Vultures are unique and fascinating birds that play an important ecological role as nature’s clean-up crew. While they may not be the most beloved birds, vultures are incredibly interesting creatures worthy of appreciation. Let’s dive into 20+ fun facts about these underrated scavengers!
An Introduction to Vultures
Vultures belong to the family Cathartidae, which consists of 7 species found across North and South America, Africa, Europe, and Asia. Known as obligate scavengers, vultures primarily feed on carrion or decaying organic matter. They fill an essential niche in the ecosystem by disposing of diseased carcasses and preventing the spread of pathogens.
With their bald heads, sharp beaks, and hulking frames, vultures certainly look the part of Mother Nature’s janitors. But there’s more to them than meets the eye. Get ready to see vultures in a whole new light with these fascinating tidbits!
Vultures Have Heads Built for Scavenging
One of the most distinctive features of vultures is their bald heads which may look a bit odd but serve an important purpose. By lacking feathers, vultures can thrust their heads deep inside carcasses without matting down feathers which would otherwise prevent them from thermoregulating. Vultures’ heads and necks are also resistant to bacteria that would sicken other animals. Coupled with their highly acidic gastric juices, vultures have bodies literally built to clean up.
Turkey Vultures Use Their Sense of Smell to Find Food
Most birds rely on excellent vision rather than smell to forage. Turkey vultures buck this trend with a sense of smell that’s uncanny. Special cells called olfactory glands allow them to catch whiffs of ethyl mercaptan, a gas emitted as bodies decay. They can pick up scents from over a mile away to score their next meal!
Vultures Purge Their Stomachs When Threatened
Having a belly full of carrion makes taking off challenging. When vultures feel threatened, they are able to projectile vomit the contents of their stomachs to become light enough for a quick getaway. This habit also makes vultures in captivity rather messy!
Vultures Urine is Sanitizing
While vultures have strong stomach acid, their urine is sterile and harbors microbes that kill pathogenic bacteria from rotting meat. By urinating on their legs and feet, vultures self-sanitize after wading into disease-laden carcasses. Their urine is also a source of cooling through evaporation.
The Andean Condor Has the Largest Wingspan
The Andean condor, found in South America, lays claim to the largest wingspan of any land bird at over 10 feet! Their massive wings allow them to soar high without flapping for hours. These condors can scan 50 square miles in search of food from altitudes over 15,000 feet.
Adult Turkey Vultures Project Vomit at Their Young
Baby turkey vultures eagerly stick their heads in their parents’ mouths for a nourishing meal. However, adult vultures also regurgitate semi-digested meat when threatened, drenching their chicks in reeking vomit. This teaches the young vultures to also vomit as a defense mechanism once they fledge. Tough love!
New World Vultures Lack Syrinxes
Unlike other birds, New World vultures like the turkey vulture and black vulture cannot sing. They lack the syrinx organs that allow most avians to vocalize. While they can hiss, grunt, or moan, New World vultures do not have melodious calls. They do however have a good sense of hearing.
Vultures Get “Shredded”
The beaks of vultures are not designed for slicing or tearing flesh. As they dig into carcasses, bits of tissue, tendon, and skin cling to their beaks in long strings giving the vultures a tattered appearance. This grisly look earned them the nickname “shredded”.
Vultures Soar For Miles Without Flapping Their Wings
The expansive wingspans of vultures allow them to be expert gliders. By riding thermal columns of rising warm air, they exert minimal effort staying aloft while searching for carrion blowing in the wind. Their wing anatomy also reduces drag and turbulence, letting them gracefully cruise.
Vultures Keep Cool By Urinating and Defecating On Themselves
As bald scavengers in warmer climes, vultures need ways to regulate their body temperature. By urinating and defecating on their bare legs and feet, evaporative cooling helps them stay cool when foraging. Their bald heads also release heat efficiently.
Vultures Have Extremely Corrosive Stomach Acid
To safely ingest rotting carcasses teeming with dangerous bacteria like botulism and anthrax, vultures possess stomach acid that is extremely acidic, with a pH approaching 1! This potent gastric juice kills bacteria and even digests bone fragments that would obstruct other animals’ digestive tracts.
