We know Thanksgiving usually centered around turkeys. But variety is the spice of life, right? So for your pre-Thanksgiving entertainment, here are a few fun facts about turkey vultures:

A group of turkey vultures is called a committee, or a kettle if in flight, or a wake if they're feeding.
The scientific name means "cleansing breeze."
Turkey vultures can travel up to 200 miles in a day.
Their feet are useless for killing prey, but beaks are strong enough to rip through cow hide.
A bald head prevents a delicious meal of dead meat from getting stuck to their feathers.
What an incredible sense of smell! The wafting aromas of dead animals can be picked up from over a mile away.
They sometimes eat so much that they can't take off or fly until they digest some of their meal.
Turkey vultures vomit when they feel threatened.

Ok, who's ready for a holiday dinner?!

Before you get too involved in decorating, cooking, and enjoying, please mark your calendars for Giving Tuesday on December 1. Think Black Friday or Cyber Monday, but better! You can donate to support Madison Audubon's work through our website, any amount, at madisonaudubon.org/gt

A dark, brooding, and indifferent bird, reading the wind like a well-worn novel, the muse of mortality. Taking a thermal, teetering against the wind, soaring in circles, the turkey vulture's mysticism is imagined from a dark and deceased place.

Turkey vultures projectile vomit to defend themselves from predators or intruders.

Edward Abbey imagined himself in “the fierce greedy eyes and unimaginable consciousness of a turkey vulture... soar[ing] on motionless wings high over the ruck and rack of human suffering. For most of us a promotion in grade, for some the realization of an ideal.” An accessible bird, vultures can easily be spotted soaring in the midday sun. Indolent up there, skimming thermals above it all, turkey vultures aren't difficult to track, and their dihedral V-shaped wings are diagnostic.

People often see vultures along the roadside, cleaning up carrion. Groups of turkey vultures last seen among the cumulus will congregate around deceased animals. The habit of scavenging may seem repulsive to some, but turkey vultures play an important ecological role. They clean the earth of its dead flesh. Able to metabolize biotoxins in decaying animals, turkey vultures filter the right-of-ways of roads across America, roads so ubiquitous that it is more accurate to talk about where roads aren't (“roadless areas”) than where they are. The vehicular swarm covering the continent bodes well for vultures, since animals end up crossing these roads for resources or migration. An animal that has crossed enough roads will eventually meet its Buick; until then the turkey vulture waits.

On a warm summer day I trudge into an old field in the process of being converted to tallgrass prairie. Over the stubble of a soy field comes a turkey vulture, flapping its wings as it rocks to the east. I've never seen a vulture work so hard. It flaps its wings hard, rising above the soy and fencerows. Ambition, perhaps, or the bird found something interesting, maybe even edible.

A sharp sense of smell allows the turkey vulture to identify sources of prey. One of a few birds with olfactory expertise, turkey vultures can be alerted to dead flesh by as little as a few parts per trillion in the air. For this reason, black vultures, which lack a developed sense of smell, will follow turkey vultures to a carcass and harass the turkey vultures away from the prize.

In Texas, researchers at the Texas State Forensic Anthropology Research Facility are using vultures for a unique reason: to solve crimes. In a delusive field in Texas, researchers have scattered remains throughout the bluestem and mesquite of the Texas blackland prairies. Theses remains that they've scattered are human. Hoping to nail down the chronology of a crime, turkey vultures could help solidify a timeline, and this research is helping to better identify subjects as they decompose. Dirty work, but work the turkey vulture is cut out for.

The avoidance of death and dead bodies in western cultures wasn't always that way. Up to and even beyond the nineteenth century, churches and crypts in Europe were sometimes decorated with human bones, known as ossuaries, sublime art that provided a link to the dead. Linked with dead bodies, turkey vultures loiter in the land of Poe and Hollywood horror.

Yest, many cultures still revere vultures as a necessary and welcomed birds. Its scientific name (Cathartes aura) means “purifying breeze.” Throughout India and Tibet, a practice known as a sky burial commences upon death, and the turkey vultures remove the body from the earth. Interestingly, Disney's The Jungle Book movie touches on the importance of vultures in Indian culture. The four vultures sitting in the tree quipping “whatchya wanna do? I dunno what you wanna do?” end up saving Mowgli. Rewatched with my well developed “loathing” of vultures, the song “What'cha Wanna Do” becomes almost comical. The birds sing, “When you're alone/ who comes around/ to pluck you up/ when you are down.” These are the precise habits of a turkey vulture, but they are seen as friends in this bildungsroman.

Different species of vultures are found throughout the world. The Turkey Vulture and Black Vulture are known as New World vultures. Yet none of the old world vultures are even found in the same family as turkey vultures. This suggests a convergent evolution for the role of scavengers in the sky, high soaring birds with bald heads. These bald heads are another reason to admonish the turkey vulture, yet these too serve a purpose. Its pink head keeps it clean as it scavenges and helps prevent disease. A bird with a fully feathered head poking around in carcasses wouldn't be the cleanest and must have been selected against.

On the east coast, turkey and black vultures have become a bit of a problem. Suburbanization tends to favor these birds, as more roads mean more roadkill (to a point) and more landfills. The vultures have been nesting in suburban neighborhoods where their excrement runs down trees and splatters rooftops. A black mass of hundreds of vultures probably violates the suburban aesthetic. As a result he USDA's Animal and Plant Health Inspection Service (APHIS) has harassed tens of thousands of vultures in suburban areas. It is speculated that the black vultures are moving north, partly due to climate change. A warming climate means that the line where carcasses used to freeze is headed north. Along this line, the vultures tip their wings as they pass the growing human populations along the coast. Tipping their wing, thankful for the landfills and the roadkill .

In Wisconsin, turkey vultures often nest on cliffs or concrete structures, secluded from human populations. But about 9 am daily, the vultures soar high above the glacial plains, perhaps seeking an urban heat island, looking for a thermal. Driving on I-94 to the east, past Johnson Creek, I see about 50 vultures hovering over a landfill. Gorging themselves on the offal of our society, turkey vultures are doing alright.
