April 22, 2004 - Ugly on earth; a joy in the airThe Suffolk Times • April 22, 2004 Ugly on earth; a joy in the air JOHN ASKED ME RECENTLY what the big bird was that he saw drifting about in the sky. "Could it be an eagle ?" he asked. Well, that's always a possibility, but I think it was more likely a turkey vulture, because I've been receiving reports of turkey vultures from Orient to Riverhead. These masters of the sky have a six -foot wingspan and give the impression o floating on air. Or should I say soaring on air? In the entire avian world, none can rival the graceful flight of the turkey vulture. If you watch them closely you'll see that they do very little. actual flying or flapping of their wings Most of the time they're drifting on updrafts, thermals and winds, for it's on these they seem to travel effort- lessly all day long. Occasionally there are one, two or three flaps of the wings, but then it's back to soaring and drifting until they disappear from sight. The turkey vulture is our largest soaring bird besides the California condor, which is in the same family. A full -grown adult turkey vulture has a wingspan of '72 inches. In the air they're a joy to watch, giving us great pleasure as they rise on the thermals. On land they might seem repulsive to some. Their small, reddish heads look out of place on their big bodies. Their heads have no feathers so tney can reach inside a carcass without getting all messed up as they feed on dead animals of all kinds. Their large hooked bills help them tear pieces of flesh from a carcass. They often play the waiting game of death as they sit nearby and wait for a stricken animal to die. Focus Oftentimes they'll be seen on the ground with ON their wings spread out, NATURE looking like an aggressive, by Paul dangerous adversary. This is Stoutenburgh particularly true when the vulture has landed near a potential meal and wants to a E W T3 ° O d Ca ++ G � J O Y O E O E " E V O � � d N 41 O = 41 0 _NN 0 in � � d __ fII O N Y � N L o r =�'a� 0 o � ? c 4) > Q r- _ y 4a C W i W y •— (n v d 3 ° R o >; 40 ° O N 4a N _+ Y O vot�3 3 c o��*' o ° N C ° � o ++ _ > 4 3 > O ._ CD m 'o -4) m N '0 ca = a, N ` ° RoNa� N 41 O O rvE N E Q a�E�° o°��a (A 5 E E But for all its drawbacks on land, all is forgotten when you see this master of flight drifting above in the sky. If you look at a turkey vulture as it glides toward or away from you, you'll notice the wings appear in a slight "V" shape. This is called "dihedral." This wing shape is one way you can tell the difference between a turkey vulture and a black vulture. The latter has wings that are flat across when soar= ing. Another way you can tell the black vulture from the turkey vulture is by the use of its wings. The black vulture has a series of rapid wing - beats as it soars, whereas the turkey vulture flaps its wings very little in between gliding. This brings me to Barbara's experi- ence with a tur zey vu Lure just last week, right in our back pasture. A raccoon had been road - killed down at the end of our driveway and, having seen a vulture on our windmill recent. ly, I took the carcass up in the back lot in hope of attracting this scav- enger. Three days went by, and then it happened. Barbara came running into the house, calling, "Look! Look! Look!" She had spotted a turkey vul- ture hopping along with its wings spread out, headed toward the dead raccoon. As she watched, she could see it waddle back and forth on its short leas and stubby feet. The problem was that the neighbor ing crows saw him also, and if you know crows, you know they don't lik anything that looks like a hawk or an owl, so, with their raucous call, they collected all the crows in the area to join in tormenting the vulture. They all answered the battle call, diving and calling so much that it frustrated the poor vulture grid it took off, leav- ing its prize in the pasture. Sorry to say, Barbara's vulture did- n't stick around long. It just couldn't stand the heat from the crows, so, with a few clumsy hops and a jump, along with much wing beating, it was eventually air- borne. In my reading on turkey vultures taking off, the experts say they often lighten their load when frightened by regurgitating their last meal so the extra weight won't hinder their take -oft By the time I arrived, the turkey vulture was in the air. It was then we could see that it must have been molt ing — the time when the birds shed their old feathers to make way for new ones. There were gaps in its wings where feathers had fallen out and had not yet been replaced. Barbara, in the meantime, had gotten her camera, and was able to take a few shots for the record. I'm sure most of you have seen turkey vultures on the mainland, per- haps on your way south. Usually you start to see them from New Jersey on down. Here on Long Island, it seems they're becoming a bit more abun- dant. Years ago it would have been quite unusual to see a turkey vulture. I attribute their increase to the num- ber of deer killed on our highways. We have made an ideal situation for the vultures to stay around and feast on dead carcasses along the road. Turkey vultures need thermals or moving air to fly. I can remember, when we were camping down south years ago, seeing turkey vultures roosting in a big tree in back of our campsite. There must have been 25 or 30 of them spending the night there. When we got up in the morning they were still there. As a matter of fact they didn't move until the sun rose and warmed things up enough to cre- ate thermals. Then, one by one, the vultures took off, each one catching some part of their newly created transportation system. Slowly they rose, spiraling upward, and then drift- ed off for a day's shopping. We're told they find their meals partially by sight and partially by smell. Experiments have proved the smell theory. Researchers hid a car- cass under some brush so it was not visible from the ground or the air, yet a turkey vulture, with its keen sense of smell, was able to home in on it and go directly to the dead ani- These masters of the sky give the impression of floating on air. As I already men- tioned, the largest member of the vul- ture family, which some of you might be familiar with is, the California con- dor. This bird was almost extinct, but through conservation measures and some very technical rearing of young from eggs, it has been reestablished in the West as master of the sky. We'll probably never see a California con- dor on our East Coast. But the next time I go to California, my eyes will be searching the skies for this largest of the soarers and, who knows, per- haps I'll be able to see one. The members of the vulture family are a joy to see. They've been around for a long, long time. Archaeologists can vouch for that, as they've found remains of vultures that lived some 65 million years ago. So keep looking up and, sooner or later, maybe you'll get to see this master of the sky.