Egyptians Considered Vultures To Be Caretakers in the Afterlife
Ancient Egyptians revered vultures and considered them to be maternal caretakers in the afterlife. The vulture hieroglyph meant “mother”. The Egyptians observed vultures patiently watching over the dead, then swiftly swooping down to devour carcasses.
Griffon Vultures Mate For Life
Griffon vultures create strong social and mating bonds. A griffon will select a mate around age 5-7 and form lifelong pair bonds. Both parents share in incubating eggs and regurgitating food to feed their chicks. If one mate dies, the other will often stay single for years.
Vultures Have Adaptations to Eat Deadly Food
With digestive systems specialized for decomposing meat, vultures can safely ingest diseased carcasses lethal to other scavengers. Uric acid covers their legs as an antiseptic barrier. Long necks, beaks, and talons keep them at a distance from pathogens. They also have extremely tough immune systems.
Vultures Have Organs To Cool Their Blood
After gorging themselves on carrion, vultures could easily overheat from the energy required to digest. But they’re equipped with nasal passages containing blood vessels that function like radiators to cool circulating blood. This helps conserve energy for slow, low-flapping flight.
Carrion is Toxic to Most Other Animals
Putrescine and cadaverine are toxic chemicals emitted as animal tissue decays. While most creatures are sickened by these noxious compounds, vultures possess specialized enzymes and organisms allowing them to safely digest meat laced with toxins fatal to other scavengers.
Turkey Vultures Migrating Can Glide For 6 Hours Without Flapping
The aerodynamically-designed wings of turkey vultures allow them to be masters of long distance migration. Once they gain sufficient altitude from thermal convection, turkey vultures can remain aloft and travel for hundreds of miles by only extended gliding. This conserves energy for their marathon treks.
King Vultures Have Colorful Faces to Signal Dominance
The king vulture of Central and South America sports a vibrantly colored head and neck that stands out in contrast to its black plumage. These fleshy caruncles signal a king vulture’s health and dominance over carcasses when feeding in groups on the ground.
Vultures Have Excellent Eyesight
Myths paint vultures as nearly blind animals only finding food by smell. In fact, vultures have eagle-like vision to spot carcasses while soaring up to a mile high. Their eyes are specially adapted to see ultraviolet light reflected by the fluids of decaying bodies.
Vultures Can Soar as High as Jetliners
Riding rising thermals and updrafts, vultures can ascend as high as 37,000 feet — the lower limit of commercial airliners. From great heights with expansive views, they can scan the ground for dead animals. Ascending to cooler temperatures also prevents overheating.
Vultures Regulate Their Body Temperature By Pooping
To keep their massive bodies cool in hot weather, vultures defecate not only on their legs but also their stomachs and feet. As the feces evaporate, it draws heat away from their skin surfaces. This is similar to how elephants flap their ears for evaporative cooling.
Vultures Have Very Weak, Underdeveloped Feet
Because they spend most of their time in the air, vultures have small feet with talons designed for grasping rather than capturing or killing prey. Their feet lack strength compared to birds of prey. On the ground, vultures have difficulty walking without hopping clumsily.
Vultures Will Sometimes Feed Their Young By Regurgitating Into Their Mouths
Baby vultures hatch without fully formed legs and spend the early months of their life confined to the nest before they can walk or fly. Parents nurture the chicks by vomiting up partially digested carrion directly into their mouths.
Group of Vultures is Called a Venue, Volt, or Wake
Flocks of vultures have several intriguing names. When circling carrion aloft, a group is called a “kettle”. On the ground feeding, they form a “venue”. In flight or perched, vultures gather in a “volt” or “wake”. The term “committee” is used when vultures temporarily perch in trees.
Vultures Get “Safety In Numbers” At Roosts
While solitary outside of breeding, vultures congregate in large numbers at communal roosts, sometimes numbering thousands of birds. There is safety from predators like coyotes or bobcats when gathering in droves. The body heat from densely-packed vultures also keeps them warm.
Black Vultures Will Attack and Dominate Turkey Vultures
While turkey vultures rely on an acute sense of smell to find carcasses, black vultures are more aggressive and possessive of discovered food sources. Black vultures will chase, out-compete, and even kill turkey vultures to appropriate a tasty carcass for themselves.
