When and where I grew up turkey vultures were always called
“buzzards.” I was probably 40 before I learned their proper common name.
I was a small-town/farmer-lite girl so I’ve known how to
identify a vulture in flight since I was probably 10, but I’ve only relatively
recently considered that their wing position offers vultures something other
than just a place to put their wings. Those wings held in the recognizable V
allow these huge birds with their six-foot wingspans to coast along on the
thermals, letting them conserve energy as they look for and then circle over
their food on the ground.
Although they appear black against the sky, when you see a
turkey vulture at ground level, up-close and personal, as I often do these days,
you notice some lighter streaks on their wings sometimes. At least a few of the vultures in my current
neck of the woods have very light wing tips, looking like they’ve donned white
dinner gloves in dressy anticipation of their upcoming feast of tasty squirrel,
possum or other dead, stinking morsel. Along with that set of impressive black wings, one of the most
recognizable features of the turkey vulture, is of course, that fleshy red
head, resembling, of course, a turkey’s.
According to the Indiana Department of Natural Resources
“committee” is the collective noun for a group of perching vultures. Gathering
in committee, creating a brand, thinking about lunch. The DNR also reports that
turkey vultures are protected by state and federal law under the USA by the Migratory
Bird Treaty Act. So, don’t go vulture
hunting. Cause I WILL turn you in.
Indiana’s ornithological types have been taking note of
turkey vultures since at least 1892. That year Amos William Butler wrote in The Birds of Indiana: With Illustrations of
Many of the Species that vultures were “common summer residents” in the
northern part of the state but when “winters are severe they are sometimes
absent for a few weeks. . . The people think very much of them and protect
them.”
Vultures seemed rare in my youth but are common in my
maturity, especially in my current locale. I can recall the first time I saw
one circling over the city when I lived in Indianapolis, close to 20 years ago
now. I was shocked then, but it’s not an uncommon sight these days, in the era
of global climate change. And it seems like highly adapted behavior really.
There are lots of dead things in the
city.
I see them at least weekly here in my life on the river.
They are the clean sweepers of my rural world. And they’re some of my favorite
photographic subjects. Perched on tree limbs or indulging in a fresh or
festering dead critter, these guys fascinate me.
In my amateur birder world, I’ve noticed that vultures tend
to hang in committees of two most of the time when they’re snacking or perched.
But they often soar in larger graceful groups. They can soar high, high in the
sky as they scout for dinner because the vulture has one of the most sensitive
noses in the animal kingdom. They can detect the “plume” of rotting flesh even
when it’s in the weensiest concentration of particles mixed in the atmosphere.
A few parts per billion of stinky dead possum odor in the air sends up an
alluring aroma to these guys on the lookout for their next meal. Studies have
shown that they can find a dead critter within a few hours of its demise, even
if it’s buried under leaves or otherwise not visible. The turkey vulture’s
lamer cousin, the black vulture, is not nearly so well-endowed in the smell
sense. Turkey vultures rule in the world
of flying smellers.
Adding to the turkey vulture’s aural arsenal is their also
amazingly acute vision. A study comparing the turkey vulture's eyesight to their
cousin's, the black vulture’s, determined that the red-heads had just as densely
packed visual receptors as their far less smell-efficient cousins. So they see
as well and smell a lot better. Turkey vultures are winners with the right stuff.
The turkey vulture is a member of the order Falconiformes,
which also includes hawks, eagles, kites, harriers, osprey, falcons. Some common traits found in this order are
hooked beaks, sharp talons, that keen vision and a hind toe which opposes the
other toes – functioning somewhat like our thumbs. Traveling deeper into
taxonomic order, these birds are within the family of New World Vultures called
the Cathartidae. This includes the
California condor, the Andean condor and the king vulture of Central and South
America. Cathartes aura is the
scientific name specific to the turkey vulture.
Cathartes means “purifier”; aura’s synonyms in the dictionary are “atmosphere,
ambience, air, quality, character, mood, feeling, feel, flavor.” Vultures are atmospheric purifiers, a flying cleaning
crew. And for this I thank them.
I do, in fact, feel mightily thankful for the work of the
vulture. Just recently, when the momma fox I’d been watching raise a family of
kits was hit by a damn car, I tried to avoid driving the road where her
lifeless body lay so that I wouldn’t feel so dreadfully sad each time I saw her
there squished. But three days later, I forgot and instinctively headed down my
familiar trek only to see vultures gathered in their scavenging committee
around that dead mom fox’s body.
And I felt better.
Her death was no less tragic, but now I saw that it wasn’t wasteful. Her
body fed all those vultures. In the end, what was left of her probably also fed
a million microorganisms, but it was the vultures who brought the circle of her
life to a close for me.
Living as I do in a house in the country with two aging
cats, a river on one side and clover fields on the other, I’ve decided that if
one of my cats dies while I’m still in this house, I won’t bury him. I’ll take
his body into the fields and give him to the vultures. He’ll have a second use,
like the fox. I’ll watch for the vultures circling overhead and know that
he’s part of the circle of life, too. If
it were legal, I’d tell my sons to do the same with me. Put my body in the
woods, sing a poem over me and then watch the sky for my last hurrah.
