In my lifetime I have
been fortunate enough to have presented bird shows in many parts of the
country, and to a large variety of audiences.

I’ve talked to children
and adults, and everything in between.
As you might imagine, I have fielded a lot of questions on tons of
different topics. My favorite question
that I have only been asked a handful of times is, “If you could be a bird,
what kind of bird would you be?” One
of my favorite things about that question is that I get to reply, “a Turkey Vulture,”
without pausing.

The response that I
receive is usually surprise at least, and sometimes shock: “Why on earth would you WANT to be a
Vulture?” My reply: “Have you seen
the way they fly?”

Vultures are masters of
the air. Turkey Vultures can soar for hours without ever having to flap their
wings. They use their large wing area to catch the warm air rising from the
ground, called thermals, and ride it in a
circular pattern higher and higher. When they gain enough height, they can
simply soar out of the thermal and glide along, gradually losing altitude until
they find another thermal. In this manner Turkey Vultures can cover hundreds of
miles using very little energy. They hold their wings in a “dihedral,” with
wing tips being higher than the vulture’s back, so the wings form a V-shape, to take greatest advantage of the lift.

The best places to find
these warm uplifts of air known as thermals are over fields. As the sun heats
the ground, the lowest air begins to heat up and then rises in columns. Humans
in gliders can take advantage of these uplifts in the same way that Vultures
do.

When you watch Turkey
Vultures in flight, you can see the rather precarious agreement they have with
the laws of physics. Their bodies tip slightly from side to side as they adjust
to moving air currents and soar, sometimes just above the speed of stalling.
The primary feathers at the tips of a Turkey Vulture’s wings fan out almost
like fingers, and, if you watch closely, you can see the tiny adjustments they
make with these and their tail feathers as they fly.
Who wouldn’t want to fly
like that?

To get a really good look
at these “Masters of the Sky” come out and visit the World Bird Sanctuary on
any day except Thanksgiving and Christmas. As you walk down the trail past the Wildlife Hospital you
will see the exhibit that houses our resident Turkey Vultures. They will sometimes keep pace with
visitors, accompanying them along the fence line inside their enclosure as the
visitors walk down the trail. You
may even be lucky enough to see the many wild Turkey Vultures that sometimes
visit their resident cousins in hopes of getting a free meal.