Vultures Provide Sanitary Services And Prevent Disease
Beyond keeping ecosystems tidy, vultures combat the spread of dangerous diseases like anthrax and botulism. By rapidly scavenging carcasses soon after death, vultures curtail microbes that would otherwise contaminate soil and water from festering carcasses.
Vultures Have Corrosive Vomit
As a second gut defense beyond stomach acid, Turkey vultures can spew acidic vomit containing uric acid and pathogens drawn from decomposing bodies. This noxious spray both repels predators and kills microbes from rotting meat that could sicken the birds.
New World Vultures Practice Urohidrosis
In hot tropical environments New World vultures urinate on themselves for evaporative cooling and cleansing. Uric acid crystals in the urine also kill microbes picked up from carcasses. This urohidrotic habit keeps the birds cool and sanitary.
Vultures Can Eat Up To 30% of Their Body Weight
With stomachs stretching to accommodate huge meals, vultures can consume impressive quantities of carrion. During active feeding, a vulture may gorge until it has eaten up to 20-30% of its own body weight. This minimizes energy spent hunting by maximizing calories from feast-or-famine feeding.
Vultures Have Unique Feathering on Their Heads
Most vultures sport only bristly filoplumes on their bald heads. But the king vulture and bearded vulture grow decorative plumage adding to their distinct appearance. These specialized feathers likely play a role in thermoregulation and communication.
In Conclusion
After learning about vultures, it’s clear there’s more to these birds than meets the eye. From advanced adaptations allowing them to safely consume rotting carcasses to their impressive soaring abilities, vultures truly are remarkable creatures. While considered repulsive by some, they provide valuable ecological services and deserve respect for their evolutionary ingenuity. The next time you spot a vulture overhead or cleaning up roadkill, take a moment to appreciate Mother Nature’s unsung sanitation workers!

Frequently Asked Questions About Vultures
What do vultures eat?
Vultures are scavengers, meaning they primarily eat carrion or the decaying flesh of dead animals. They do not kill live prey themselves. With their sharp beaks and strong talons, vultures tear into carcasses of large mammals like deer, cattle, and elk. They also feed readily on roadkill.
Why are vultures bald?
Most vulture species have bald heads which allows them to reach deep inside rotting carcasses without matting their feathers with blood and gore. Their bare heads and necks are also adaptive for thermoregulation in hot environments.
How do vultures find food?
Turkey vultures rely on their keen sense of smell to detect gasses produced by decay from up to a mile away. Black vultures visually spot carcasses while soaring at high altitudes. Groups of circling vultures congregating overhead indicate a food source.
Do vultures carry disease?
Remarkably, vultures do not typically get sick from the diseased carcasses they eat. Their stomach acids are intensely corrosive, killing most bacteria and viruses. Vultures also have tough immune systems. By scavenging, they help prevent the spread of disease.
Why do vultures spin while flying?
Vultures will soar in wide circles on thermals rising from the ground below. This circling behavior allows them to gain altitude effortlessly without flapping their wings and scan below for carrion. Their gliding flight pattern looks like spinning from a distance.
Are vultures intelligent?
Studies indicate that vultures display relatively high intelligence compared to other birds. They demonstrate cooperative social behaviors, problem solving skills, and acute sensory capabilities that provide competitive advantages when scavenging. Vultures also use tools to access carcasses.
Are vultures dangerous?
Vultures will avoid contact with live animals and pose no direct threat to pets or livestock. While formidable at a carcass, vultures prefer flight over fight. However, exceptionally rare cases of turkey vultures attacking live calves and lambs have been documented.
Why do vultures spread their wings when it’s hot?
Unlike other birds, vultures will extend and spread their wings to cool down on excessively hot days. By positioning their wings perpendicular to the sun’s rays, bare skin patches help release heat buildup through convection.
Do vultures mate for life?
Some vulture species demonstrate lifelong pair bonding between mates such as griffon vultures. However, other vultures have more fluid social lives and mating relationships. But both parents invest significant time and energy raising their chicks.
How long do vultures live?
In the wild, vultures can live 20-25 years on average. With steady food sources and no threats, they may reach 30 years or more. In captivity the lifespan is considerably longer at 50-60 years, evidenced by zoo populations.
