No, buzzards and vultures are not the same bird. While they may look similar and fill similar ecological niches, buzzards and vultures belong to different taxonomic families. Buzzards are members of the Accipitridae family while vultures belong to the Cathartidae family. However, there is some confusion between the terms because in North America, the bird known as a “turkey vulture” is actually a type of buzzard. But turkey vultures aside, true buzzards and true vultures have distinct differences when it comes to their physical characteristics, geographic ranges, diets, and behaviors.
Key Differences Between Buzzards and Vultures
Here is a quick overview of the main ways buzzards and vultures differ:
– Taxonomy: Buzzards are Accipitridae, vultures are Cathartidae. They are related but distinct bird families.
– Range: Buzzards live on all continents except Antarctica and Australia. Vultures live in the Americas, Africa, and Eurasia.
– Size: Buzzards are generally smaller than vultures.
– coloring: Buzzards have more colorful and variable plumage while vultures are more uniformly black, grey, or brown.
– Beaks: Buzzards have sharper, more hooked beaks than vultures.
– Feet: Buzzards have talons to grasp prey while vultures have flat feet.
– Flight: Buzzards soar and flap when flying, vultures soar for hours without flapping.
– Diet: Buzzards are carnivorous and eat small animals they hunt. Vultures are scavengers and eat decaying carcasses.
– Vomit: Vultures can vomit at will as a defense mechanism, buzzards cannot.
– Baldness: Many vulture species have bald heads, buzzards are fully feathered.
Let’s explore some of these differences in more detail.
Taxonomy and Classification
Buzzards and vultures may occupy similar ecological niches around the world, but they are taxonomically distinct.
Buzzards are medium-sized raptors that belong to the Accipitridae family. The Accipitridae includes hawks, eagles, kites, and harriers. There are roughly 60 species of buzzard worldwide. Some common examples include the common buzzard, the red-tailed buzzard, and the long-legged buzzard.
Vultures belong to the Cathartidae family. There are just 7 species of vulture, including the turkey vulture, the black vulture, and the Andean condor. The Cathartidae are sometimes called the New World Vultures, since vultures are found exclusively in the Americas.
So while buzzards and vultures may appear and behave similarly in some ways, they are not closely related. Their last common ancestor lived over 10 million years ago. They evolved independently to fill scavenging and hunting niches in their respective environments and separated into distinct families as they diversified.
Geographic Range
Another key difference between buzzards and vultures is their geographic distribution around the world:
Buzzards are found on every continent except Antarctica and Australia. They occupy diverse habitats including forests, grasslands, deserts, and wetlands. Some species migrate long distances seasonally while others occupy the same region year-round.
Vultures are found exclusively in the Americas, Africa, and Eurasia. There are no native vultures in Australia or Antarctica. Like buzzards, vultures live in diverse regions ranging from tundra to deserts to rainforests. The turkey vulture and black vulture are the two vulture species found in the Americas. The griffon vulture, cinereous vulture, and Egyptian vulture are Eurasian species. The Cape vulture, lappet-faced vulture, and other species occupy Africa.
So while their ranges overlap in certain parts of the Americas, Africa, and Eurasia, globally buzzards have a much wider distribution than the more limited vultures.
Size Differences
There is also generally a size difference between buzzards and vultures.
Most buzzards have a total length around 18-25 inches (45-65 cm) from bill to tail. Their wingspans range from roughly 4 to 5 feet (120-150 cm). Most buzzards weigh between 1-5 pounds (0.5-2.5 kg).
Vultures tend to be significantly larger than buzzards. They have total lengths between 25-40 inches (65-100 cm), wingspans of 6 to 11 feet (180-350 cm) and weigh between 5-30 pounds (2-14 kg). The massive Andean condor has a 10 foot wingspan and can weigh up to 33 pounds!
The larger size of vultures correlates with having to consume larger carcasses. Their broad wings allow them to soar for very long periods without flapping as they scan the landscape for dead animals below. The smaller buzzards are more agile hunters capable of swiftly pursuing and capturing live prey.
