toes on each foot with long, curved claws used for grasping.
Parrots
Parrots have two forward facing toes and two back facing toes with claws on each foot. The claws help parrots climb and grip branches.
Woodpeckers
Woodpeckers have four toes, two pointing forward and two back, with sharp curved claws. Their claws help them cling tightly to tree trunks.
Kingfishers
Kingfishers have three front facing claws and one rear facing claw per foot which they use to grasp fish and perch on branches.
Turacos
Turacos are African near-passerine birds that have elongated middle and rear facing toes with claws adapted for tree climbing.

Claw Adaptations for Habitat and Prey
Different raptor claws are adapted for catching prey in specific habitats:
| Bird of Prey | Claw Adaptations | Habitat | Prey |
|---|---|---|---|
| Bald Eagle | Large, dagger-like talons | Coastal areas and rivers | Fish, water birds, small mammals |
| Peregrine Falcon | Short, powerful claws | Cliffs, cities, wetlands | Other birds like pigeons and ducks |
| Snowy Owl | Thick claws insulated with feathers | Arctic tundra | Small mammals like lemmings and voles |
| Red-tailed Hawk | Robust, versatile claws | Various open and wooded habitats | Small mammals, snakes, lizards |
| Great Horned Owl | Long, muscular claws | Various forests and open habitats | Reptiles, amphibians, small mammals, birds |
Claw Care and Wear
Raptor claws are subject to wear and tear from catching and handling prey. Here are some ways raptors maintain their talons:
Sharpening
Raptors sharpen their claws by scratching trees and scraping against abrasive surfaces. This helps hone their talons’ cutting edges.
Bathing
Bathing cleans dirt and debris from raptors’ feet and claws. It helps prevent bacteria or infection.
Preening
Preening with their beaks removes detritus and straightens feathers around the feet and claws. This helps claws stay in top condition.
Molting
Molting, or shedding old worn claws, allows new sharp talons to take their place. Most raptors molt their claws once a year.
Exercising
Raptors exercise their feet regularly by flexing their toes and opening and closing their claws. This maintains strength and mobility.
Clawed Feet Compared to Talons
Though often used interchangeably, claws and talons refer to slightly different structures on birds’ feet:
Claws
Claws are curved, pointed keratin structures on the end of a bird’s toes used for grasping, climbing, digging, fighting, or prey capture. All birds have claws.
Talons
The term talon specifically refers to the large, powerful claws of birds of prey. They use their talons to grip and kill prey.
Key Differences
| Claws | Talons |
| – Found on all birds | – Specific to raptors |
| – Tend to be shorter and less curved | – Longer and more sharply curved |
| – Used for a variety of functions | – Specialized for hunting and killing |
| – Can be found on bird toes or wings | – Only found on raptor feet |
So while all raptors have talons, not all birds with claws have talons. But in casual usage, the terms are often used interchangeably.
Conclusion
In summary, raptors like eagles, hawks, falcons, owls, and vultures have sharp, curved claws or talons on their feet. Their talons help them catch and kill prey effectively. Other birds like crows, parrots, and woodpeckers also have clawed feet suited to their lifestyles. A raptor’s claws are adapted for its habitat and diet, and need proper care and maintenance. Though sometimes used synonymously, talons specifically refer to the large claws of predatory birds. So next time you see a bird with claws, it just might be a raptor!
