|The first Black Vulture arrives (Patrick Kelsey)|
It has taken me eleven years to finally get to spend a morning in a photographic hide to watch vultures come to carrion. It had been on my bucket list ever since this type of service started to be offered in Extremadura. So it was great anticipation that I booked in for my son and me at the La Cañada Hide
just south of the Monfragüe National Park. Jesús met us at the rendez-vous
spot just after seven in the morning and a few minutes later he welcomed us into the hide. From the information I had read previously I had already dispelled any notion of sitting on a stool in a cramped canvas structure, with the camera lens poking out of a slit in the fabric. This was a bricks-and-mortar construction, with plenty of space. Curtains divided the hide into two: at the back the entrance, with a table with bird notes and a cubicle with a chemical flush toilet. Beyond the curtains, a long window covered almost the entire width of the building, using spy-glass so that birds outside could not see us inside. There we could sit on comfortable armchairs, with our cold-box with drinks and snacks between us. In the distance we could see the cliffs of Monfragüe, home to Griffon Vulture colonies, infront of that lay a wide expanse of dehesa
whilst closer still was retama
broom scrub with a few scattered small holm oaks. Immediately in front of us, like an arena, was a patch of beaten earth with scraggly grasses and some tree stumps. It was on this stage that the props had been scattered: abbatoir-leftovers of livestock and even a few hens' eggs in case an Egyptian Vulture took a fancy.
The sun had not yet started to illuminate the set when the first act started. Within minutes of us taking our seats, a flurry of Azure-winged Magpies dropped in from the wings to start taking tiny fragments of meat. More surprising was the arrival of Crested Larks, which, barely visible against the dry earth in the half light of dawn, also approached the sections of vertebrae to peck at morsels. As they did so a Black Kite circled over and settled on top of the tree to our left. It was a pioneer but remained lonesome until we had been there for about half an hour, when at ten minutes to eight other Black Kites started to pour in, all settling in the trees, some making low passes over the bait, but none settling to feed. It was ten minutes after that when Patrick exclaimed "My God" as a Black Vulture flew to land on the top of the nearest tree to us. It was an exciting moment: neither of us had ever been that close to the Old World's largest bird of prey. Like the kites, it too remained perched, leaving the carrion for the time being to the Azure-winged Magpies. Over the next few minutes, a Griffon Vulture arrived to perch nearby, whilst an Egyptian Vulture appeared on a further tree.

We had been there an hour when the first Black Kite made a tentative landing and slowly, almost nervously approached the food. Others looked on from the trees. A Griffon Vulture, instantly dwarfing the kite also landed at the edge of the arena, but simply watched. But then the waiting was rewarded, as if by some coded signal, there was a surprise and seemingly sponanteous onslaught by a dozen Black Kites, piling onto a piece of carrion. The Azure-winged Magpies fled and were not seen again. Once the kites were positioned there, like some vanguard action, the vultures which had gardually been arriving in direct flight from Monfragüe and gathering on nearby treetops, started to descend. They assembled though at the periphery, in clusters, watching as the kites continued to push and shove around the bones. The drama unfolded and at times reached almost comic climaxes. As individual vultures approached the food, they performed a cheorography. Black Vultures lowered their necks and hunched their broad shoulders, half-spreading their wings like a villain's cloak and then taking huge slow-motion goose-steps as a threatening pose to ward off the kites. With more urgency, the long strides were switched to hops, with this massive bird literally bouncing kangaroo-like to gain pace. This menace was directed not just at the diminutive kites, but also to the other vultures, including congeners. Antagonism between the Griffon Vultures was also manifest by a bird standing on one-leg, with spread-eagled wings, raising the other leg slowly with its foot spreading open "palm" facing outwards to its opponent.
|A scrum of vultures (Martin Kelsey)|
And then, again with no sense of a advance notice, the vultures all moved-in in a matter of seconds. The stereotyped postures and prancing seemed subsumed by a brute force as birds plunged forwards and others descended from above. There was commotion and chaos, with a shreiking and wheezing. The vultures scrummaged and tumbled, dust was raised and the smaller kites and Egyptian Vultures were pushed aside by perhaps a hundred Griffon Vultures and over thirty Black Vultures. In the handful of minutes that this climax took place, the piles of carrion disappeared before our eyes. Fragments were dragged off by quarralling vultures into the scrub, or ingested on the spot.
As suddenly as this explosion of feeding has arisen, it subsided as the arena cleared and the big vultures either adjourned to the shade below the trees, or took off to the cliffs. In their place returned Black Kites and Egyptian Vultures, scurrying over the ground in search of scant remains, reminiscent of ragged-clothed hags scavenging across a deserted battlefield.

The morning was almost over and I lifted my binoculars to look through the party of vultures standing in the shade of the tree directly in front of us. Amongst the Griffon Vultures there was one which was slightly smaller and darker. Looking at it more closely, one could see that the tips of the feathers on the wing-coverts and underparts were pale, giving it quite a mottled appearance.

Fortunately it moved out of the shade and for a few minutes walked in the open, passing in turn Black Kites, Egyptian, Black and Griffon Vultures. As it walked it had a low-slung stance and in good light the tone of the plumage was almost like that of a Black Vulture, save the pale mottling. We were looking at a juvenile Rüppell's Vulture, a vagrant from Afica and the first I had ever seen in Extremadura.
|Juvenile Rüppell's Vulture (Martin Kelsey)|
In recent years individuals have been recorded, often in the summer, probably birds that have joined non-breeding Griffon Vultures as they return across the Straits of Gibralter into the Iberian Peninsula. It is a species of sub-Saharan Africa and would somehow link-up with young Griffon Vultures during their period of nomadic existence in Africa. The morning's show had encompassed high drama and comic interludes, but had finished with the emotional image of birds without borders, shifting between continents, embracing terrain of superficial similarity, the Extremeñan dehesa
with the Sahelian savannas.