Plumage Differences
Buzzards and vultures also differ noticeably when it comes to their plumage:
Buzzards exhibit much more variety in their plumage than vultures. Most buzzard species have brown, black, or gray backs and wings and lighter undersides. But many also have white markings on their wings, ruffs around their necks, or brightly colored tails, faces, or crowns. This can include striking red feathers on tails and faces. And juvenile buzzards often appear quite different than the adults.
Vultures generally have more drab and uniform plumage, though there are some exceptions. Most New World vultures are black or gray overall. The king vulture has striking coloration with a multi-colored head and neck. Old World vultures are generally brown, black, or gray. But most lack the accents and variety found in buzzard plumage.
The more colorful buzzard plumage likely plays a role in mating displays. Vulture coloration is likely cryptic, providing camouflage as they scan for carcasses.
Turkey Vultures
One exception is the turkey vulture found in the Americas. Despite the name, this is actually a type of buzzard belonging to the Cathartes genus. Turkey vultures have a featherless red head and silvery-brown plumage similar to other buzzards. This demonstrates how common names like “vulture” don’t necessarily reflect the correct taxonomy.
Beak Differences
The beaks of buzzards and vultures, specialized for their respective diets, also show marked differences:
Buzzards have sharp, hooked raptor beaks with a sharp tip and cutting edges. They use these beaks to swiftly kill small prey like rodents, reptiles, amphibians, and sometimes rabbits. The hooked tip helps buzzards tear meat and flesh into smaller chunks.
Vultures have much thicker, bulkier beaks. The keratin sheath at the tip of a vulture’s beak can be as long as 2.5 inches! This allows vultures to quickly rip open the tough hides and connective tissue of carcasses. But their beaks lack the sharpness and grasping ability of a buzzard’s raptor beak.
These adaptations allow each type of bird to utilize their food source. The buzzard beak helps subdue and shred live prey while the vulture beak allows them to reach deep inside rotting carcasses.
Foot Differences
Buzzards and vultures also differ in their feet:
Buzzards have feet with sharp, curved talons used to grab and carry prey. Their feet help them lock onto and subdue struggling animals. The talons are not as large or powerful as those of larger raptors like eagles, but are deadly to small animals.
Vultures‘ feet are not equipped with grasping talons. Instead, they have relatively flat feet with short, blunt nails. Since they do not kill live prey, vultures simply use their feet for perching and walking. The flat nature helps distribute their weight when standing on carcasses.
So buzzards and vultures once again show perfect adaptations for their ways of obtaining food. Talons help buzzards seize prey while flat feet allow vultures to sprawl over decaying bodies.
Flight Patterns
There are also distinct differences between how buzzards and vultures utilize flight:
Buzzards employ a mix of soaring and active flapping flight. They Flap frequently to gain altitude, pursue prey, or maneuver through forests. Buzzards are agile fliers, allowing them to deftly move through cluttered environments.
Vultures are masters of soaring on thermals and rarely need to flap their enormous wings. They can soar for hours without a single wing beat! Soaring flight allows vultures to scan massive areas for potential food sources. But it comes at the cost of maneuverability in tight spaces.
Turkey vultures exhibit vulture-like flight patterns. Their shorter, broader wings and light body weight allow them to effortlessly ride warm air currents. This supports the fact that they are in the vulture family despite the name “buzzard”.
Diet and Hunting
Perhaps the biggest differences between buzzards and vultures relate to their diets and feeding strategies:
Buzzards are carnivorous hunters that use their keen eyesight and agile flight to seek out and kill small live prey. They eat mammals like rats or rabbits, reptiles and amphibians like snakes and frogs, insects, and other assorted small animals. Buzzards locate prey while soaring overhead, then swoop down to strike and kill with their talons and beak.
Vultures are exclusively scavengers, feeding only on carrion. They soar for long periods searching the landscape for the smell of dead animals. Once found, vultures descend to feed on the carcass communally. Their strong beaks and acid-resistant guts allow them to consume rotting flesh, hide, and bone.
