By this time the sun would have sunk into a sunset of pink, green and gold, and we would make our way back to camp to crouch shivering over the fire, while in the distance, carried by the night wind, steady and bitterly cold, we could hear the noises of the seals, belching and roaring and splashing in the black and icy waters along the empty coast.

After we had spent some ten days filming the fur seals, I decided that, reluctant though I was to leave these beautiful and fascinating animals, we really ought to move on and try and locate the elephant seals before they left the peninsula in their southward migration. So, for the next four days, we drove to and fro about the peninsula searching for the elefanteria, and seeing a variety of wild-life, but no elephant seals.

I was amazed and delighted at the numbers of creatures we saw on the Valdes Peninsula. When I thought that, a few miles away across the isthmus, lay hundreds of miles of scrub-land which we had driven through without seeing a single living creature, and yet on the peninsula life abounded, it seemed incredible. It was almost as if the peninsula and its narrow isthmus was a cul-de-sac* into which all the wild-life of Chubut had drained and from which it could not escape. I wish that it were possible for the Argentine Government to make the whole peninsula into a wild-life sanctuary, for which it seems to have been designed by nature. To begin with you have a wonderful cross-section of the Patagonian fauna, all concentrated in a limited area, and most of it very easy to see. Secondly the whole area could be easily and effectively controlled by virtue of the narrow isthmus connecting it to the mainland; a check point on this could keep an adequate control on the people who entered and left the area, and keep an eye out for the sort of "sportsmen" (of which there are some in every country throughout the world) who would think it fun to chase guanaco in fast cars, or pepper the bull fur seals with buckshot.

In our search for the elefanteria we covered a lot of the peninsula, and the commonest bird we saw was undoubtedly the martineta, a species of tinamu.* It is a plump, partridge-shaped little bird, about the size of a bantam. Its plumage is a rich array of autumn browns, speckled and streaked with golds, yellows and creams in an intricate and lovely pattern. Its cheeks are a pale cream colour, with two black stripes showing up well on this background, one running from the corner of the eye to the neck and the other running from the edge of the beak to the neck. On its head there is an elongated crest of dark feathers, which curves like a half-moon over its head. It has large, dark eyes, and a general air of innocent hysteria.

Martinetas were to be seen everywhere along the rough roads in little groups of five or ten. Ridiculously tame, they would stand in the middle of the road, watching the Land-Rover's approach with wide eyes, bobbing their heads so that their silly crests twitched and fluttered, not bothering to move until you slowed down within a few feet of them and blew the horn. Then, stretching out their necks and holding their heads low, as if searching the ground for something they had lost, they would scuttle off into the scrub. They were most reluctant to fly, and in order to make them do so you had to pursue them for considerable distances through the undergrowth. Then, when they felt you were coming too near, they would launch themselves into the sky with an air of desperation. It was a curious, laboured flight, like that of a bird which has never learnt to use its wings properly. They would give four or five frantic flaps of their wings, and then glide until their fat bodies had almost dragged them to earth again, when they would give another series of wild flaps and then glide on a bit further. As they flew the rush of wind through their feathers produced a curious wailing note, that rose and fell flute-like, as they flapped and glided away. Their partiality for sitting in the middle of the road was due to the fact, I think, that it was only on these bare surfaces that they could construct the best dust-baths. In many places they had scooped out quite deep depressions in the red earth, and you could see three or four of them standing patiently waiting their turn, while one member of the flock rolled and kicked absurdly in the bath, fluttering its wings to throw the dust over its body.

These lovely, slightly imbecile birds are, of course, ground-nesting, and I think that they themselves, their eggs and their young, form an important item of diet among the carnivorous mammals of the peninsula, particularly the pampas fox, which is a common predator in the area. They are slim, grey, dainty little animals, with incredibly slender and fragile-looking legs. They appeared to hunt as much by day as by night, and were usually to be seen in pairs. They would suddenly dash across the road in front of us as we drove along, their bushy tails streaming out behind them like puffs of grey smoke, and on reaching the other side of the road they would skid to a halt and, squatting on their haunches, examine us craftily.

At one of the places in which we camped a pair of these little foxes paid us a visit, the only animal apart from the guanaco to do so. It was about five in the morning, and from my bed under the rear axle of the Land-Rover I was watching the sky turn green with dawn, while, as usual, trying to pluck up the courage to quit the warmth of my blankets and light the fire for breakfast. Suddenly, from the yellow scrub around us, the two foxes appeared as unexpectedly and as silently as ghosts. They approached the camp cautiously, with the conspiratorial air of a couple of schoolboys raiding an orchard, with many pauses to sniff the dawn wind. It was fortunate, at that precise juncture, that no one was snoring. I can put it on record that there is nothing quite so effective for scaring off wild animals as three women in the back of a Land-Rover, all snoring in different keys.

Having circled the camp without mishap, they grew bolder. They approached the ashes of the fire, sniffed at them deeply, and then frightened each other by sneezing violently. Recovering from this shock they continued their investigation and found an empty sardine tin, which, after a certain amount of low bickering, they proceeded to lick clean. Their next discovery was a large roll of bright pink toilet paper, one of the few luxury articles in our equipment. Having proved that it was not edible, they then discovered that if it was patted briskly with a paw it unravelled itself in the most satisfactory manner. So, far the nest ten minutes, they danced and whirled on their slender legs, hurling the toilet roll to and fro, occasionally taking streamers of it in their mouths and leaping daintily into the air, returning to earth with the paper wrapped intricately round their necks and legs. This game was conducted so silently and so gracefully that it was a delight to watch, and their agile bodies were well set off against the green sky, the yellow-flowered bushes and the pink paper. The whole camp site was taking on a gay carnival air, when somebody in the Land-Rover yawned. The foxes froze instantly, one of them with a piece of toilet paper dangling from his mouth. The yawn was repeated, and the foxes vanished as silently as they had come, leaving – as a souvenir of their visit – some hundred and twenty feet of pink paper fluttering in the breeze.