Some key differences arise from the buzzard’s carnivorous diet and the vulture’s scavenging needs:
– Cooperative feeding – Vultures often feed socially in large groups at carcasses. Buzzards are solitary hunters and do not feed together.
– Carrion detection – Vultures locate food using excellent eyesight and sense of smell. Buzzards rely on eyesight alone.
– Disease resistance – Vultures have highly resistant digestive systems to handle rotting meat and bacteria. Buzzards deal with fresher kills.
– Conservation Role – By disposing of carrion, vultures help limit the spread of diseases. Buzzards help control rodent and pest populations.
So buzzards hunt and eat fresh flesh while vultures wait patiently to clean up carcasses. These techniques align perfectly with each species’ physical attributes.
Vomit as a Defense
One very conspicuous difference between buzzards and vultures relates to their vomit:
When threatened, vultures can voluntarily regurgitate the contents of their stomach as a defense mechanism. This foul smelling and acidic vomit deters potential predators.
Buzzards cannot vomit at will and must rely on other defenses like biting, clawing or mobbing predators.
Vultures can produce vomit on demand thanks to their unique digestive systems. The digestive acid is stored in an extra chamber between the crop and stomach. This allows quick access when needed. Buzzards lack this special chamber and cannot spew vomit as readily.
Baldness of Vultures
Most vulture species have bare heads lacking feathers. This unique adaptation serves multiple purposes:
– Feeding – Bald heads avoid contamination by bacteria from carcasses.
– Thermoregulation – Bare skin releases more heat during flight and while feeding.
– Health – Feathers could trap dangerous bacteria against the face and neck.
– Hygiene – Lack of feathers allows self-cleaning of sanitized skin.
Buzzards retain a normal feathered head and do not share these adaptations. Since they eat relatively fresh kills, exposed skin offers less advantage. Their feathered heads likely play more of a role in mating displays.
Summary of Differences
In summary, while buzzards and vultures appear similar and occupy scavenging or hunting niches, key differences exist:
Trait | Buzzards | Vultures |
---|---|---|
Taxonomy | Accipitridae Family | Cathartidae Family |
Range | Worldwide except Australia & Antarctica | Americas, Africa, Eurasia |
Size | Smaller | Larger |
Plumage | More colorful and variable | Drab blacks and browns |
Beaks | Sharp, hooked | Blunt, thick |
Feet | Talons | Flat feet |
Flight | Flapping and soaring | Soaring only |
Diet | Hunts fresh prey | Scavenges carrion |
Vomit | Cannot regurgitate | Can vomit at will |
Head | Feathered | Bald in most species |
So in summary, buzzards and vultures belong to different families and exhibit clear differences in anatomy, geography, behavior, and ecology despite some superficial similarities. Turkey vultures demonstrate that naming does not always reflect taxonomy accurately. But searching deeper into classification, adaptation, and habitat reveal buzzards and vultures to be distinct bird types that have each evolved to thrive in their own way.
Buzzards vs. Vultures – Regional Examples
To further demonstrate the differences between these two types of birds, let’s take a closer look at some specific examples of buzzards and vultures from different regions of the world:
Europe and Asia
In Europe and Asia, typical buzzards include:
– Common Buzzard – Medium-sized raptor with variable brown plumage. Hunts small mammals, birds, and reptiles.

– California Condor – Huge endangered vulture with nearly 10 foot wingspan.
Conclusion
To conclude, buzzards and vultures have distinct taxonomy, anatomy, ecology, and behavior demonstrating they are different types of birds. Buzzards are carnivorous raptors that belong to the Accipitridae family. Vultures are obligate scavengers from the Cathartidae family. While they may appear similar at first glance, closer examination reveals key differences in their plumage, feet, flight patterns, diet, and ability to regurgitate. Regional examples from around the world highlight diverse species of both buzzards and vultures. So next time you see a large soaring bird, look closely to determine if it is a vulture or a buzzard! Despite some confusion caused by naming, these fascinating birds show amazing adaptations to their way of life.
